Using the concepts of rocks, we got that the expansion of deeply buried rocks after they are exposed by erosion causes the formation of Fractures.

Fractures along which the rock has slipped relative to the other side are called faults, whereas fractures that are the simple cracks where the rock has pulled apart by the small amount are joints. Any fracture or system of fractures along which the Earth moves is known as a fault. Faults allow the blocks to move relative to each other which actually results to an earthquake.

When deeply buried rocks are uncovered by the erosion, the removal of weight allows them to relax and expand. Produces fractures and it increases in porosity. This stress-relaxation process actually reduces the strength of rocks, opening up passageways/storage places for the water to attack and further weaken the rocks.

Hence, the expansion of deeply buried rocks after they are exposed by erosion causes the formation of Fractures which reduce the strength of the rock.

Igneous rock composition however is dictated by the amount of silica present in the rock. high silica content will result in a Felsic composition.

A silicate mineral, magma, or rock that is abundant in lighter elements including silicon, oxygen, aluminum, sodium, and potassium is referred to as felsic. In comparison to mafic magma/lava, felsic material has a greater viscosity.

The term "felsic" in geology refers to igneous rocks that are highly abundant in the components that go into making feldspar and quartz. Felsic rocks often have light colors and specific gravities under 3. Granite is the most typical felsic rock. Rocks classified as felsic have a silica concentration greater than 65 percent according to a frequently used categorization system. Rhyolite and granite are felsic rocks, having an average silica concentration of roughly 72%, according to compilations of several rock studies.

The correct option is option (c), i.e, both (a) and (b) are correct. Sierra Nevada mountain is created by seismic fault and Lewis overthrust in glacier national park in Montana is created by folding.

The Sierra Nevada Fault, an active seismic fault in California's Sierra Nevada mountain massif, runs along its eastern boundary. It extends around 600 km (370 mi) from just north of the Garlock Fault to the Cascade Range, forming the eastern escarpment of the Sierra Nevada.

The Lewis Overthrust is a Rocky Mountain thrust fault structure that can be found in the bordering national parks of Waterton Lakes in Alberta, Canada, and Glacier in Montana, the United States. The structure was created when two tectonic plates collided about 170 million years ago, pushing a wedge of rock up to several miles thick 50 miles (80 kilometres) eastward, where it now lies on top of the softer rock from the Cretaceous period, which is 400–500 million years younger.

The natural vegetation region that is best for agriculture is the Grassland vegetation region.

There are five main vegetation regions which are forests, deserts, tundra, grassland, and the places covered with ice sheets. Of these five, only 2 are suitable for agriculture and they are the grassland vegetation region, and the forest vegetation region.

The grassland vegetation region is most often used for agriculture because it is found more abundantly than the forest vegetation. There is also the fact that it is easy to harvest and easy to plant on because it doesn't have as many trees as the forest vegetation region.

Using a grassland vegetation region is also more environmentally friendly because less trees are cut as would have been done in the forest region. Overall, the grassland vegetation region is best for agriculture and the environment.

But, the natural occurences that occurs at the convergent boundaries between two continental plates is that new continental crust is created and oceanic crust is destroyed.

The boundary is an area on Earth where two or more lithospheric plates collide, where one plate eventually slides beneath the other with a process known as subduction.

The subduction zone is where many earthquakes occur and collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, orogenesis, destruction of lithosphere, and deformation.

The period is sometimes called the Age of Amphibians, during which amphibians became dominant land vertebrates and diversified into many forms including lizard-like, snake-like, and crocodile-like.

Explanation:

The "Carboniferous Period" is sometimes referred to as the "Age Of Amphibians".

Amphibians are a group of small animals that need water or a damp environment to survive.

These species include frogs, toads, salamanders, and newts. Each creature has incredibly thin skin that enables breathing and water absorption.

Furthermore, amphibians have special skin glands that produce useful proteins. Some allow the animal to take in or release gases like carbon dioxide, oxygen, and water. Others fight off fungal or bacterial infections. Each species also employs one or more for defense.

To warn potential predators, the most deadly frogs are also the most colorful. Curare, for instance, is found in the skin of colorful poison dart frogs. Another distinctive characteristic of most amphibians is their life cycle of egg-larva-adult.

Light, what is it?

The ocean's surface may reflect moonlight, brightening it and improving vision, depending on the moon's phase. The full moon is when this is the brightest.

During the day, light can travel up to 1000 meters and beyond 200 meters, but it is much less strong and is essentially imperceptible to the human eye. The sun's light can reach sea depths of up to 1000 meters.

By releasing less moisture into the sky, cold ocean currents can stop the formation of glaciers, and stronger ocean currents can bring colder water to the surface, which cools the land. The impact of continental drift on glaciers, ocean currents, and the overall climate is accurately described by this phrase.

Due to the fact that melting glaciers hold their water on land, runoff significantly increases the amount of water in the ocean, raising the sea level.

When the climate changes, glaciers, and ice caps react to the changes in the atmosphere and the ocean, which also clearly indicates that the climate is changing globally.
