What’s the primary reason that mammals an avian dinosaurs thrived in the paleogene period

The waves are one of the agents that manage to cause large scale erosion and deposition. The influence of the waves in the erosive and deposition processes are along the coastlines. The composition of the waves is simply water, of course the water has certain other chemicals in it, but very importantly it has a lot of power pushing it forward. The combination of the chemical composition and the power results in the waves to be able to cause both chemical and mechanical weathering along the coastlines. By doing so, they manage to break the rocks in smaller pieces, and then easily move the material away, thus cause erosion. The material, depending on its size and weight, can be moved only few meters right next to the beach, further into the water but still close to the coastline, or on the beach itself. As the material is transported and then left off at certain places, we have deposition, which in turn causes constant pilling up of new material, so over time new and interesting features are forming from the deposited material.

Answer:

Leeward Mountain Slopes Encourage Warm, Dry Climates

In contrast to the windward side of a mountain which is moist, the leeward side typically has a dry, warm climate. This is because by the time air rises up the windward side and reaches the summit, it has already stripped of the majority of its moisture.

C. Potassium/argon dating

Explanation:

When it comes to dating old objects, science use a variety of methods, most of them based on known and stable physical/chemical reactions.

A. Principle of inclusions states that if you basically find a rock inside another rock, the inner one is older. Doesn't help in this case.

B. Uranium/lead dating  is used to date very very old stuff, like more than a million years old, up to 4.5 billions years - the age of our planet. If I suspect the rock is about 200,000 years, this won't do.

C. Potassium/argon dating  is used to date rocks that are older than 100,000 years, so this would be the good technique to use.

D. Carbon/nitrogen dating is use to date stuff ranging from about 5,700 years to 50,000 years. Not useful in this case.

Answer:   C Potassium/argon dating

Explanation:  you would use potassium argon dating

The axial tilt is defined as the angle between the direction of the positive pole and the normal to the orbital plane. The angles for Earth, Uranus and Venus are approximately 23°, 97°, and 177° respectively.

Hope this helps:)

The planet that has the greatest angle between its axis of rotation and the normal to the plane of its orbit is Uranus.

Most planets are tilted in their orbit but Uranus has the greatest axial tilt of 98 degrees essentially meaning it is spinning on its side. Axial tilt is angle between rotational axis and orbital axis.

The large axial tilt causes the planet's the North Pole to be next to the equator and Astronomers believe that this tilt was caused by a collision with material that may be the size of the earth. The collision which may have occurred once knocked Uranus off of its normal orbital place.

The correct answer is - water cycle.

The water cycle represents the movement of the water between the different spheres on the Earth, including the atmosphere, lithosphere, hydrosphere, and biosphere. This cycle has a circular movement. The water on the Earth is heated up by the sunlight and it starts to evaporate, turning into gas, or rather water vapor. The water vapor is very light so it moves up in the atmosphere. Once it reaches the colder parts of the atmosphere, the water vapor condensates, creating small drops of water and clouds. The gravity makes the drops fall on the surface of the Earth in the form of precipitation. That water gets inside the ground, is consumed by the living organisms, and gets into the water bodies, and from all of them it evaporates again.

The gases that surround a star or planet — called the object’s atmosphere — vary from one celestial object to the next. ... The Earth’s atmosphere is primarily composed of nitrogen and oxygen, although carbon dioxide, argon, neon, helium, krypton, hydrogen, ozone, neon, carbon ...

The atmosphere includes all the gases which surrounds a star or a planet.

The atmosphere includes gases like nitrogen, oxygen, argon, and many more gases. An atmosphere is the layers of gases surrounding a planet or a different celestial body.

Our Planet Earth's surroundings consist of approximately 78% nitrogen, 21% oxygen, and one percentage of different gases.

Thus, The atmosphere includes all the gases which surround a star or a planet.

Answer:

New crust, sometimes islands/mountains

Explanation:

Divergent boundaries are when two tectonic places are moving away from each other. In the current configuration of Earth, that happens in the ocean.

When plates move away from each other, they leave a gap.  That gap is filled with lava that solidifies quickly and forms now crust.  If the ocean floor is relatively shallow, and the lava pressure is big enough, that can lead to the formation of new islands, mountains/volcanoes on top of the gap.  That's basically how the Galapagos islands were created.

The resources of Antarctica are prevented from being used primarily by the Antarctic Treaty System, extreme environmental conditions, and global concern for environmental conservation.

The main factor preventing the resources of Antarctica from being used is the Antarctic Treaty System. This international agreement was signed in 1959 by 12 countries and has been joined by many more since then. The treaty prohibits military activities, mineral mining, and any commercial exploitation in Antarctica, aiming to preserve the continent's unique environment and scientific research.

Additionally, the extreme environmental conditions in Antarctica pose significant challenges to resource extraction. The continent is covered in ice, making it difficult to access resources, and the harsh climate and isolation make it costly to establish and maintain infrastructure.

Finally, the global concern for environmental conservation and sustainability also plays a role in preventing resource exploitation in Antarctica. Many nations and organizations prioritize the protection of this pristine wilderness, recognizing its global significance and the potential environmental consequences of unchecked resource extraction.

Answer:

glacial till

Explanation:

The glaciers are one of the numerous things that manage to cause erosion and deposition on the planet, thus being active contributes to the formation of the landscape. Despite the glaciers looking all smooth and clean, they are actually not, especially at their bottom and their sides. They actually manage to erode the and pick up lot of rocks, sediments, debris that they are in touch with, the ice traps them, and their enormous mass and force moves them along with the glaciers. That material can travel with the glaciers until the glaciers reaches its point of melting, or totally melts, traveling long distances with it. Once the glacier is melted, the material is deposited as loose, unsorted deposits, varying in size, shape, composition. All of the deposits by the glaciers are collectively called glacial till, and most often they come in the form of moraines.

Answer:

Underground

Explanation:

The majority of the liquid freshwater reserves are found underground, or rather the groundwater. The groundwater accounts for only 12% of the total freshwater reserves on the planet, but it is still the largest reservoir of it in liquid form. The reason for this is that the lakes and rivers only have around 1% of the total freshwater reserves, thus significantly less, not to mention that large portion of them are polluted nowadays. The biggest problem is that the majority of the freshwater is not actually in liquid form, but instead it is in the form of ice, trapped around the poles and on the highest mountains in the form of glaciers and polar caps. That water accounts for 87% of the total freshwater reserves. The groundwater, despite being a relatively rich source of liquid freshwater, also faces lot of problems, as the human population constantly needs more and more of it, usually taking more then what the nature can replace, living them dry eventually.

Answer:

true

Explanation:

Asia is the largest continent on Earth, spanning a vast geographical area, which makes it the longest to cross by airplane from east to west. Historical skepticism about long-distance air travel has been proven wrong by advancements in aviation technology. Yet, despite these advancements, Asia's size still dictates it as the most time-consuming continent to cross by air.

The continent that would take the longest to cross by airplane from east to west is Asia. Asia is the largest continent on Earth and spans across an extensive geographical area that includes diverse terrains such as deserts, mountains, and plains. If we consider real-world geography, taking for instance the distance between an eastern point in Asia, such as Japan, and a western point, such as Turkey, it would certainly require a lengthy flight time as opposed to crossing continents of smaller size.

Furthermore, Charles Lindbergh's historical flight across the Atlantic Ocean, which lasted thirty-three hours, pales in comparison to the time it would take to travel across Asia. Moreover, the complementary shape of the east coast of South America and the west coast of Africa, and similar discussions about continental drift, do not impact the fact that Asia, with its substantial east-west breadth, stands as the most time-consuming continent to cross by air.

In modern times, with advanced aviation technology, airplanes can now cover long distances without stopping for refueling, and transcontinental flights are routine, which would have been unimaginable to pioneers such as Orville Wright. Even so, Asia's vast span dictates longer flight durations than other continents, making it the longest to cross from east to west by airplane.

e. Transform fault

Explanation:

The San Andreas tectonic feature is of transform fault type. This basically means that we have in question a fault that has been formed at or near a transform plate boundary. In this case, it is the transform plate boundary between the North American tectonic plate and the Juan de Fuca tectnic plate. It has to be noticed though that Juan de Fuca is actually not a single plate anymore, but instead it has cracked into three smaller parts, with the part being nearby San Andreas making a transform plate boundary with the North American plate. In this type of boundary, the plates slide past each other, but they still manage to create a lot of tension around the boundary, resulting in cracks in the crust, or rather faults. The faults are parallel with the boundary, and can vary a lot in width and depth, and one of the best examples in the world for this type of fault is San Andreas in California.

Answer:

the plates float on the fration lines

Explanation:

The Earth's tectonic plates float on the asthenosphere, a semiliquid layer beneath the lithosphere. The movement of these plates is primarily driven by mantle convection, a heat transfer process within the Earth.

The tectonic plates of the Earth float on the asthenosphere, a semiliquid layer situated below the lithosphere which includes the Earth's crust and the uppermost part of the mantle. The numerous tectonic plates behave akin to jigsaw puzzle pieces, fitting together on the asthenosphere. These plates move due to the process of mantle convection. Mantle convection is a heat transfer process, where warmer material rises while cooler material sinks, transporting heat from the interior of the Earth to the upper mantle. This movement and heat transfer process allows for plate tectonics, leading to geological changes on the Earth's surface such as continental drift, mountain building, and volcanic eruptions.

Anthropogenic pollution is exemplified by sulfur dioxide emissions from coal burning power plants, one of the main contributors to acid rain and outdoor air pollution due to fossil fuel combustion.

The anthropogenic form of pollution refers to the pollution originating from human activities as opposed to natural processes. An example that illustrates anthropogenic pollution is sulfur dioxide released from a coal burning power plant. This type of emission is a major contributor to outdoor air pollution and the formation of acid rain, which are primarily due to the combustion of fossil fuels.

Anthropogenic sources, as opposed to natural sources, like volcanic eruptions or sea salt aerosols, include emissions from stationary sources such as power plants and mobile sources like vehicles and aircraft. These emissions can include sulfur dioxide, nitrogen oxides, carbon monoxide, particulate matter among others. They can significantly harm health, the environment, and contribute to climate change.

Final answer:

The example of anthropogenic pollution from the provided options is sulfur dioxide released from a coal burning power plant, as it is a result of human activities, unlike volcanic eruptions, forest fires by lightning, or sea salt aerosols which are natural.

Explanation:

The anthropogenic form of pollution refers to pollution that originates from human activities, as opposed to natural sources. In the context of the student's question, the correct answer illustrating an anthropogenic form of pollution is C) sulfur dioxide released from a coal burning power plant. This is because sulfur dioxide and other harmful emissions released during the burning of coal are a result of industrial activities aimed at generating electricity and other forms of energy - which are clearly human-driven processes. On the other hand, options A, B, and D represent natural sources of pollution such as volcanic eruptions, forest fires caused by lightning, and sea salt aerosols, respectively, which are not caused by human activities.

Asia and North-America

Explanation:

The Bering strait is a portion of about 47 miles (75 km) that separates Asia (Russia) and North-America (state of Alaska, USA).  Let's remember that Alaska belonged to Russia and was bought by the US.

That straight is a place with very harsh and extremely violent weather fueled by cold Arctic water and winds.

20,000 years ago, that straight was solid ice and that's how human migrated from Asia to North America (and went further South afterwards).

Answer:

I'll assume you have to match the name with their definitions.

1. aquifers

underground water sources  

That's because of the presence of porous rocks that let water pass through them and reach an underground cavern that then acts as a tank.

2. delta  

a broad, triangular-shaped land area at the mouth of a river

That's common especially in larger rivers that meet their destination point (usually the ocean).

3. oasis  

a small fertile area in the desert, usually a place where water is close to the surface (plural - oases)  

We all heard about oases in the desert, where human and animals alike gather to drink.

4. rain shadow  

an area that receives less precipitation because of its location on the leeward side of a mountain

That's common in high mountains region where the mountains are so high they block the passage of clouds to the other side.

Final answer:

An aquifer is an underground layer of rock that stores water. Oases are small fertile areas in the desert formed around underground water sources. A rain shadow is an area that receives less precipitation on the leeward side of a mountain.

Explanation:

An aquifer is an underground layer of rock that stores water. It is made up of sub-surface, porous rock that holds water. Aquifers are commonly drilled to provide water for agriculture and personal use. They are an important source of freshwater, particularly in arid climates.

An oasis is a small fertile area in the desert, usually a place where water is close to the surface. Oases are formed around underground water sources that reach the surface via wells or springs. They are green dots of civilization in the desert.

A rain shadow is an area that receives less precipitation because of its location on the leeward side of a mountain. When moist air is forced to rise over a mountain range, it cools and releases moisture, resulting in precipitation on the windward side. The leeward side, or rain shadow, receives less precipitation and can be drier.
