Question

2. Describe the movement of magma in the mantle for class
6 cbse board.
​

Answer 1

Answer:

magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.

Explanation:

Answer 2

Answer:

• Magma is described as the extremely hot liquid or the semi-liquid rock which is situated under the Earth's surface. This magma can easily push through the holes or the cracks in the crust surface which causes a volcanic eruption. When the magma flows or it erupts onto the Earth's surface, this is given a new name called lava. Like a solid rock that has many constituents, magma is also a mixture of many minerals.

This is a molten or semi-molten material that is of course naturally produced. They also form the igneous rocks in this process. In another study, it is proved that the magma which is found underneath the earth’s surface has magmatism that is similar to be found on other terrestrial planets and other natural satellites. Apart from molten rock, this magma may also contain suspended crystals and gas bubbles.
