The prominent mountain with a north-south trend shows the coal seam on both sides. The most minimal rise at which coal happens in the guide region is 5800 feet .

Through the course of geologic time, biota, minerals, and natural chemicals consolidated to form coal seams. The coal formation process is influenced by compression, heat, sedimentation, erosion, chemical energy, and other factors.

Within rock layers is a dark brown or black banded coal deposit known as a coal seam. Because they are underground, these seams can be mined using deep mining or strip mining, depending on how close they are to the surface.

Answer:

What is most likely the result of an increase in trade between countries?

A goods and services would become more expensive

B

Highlight

C

D

economic activity would increase

economic activity would decline

both countries would be worse off than before the increase

Explanation:

The most likely result of an increase in trade between countries is that economic activity would increase. When countries engage in trade, they can specialize in producing the goods and services that they have a comparative advantage in, and then trade them with other countries for goods and services that they are less efficient in producing. This specialization leads to increased efficiency, productivity, and output, which in turn spurs economic growth and creates more job opportunities. Therefore, increased trade is generally seen as a positive development that can benefit both countries involved by expanding their markets and creating new opportunities for economic activity.

Answer:

The Sun is the ultimate source of energy for almost all living cells on Earth as it powers photosynthesis and drives many of Earth's physical processes.

Explanation:

The ultimate source of energy for almost all living cells on Earth is the Sun. The Sun is the primary source of energy for the Earth, and it powers almost all cells as photosynthetic prokaryotes, algae, and plant cells harness solar energy and use it to make the complex organic food molecules that other cells rely on for the energy required to sustain growth, metabolism, and reproduction.

Photosynthesis is the process by which plants convert solar energy into chemical energy in the form of glucose and oxygen. This glucose is then used by living organisms as a source of energy. The energy used to drive the photosynthesis process is stored in the glucose molecules, which are then used by consumers, such as herbivores and carnivores, as food.

The sun is also the source of nearly all the heat and light that we experience every day, and it drives many of Earth's physical processes. For example, sunlight warms the atmosphere, which drives atmospheric circulation patterns, and it plays a role in evaporating water from the surface of oceans, lakes, and rivers.

In addition to being the primary source of energy for living things, sunlight also drives many of Earth's physical processes, such as the water cycle, which moves water vapor through the atmosphere and ultimately returns it to Earth's surface as precipitation.

Temperature-limiting pressure and differential stress are important metamorphic processes that can significantly affect minerals and rock textures. Both processes can result in the formation of new crystal structures and textures, as well as recrystallization of pre-existing minerals.

Temperature-limiting pressure can lead to the formation of foliation, which is a planar texture in which minerals are arranged in parallel layers. In addition, this process can lead to the formation of new minerals, such as mica and chlorite, from pre-existing minerals.

In general, these metamorphic processes can produce a wide variety of metamorphic textures and minerals. The intensity and duration of these processes can affect the amount and variety of metamorphic minerals and textures present in a rock.

Titan is bigger than Earth's moon, and larger than even the planet Mercury. This mammoth moon is the only moon in the solar system with a dense atmosphere, and it's the only world besides Earth that has standing bodies of liquid, including rivers, lakes and seas, on its surface.

Explanation:

Among our solar system's more than 150 known moons, Titan is the only one with a substantial atmosphere. And of all the places in the solar system, Titan is the only place besides Earth known to have liquids in the form of rivers, lakes and seas on its surface.

Volcanic activity created the soil that is important to the economy of the village of Vestmannaeyjar on the island of Heimaey, near Iceland.

Vestmannaeyjar is a collection of islands situated off the south coast of Iceland, and its literal meaning is "The Westman Islands." The largest of the islands, Heimaey, has a population of roughly 4,000 people. This island's economy is built on fish and fish processing, as well as tourism. The island has been recognized internationally for its exceptional bird watching, due to the high concentration of bird species residing there. Furthermore, the ground that volcanic activity created is also essential to the economy of the village of Vestmannaeyjar on the island of Heimaey.

Answer:

Explanation:

The depression formed after a volcanic eruption is typically called a "caldera." A caldera is a large, basin-shaped depression that forms when a volcano collapses into itself following a massive eruption or series of eruptions. The collapse occurs when the magma chamber beneath the volcano is emptied, causing the overlying rock to lose support and sink downward. Calderas can range in size from just a few kilometres across to many tens of kilometres, and they are often surrounded by steep cliffs or walls that rise several hundred meters above the floor of the depression.

The type of rocks that are formed by changing previously existing rocks through increases in temperature, increases in pressure, deformation, or chemical reaction is metamorphic rocks.

Metamorphic rocks are formed from previously existing rocks by changes due to temperature, pressure, deformation, and chemical reactions.

These types of rocks are made up of minerals that have been changed into other minerals or into different forms of the same minerals by heat, pressure, or chemical reactions that occur deep in the Earth's crust and mantle.

It occurs due to geological processes such as tectonic movements, compression, heating, and metamorphism. These rocks can be classified into two types: foliated and non-foliated.

Some examples of metamorphic rocks are marble, gneiss, schist, and slate.
