The annual march of the seasons and the passage of the subsolar point between the Tropics of Cancer and Capricorn affect these stations. Can you detect from your temperature graphs these seasonal effects
Answer:
Subsolar point is point were the sun is believed to be directly over head and the rays of the sun strike at the perpendicular the surface.
Explanation:
The annual season is those that are divided into the summer, winter and the autumn and spring with the axial tilt of the sun and they are represented by the summer as starting from the 28th Feb and the winter in the 1st December with the spring on the 1st March and the autumn on the 31st August. And the spring begins when the daily annual range of the temperatures rises above the 0 degrees and the summer when its plus 10 degrees. And thus areas the low and mid-latitudes, high latitudes as tropics, torrid and the frigid areas have been demarcated with the reference to the tropics of cancer and the Capricorn.Tsunami wavelengths can be as great as ____________.

Imagine two adjacent playing fields, one with a wet surface and the other with a dry surface.
If you simultaneously measured air temperature above each surface on a sunny summer afternoon, where would you expect the higher temperature? Why?
a. Above the dry field. Because of the presence of water, more solar energy is reflected from the wet field surface, and hence its temperature stays cooler,
b. Above the wet field. Thanks to the hydrogen bonds, water can absorb a lot of heat, thus keeping the wet surface warmer.
c. Above the dry field. Evaporation of water over the wet field requires extra energy, which keeps the surface cooler.
d. Above the wet field, because it has a lower albedo.
Answer:
(C) Above the dry field. Evaporation of water over the wet field requires extra energy, which keeps the surface cooler.
EXPLANATION:
If you simultaneously measured air temperature above a dry and wet surface on a sunny summer afternoon, you would expect the higher temperature above the dry surface because Evaporation of water over the wet field requires extra energy, which keeps the surface cooler. It takes more energy to heat and cool water than it does dry ground
Answer:
c. Above the dry field. Evaporation of water over the wet field requires extra energy, which keeps the surface cooler.
Explanation:
Out of these two playing fields, the one with a dry surface would most likely have the higher temperature. The main reason for this is that the wet field is consuming the heat in order to dry the ground. The process of evaporation requires the use of some of this heat, keeping the surface cooler. However, once the field dries, then the temperature is likely to be the same in both fields.
Which of the following statements are true?

Explanation:
The geographic north and south poles refers to the two geographical location/points, where the earth's axis spins. And the magnetic north and south poles refers to the direction towards which a compass needle points.
The geographic north pole and the magnetic south pole of earth is the same, and two bar magnets where one having the north pole and the other having the south pole can attract each other. Similar poles of two bar magnets cannot attract one another, whereas they repel.
Thus, the correct answers are options (3), (4) and (5).
Answer:
Earth's geographic north pole is actually a magnetic south pole.The south poles of two bar magnets will repel each other.The north pole of a bar magnet will attract the south pole of another bar magnet.Explanation:
The earth's geographical north pole is also called as the north pole or the terrestrial geographical north pole and is defined as the point of the northern hemisphere and is the magnetic south pole of the earth. The earth magnetic poles have equal are properties and thus are close relation and opposite to each and every property.
On 9 January 1857, the San Andreas fault segment between Cholame and San Bernardino broke loose at its northwestern end, and the rupture propagated southeastward in the great __________ earthquake with a magnitude of about 7.9.
Answer:
On 9 January 1857, the San Andreas fault segment between Cholame and San Bernardino broke loose at its northwestern end, and the rupture propagated southeastward in the great Fort Tejon earthquake with a magnitude of about 7.9.
Explanation:
The Fort Tejon earthquake, which occurred on January 9, 1857, is considered the strongest earthquake that shook the state of California. It is estimated at a strength of 7.9. Its strength is therefore comparable to that of the 1906 San Francisco earthquake. It occurred along the San Andreas Fault 362 kilometers between Parkfield and San Bernardino. The two plates that meet along this disturbance shifted up to nine meters during this quake.
California was still sparsely populated in 1857. Unlike the New Madrid earthquake of 1811, there are hardly any records of people who have experienced this earthquake. For this reason it is only known among seismologists. According to current research, its epicenter was located near the California city of Parkfield. However, it got its name because of the army camp Fort Tejon, which was located on the Tejon Pass, reported it.
Only one death was reported as a result of the earthquake. The person died in the collapse of an adobe house at Reed’s Ranch in Gorman, very close to the fault. Most of the buildings in Fort Tejon were badly damaged and several people were injured. Some buildings in Los Angeles were destroyed, but no major damage was reported.
Final answer:
The rupture that occurred on 9 January 1857 on the San Andreas fault was the great Fort Tejon earthquake, with a magnitude of about 7.9, indicating the significance of seismic activity along the fault.
Explanation:
On 9 January 1857, the San Andreas fault segment between Cholame and San Bernardino broke loose at its northwestern end, and the rupture propagated southeastward in the great Fort Tejon earthquake with a magnitude of about 7.9. This event, alongside others such as the 1906 San Francisco Earthquake, underscores the seismic activity along the San Andreas Fault and the potential for future significant seismic events. While some areas of the fault show moderate seismic activity like Parkfield, others such as parts of the 1906 and 1857 ruptures have low seismicity, suggesting a potential for larger earthquakes almost up to a magnitude of 8.
Earth's main energy inputs are
(A) near infrared and far infrared (i.e., longwave radiation).
(B) ultraviolet, visible, and near infrared radiation.
(C) longwave radiation and ultraviolet light.
(D) gamma rays, X-rays, and ultraviolet radiation.
Answer:
Earth's main energy inputs are longer radiation and ultraviolet light.
Explanation:
Earth's main source of energy is solar energy which is obtained from sun.
Sun light that is emitted from sun broken down into 3 major components-visible light with shorter wavelength, Ultra violet light which also contain shorter wave length that is 380 nm and infrared light with longer radiation that is 700 nm.
But sun emits 44% of its light as shorter wave length which is also called as visible wave length and 7% contain ultra violet light
Answer: ultraviolet, visible, and near infrared radiation.
Explanation: The main source of energy input of the earth is the SUN.
Energy from the sun is essential for many processes on Earth including warming of the surface, evaporation, photosynthesis and atmospheric circulation.
Though the sun emits all of the different kinds of electromagnetic radiation, 99% of its rays are in the form of VISIBLE LIGHT, ULTRAVIOLET RAYS, and INFRARED RAYS.
Which of these statements is true about plate tectonics? Continental drift on the Earth is caused by circulating convection currents in the deep interior. Continental drift on Earth is caused by the slow precession of Earth's spin axis. Tidal forces from the Moon and Sun causes the slow drift of continental land masses. Two crustal plate boundaries can easily slide past each other because of the presence of seawater. The Mid‑Atlantic Ridge is an area of continuous seafloor erosion which creates powerful earthquakes along a subterranean mountain chain.
Answer:
continental drift on the Earth is caused by circulating convection currents in the deep interior
Explanation:
The Tectonic plates make up the earth's crust and the movement of these tectonic plates that make up the earth's crust is due to the movement of the Magma of the earths crust that flows/moves in the form of convectional currents.
The earths crust acts as the heat insulator which when heated up due to internal pressures releases hot Magma flowing in the form of convectional currents apart from the convectional currents causing the plate tectonics to move other factors like ridge push and slab pull can also cause the plates to move as well.
The true statement about plate tectonics is that continental drift is caused by circulating convection currents in the Earth's deep interior, which move the tectonic plates.
Explanation:The statement that is true about plate tectonics is: Continental drift on the Earth is caused by circulating convection currents in the deep interior. In the Earth's mantle, heat from the core causes convection currents. These currents cause molten rock to flow, which moves the tectonic plates - large sections of the Earth's crust - on the Earth's surface. This process is behind continental drift.
Continental drift has no direct link to the precession of the Earth's spin axis. Tidal forces from the Moon and Sun affect Earth's water bodies, but not the drift of continental land masses. Seawater does not enable plate boundaries to slide past each other more easily and the Mid-Atlantic Ridge, a result of divergent plate boundaries, is a site of seafloor spreading, rather than continuous erosion and source of earthquakes.

With the addition of water, the minerals in granite rocks chemically weather into other minerals, known as products. Test your knowledge of the by-product of each mineral as a result of chemical weathering by labeling the minerals below with their respective products.
1. Feldspar
Clay, no chemical change, or limonite?
2. Quartz
Clay, no chemical change, or limonite?
3.Olivine
Clay, no chemical change, or limonite?
Answer:
Feldspar-clay
Quartz- No chemical change
Olivine- Limonite
Explanation:
When chemically weathered, some of the original minerals of granite change into different minerals.
Feldspar, for example, tends to hydrate and transform into a clay mineral.
Iron-rich minerals, like olivine, turn into limonite by chemical weathering. Quartz is considerably resistant to chemical weathering, so it´s the least susceptible to the chemical change.

A large, major hurricane is predicted to come ashore with its eye near the Louisiana/Mississippi border. You are asked to recommend if more resources should be sent to Louisiana or to Mississippi in preparation. What do you recommend
Answer: As a consultant for such a large disaster, I would recommend that instead of focusing on resources to Louisiana or Mississippi, the authorities should focus more on the EVACUATION OF PEOPLE from those locations. In my opinion, this is the best option because it is better to be safe than sorry. Since it was predicted that the hurricane that is approaching is large and major, the extent of the damage will definitely be large and major. The best thing will be for the hurricane to come and meet no one, than come and meet people.
Explanation:
The Northridge and Landers earthquakes may be part of a pattern of increasing seismicity prior to failure along the segment of the San Andreas opposite Los Angeles. True False
Answer:
The answer is True.
Explanation:
In a research that combined seismic, geologic and geodetic data regarding Northridge and Landers earthquakes, and assessed the two earthquakes, the Poissonian and seismic hazard models showed that there was between 80 and 90 per cent probability that Northridge and Landers earthquakes may be part of a pattern of increasing before any type of failure along the southern segment of the San Andreas.
Answer:
True
Explanation:
The Northridge earthquake took place on January 17, 1994 in the County of Los Angeles. The earthquake could be felt as far as Las Vegas, Nevada, and it had a death toll of 57, with more than 8,700 injured. On the other hand, the Landers earthquake took place on June 28, 1992 in Southern California. It had a magnitude of 7.3, and was much more powerful than the Northridge earthquake. Both of these are considered to be part of a pattern of increasing seismicity of the San Andreas fault.
The relative humidity (RH) of surface air (2 m height) tends to decrease from morning into early afternoon, especially when the sun is shining and the weather is quiet and stable. As evening approaches, RH usually rises again. Explain the physical basis for this behavior (not discussed in text).
Answer:
The Relative Humidity tend to decrease from morning to afternoon and as evening approaches increases and this as a result of the relationship between RH and increase in temperature
Explanation:
The relative humidity is the amount of water vapor the air is holding right now as a percentage of what it would be holding if it were saturated. If you increase the temperature, however, the amount of water vapor the air can hold increases, so the relative humidity decreases and vice versa for decrease in Temperature. This explains the reason for high RH in the morning decreasing into the afternoon and rising again in the evening.

These air masses are modified by the warm waters of the Gulf over several days and are drawn back to the north. These air masses may be reclassified as mT because of the increase in moisture and warmth of the air mass. These are called ______.
Answer: These are called WARM FRONT.
Explanation: In meteorology, warm front is known as a trailing edge of a retreating mass of cold air. It involves a warm air mass replacing a cold air mass. They are typically located on the equator-facing edge of an isotherm gradient.
Clouds ahead of the warm front are mostly stratiform, and rainfall gradually increases as the front approaches.

Answer:
As this less than 2 mm in diameter, with an appearance of dust or sand. These pyroclasts are commonly pea to walnut sized.Lapilli, or cinders, range from 2 mm to 64 mm in diameter. Blocks And bombs represent the largest fragments, which are greater than 64 mm. Blocks are erupted as hardened lava with a mostly angular shape, while bombs semi-molten and develop a streamlined-shape while flying through the air.Explanation:
A pyroclastic material is a particle ranges for the 2 to 64 mm in diameters and they can range of the volcanic bombs to the ash and the lavas.Like Lapilli or the cinders, they have a diameter of about 64 mm. They extend to miles form the volcano when they blast as blocks and can devastate lands, life, and property within there paths.Pyroclastic material ejected from volcanoes during explosive eruptions is categorized by size. Ash is less than 2 mm, lapilli are 2-64 mm, and blocks and bombs are greater than 64 mm, with blocks being angular and bombs smoother due to being partially molten.
During an explosive volcanic eruption, various sizes of pyroclastic material are ejected, each with different names based on their size. The smallest particles, known as volcanic ash, are less than 2 mm in diameter and can resemble dust or sand. These fine particles can travel long distances and carry potential health hazards, like causing respiratory issues.
Slightly larger fragments are called lapilli or cinders, which have diameters ranging from 2 mm to 64 mm, roughly the size of peas to walnuts. These pyroclasts tend to fall closer to the volcano. The largest pyroclastic materials are blocks and bombs which are greater than 64 mm. Blocks are already hardened when ejected, taking on a mostly angular shape, whereas bombs are semi-molten during ejection and can develop a streamlined shape as they fly through the air.

Storms that form in or travel to the Caribbean Sea or Gulf of Mexico are virtually certain to impact land areas. There were multiple examples of these tracks in 2018. Hurricane Irma is one particular example.
Storms that form in the Caribbean or the Gulf of Mexico have a high chance of impacting the land. Examples include Hurricane Katrina in 2005 and Hurricane Irene in 2011. These storms and changes in global weather patterns indicate that hurricanes are increasing in severity and frequency.
Explanation:Storms that form in or travel to the Caribbean Sea or Gulf of Mexico are virtually certain to impact land areas. There were multiple examples of these tracks in 2018. One particular example of such a storm is Hurricane Katrina, which struck the Gulf Coast in 2005. The hurricane caused considerable devastation and was a major natural disaster for the United States.
Another example is Hurricane Irene, which hit New York City in 2011. A satellite image shows the immense size of the phenomenon shortly before the storm made landfall. This storm and countless others like it are one demonstration of how Earth's titled axis of rotation, moderately rapid rotation, and oceans of liquid water can combine to produce violent weather.
Since the 1980s, storms have increased in frequency, intensity, and duration, as evidenced by the exceptionally active 2020 hurricane season. All types of weather are becoming more extreme due to changes in precipitation patterns and increasing carbon dioxide levels in the oceans. These phenomena are, in part, accountable for longer droughts, increased flooding, and more acidic oceans.
