. What is the importance of magma composition?

Most of the mantle and crust are solid, so the presence of magma is crucial to understanding the geology and morphology of the mantle. Differences in temperature, pressure, and structural formations in the mantle and crust cause magma to form in different ways.

How magma is formed?

Magma forms from partial melting of mantle rocks. As the rocks move upward (or have water added to them), they start to melt a little bit.As they rise, gas molecules in the magma come out of solution and form bubbles and as the bubbles rise they expand.

Answer:

Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. Earth has a layered structure that consists of the inner core, outer core, mantle, and crust. Much of the planet’s mantle consists of magma. This magma can push through holes or cracks in the crust, causing a volcanic eruption. When magma flows or erupts onto Earth’s surface, it is called lava.

<h2>Answer:</h2>

More people require more resources, which means that as the population increases, the Earth's resources deplete more rapidly. The result of this depletion is deforestation and loss of biodiversity as humans strip the Earth of resources to accommodate rising population numbers.

Sphinxa [80]

Answer:

Continental climate is a type of climate characterized by consistently hot summers, persistently frosty winters and low rainfall. The continental climate is formed as a result of the prevailing impact on the atmosphere of large land masses. This type of climate is typical for the interior regions of the continents.

The continental climate is dominant in a significant part of the territory of Russia, Ukraine, Kazakhstan, Uzbekistan, Mongolia and the interior regions of the United States and Canada. It leads to the formation of steppes and deserts, since most of the moisture of the seas and oceans does not reach the inland regions.
