Question

Molten rock inside the earth__________.
A. Magma
B. Lava
C. Topsoil
D. Subsoil

Answer 1

Hint: It is the semi-molten mass that forms igneous rocks on solicitation. It is present in the mantle portion of the earth's layer. Granite stone is formed by its solidification.

Complete answer:
Let us look at the options and discuss the solution.
Option A. Magma is a super hot fluid and semi-fluid stone situated under Earth's surface. Earth has a layered structure that comprises the inner core, external core, mantle, and crust. A significant part of the planet's mantle comprises magma.

Option B. At the point when magma streams or emits onto Earth's surface, it is called lava.

Option C. Topsoil is the upper layer of soil, normally between 2 to 8 crawls top to bottom, that contains the majority of the ground's supplements and fruitfulness.

Option D. Subsoil is the soil underneath the surface soil (dirt). Worn and climate beat, this disintegrated material is a notable piece of the climate.

Hence the correct answer is Option A.

Additional Information:
-Magma creates inside the mantle or hull when the temperature-pressure conditions favor the liquid state. Magma ascends toward the Earth's surface when it is less thick than the encompassing stone and when an underlying zone permits development.
-Magma creates or gathers in zones called magma chambers. Magma can stay in a chamber until it cools and solidifies framing molten stone, it emits as a well of lava, or moves into another magma chamber.

Note: - At the point when magma becomes strong, it's for the most part by cooling gradually, far underneath the surface. This makes "plutonic" shakes, for example, stone.
-Magma cools all the more rapidly, and structures different sorts of rock, for example, basalt.
-Like strong stone, magma is a combination of minerals. It additionally contains limited quantities of broken up gases, for example, water fume, carbon dioxide, and sulfur.
-The high temperatures and weight under Earth's outside layer keep magma in its liquid state.
