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.

The geology of the Northwest is extremely interesting. This region has features thaat cannot be seen anywhere else in the country. For example, this region is part of the Ring of Fire.

Answer:

a. cold front

Explanation:

The weather forecast described aligns with the characteristics of a warm front, marked by increasing cloudiness, light but prolonged precipitation, and a gradual warming trend accompanied by shifts in wind direction.

The forecast indicating increasing high cloudiness and cold in the morning, with clouds increasing and lowering in the afternoon followed by a chance of snow or rain, points towards the characteristics of a warm front. Additionally, the prediction of precipitation ending by tomorrow morning and a turn towards warmer weather, along with wind direction shifting from easterly to southeasterly then southwesterly, align with the typical behavior of a warm front. A warm front is responsible for bringing light but prolonged precipitation, a steady increase in temperature as it passes, and a gradual change in wind direction, all of which matches the forecast description perfectly.

Clouds change from cirrus to nimbostratus.

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.

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.

The answer therefore is C. As this is the only option that is valid with the the premises.

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.

Question Options:

A. A and B

B. B and C

C. C and D

D. A and C

E. B and D

Answer: C and D. C is near Hawaii, D is along a mid-ocean ridge

Hotspot in geology is the surface manifestation of a plume that rises from deep in the celestial body's mantle.

Divergent margins also known as rift zones, shield volcanoes tend to form as two oceanic plates pull slowly apart and magma effuses upward through the gap.

The sites based on history that has volcanism related to a hot spot or divergent margin are Hawaii and the mid-ocean ridge. Hawaiian volcanoes within the Pacific Plate are caused by anomalous volcanism.

The correct answer is option (c), option (d) because  Volcanism related to hot spots is typically found in locations such as Hawaii. Hot spots are areas on the Earth's surface that have a high amount of heat flowing towards the surface from the mantle.

This often leads to volcanic activity that forms shield volcanoes, which is the case with the Hawaiian Islands. As the Pacific Plate moves over the stationary hot spot, a chain of volcanic islands is formed.

On the other hand, volcanism associated with divergent margins occurs at mid-ocean ridges. At these ridges, tectonic plates are moving away from each other, and new oceanic crust is formed through the eruption of basaltic lava. This process is part of seafloor spreading, which is a key component of plate tectonics.

In contrast, site A, located on an island arc, is associated with subduction zones where one tectonic plate is pushed beneath another, leading to the formation of volcanic arcs.

Site B, in the Andes, is also related to subduction, where the Nazca Plate is subducting beneath the South American Plate, resulting in the Andean volcanic belt.

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.

Answer:

PERMAFROST LAYER

Explanation:

Permafrost layer is usually defined as the thick layer of soil that is mixed with the broken rock fragments and other sediments, and are covered by ice throughout the year. These are mostly found in the higher latitudinal region, where the thickness of these layers ranges from a few meters to tens and hundreds of meters. The melting of these layers in these regions leads to an increase in the sea level.

For example, the permafrost layers of tundra and subarctic zones in Russia and its nearby areas, which have a thickness of about three meters.

Answer:

Permafrost

Explanation:

Among the cities provided, Belém, Brazil could be estimated to have relatively lighter winds due to its location closer to the equator and possible shielding from oceanic winds due to its geographical location around the Amazon Delta.

To determine which city would have relatively light winds based on surface-level horizontal pressure gradients seen in the Sea Level Pressure 2layer, we need to consider the spacing between isobars. Wind speed is directly related to the horizontal pressure gradient, i.e., the rate at which air pressure changes along a horizontal plane.

The question provides a hint: 'Large spacing between isobars typically indicates light winds.' Therefore, the city with the greatest space between isobars would have the lightest winds.

Without the exact pressure map, we can't definitively say which city this would be. However, based on general knowledge about wind patterns and geography, it is possible to roughly estimate. Coastal areas and areas at higher latitudes (closer to the poles) tend to have stronger winds due to larger pressure gradients, while areas near the equator tend to have lighter winds due to weaker pressure gradients.

Based on the location of the cities provided: Juneau, Alaska (coastal, high latitude), Belém, Brazil (near equator, but also coastal), Moscow, Russia (inland, high latitude), Santiago, Chile (coastal, mid-latitude), and Edinburgh, Scotland (coastal, high latitude), it could be reasonably estimated that Belém, Brazil might have relatively lighter winds. It is closer to the equator and although it is coastal, its geographical location around the Amazon Delta might provide some shielding from oceanic winds.

Answer:

Explanation:

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.

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.

1. The mass tourism can and can not be sustainable on the long term, depending on what kind of tourist site it is.

Explanation:

The mass tourism is sustainable on the long run for some places, and it is not sustainable for other place. The places where it is is sustainable are mostly the ones that are man-made and are well regulated and protected. Such tourist attractions are the Colosseum in Rome, Eiffel Tower in Paris, Big Ben in London etc.

On the other hand, the natural sites that are tourist attractions can not be sustainable, in general, on the long term. The reason for that is that if there are constantly lot of tourists on those places, they get disturbed, damaged, degraded, and over time may easily disappear, as those places are much harder to be protected directly and stop damaging them.

2. The local governments should be able to forbid tourist activities, especially when taken in consideration that the natural resources mass tourism sites belong to the government.

Explanation:

The natural resources tourism sites belong to the government, and in collaboration with the local authorities they control them together. Whenever the local government feels like the tourist place is in some kind of danger to be damaged, it should be , and it is able to stop any tourist activities there, or at least to restrict them and minimize them.

In the example of a tourist wanting to visit the redwood forest in California and not being allowed to, it does seem cruel. On the other hand, the tourist as disappointed he/she may be, should realize that it is done for the good of the forest, to be protected and continue to exist in the future.

Final answer:

While mass tourism can generate significant economic benefits, sustainability is a concern due to potential environmental and cultural degradation. Ecotourism and geo-tourism aim to balance tourism with conservation, and local governments may need to regulate visitor numbers to protect natural resources.

Explanation:

Mass tourism, while potentially a significant source of economic income, poses sustainability challenges for the long-term due to environmental and cultural impacts. Managed effectively, tourism initiatives such as ecotourism and geo-tourism aim to mitigate these impacts by promoting environmental protection and community involvement. National parks like Yosemite have shown that with careful management, tourism can coexist with conservation. However, the high traffic in other tourist destinations like Machu Picchu raises concerns about the degradation of these sites. Furthermore, tourism can fail to benefit local economies when profits are repatriated due to 'multiplier leakage,' and poorly managed tourism can have severe cultural and ecological consequences. Thus, local governments might find it necessary to impose restrictions to protect their natural resources, which could include limiting tourist numbers. The idea of stewardship is central to this discussion, asserting that natural resources should be preserved not just for the immediate economic benefit, but for their intrinsic value and the enjoyment of future generations.

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.
