a
elements combine due to high pressure

b
water solidifies due to drop in temperature

c
atoms break up after a chemical reaction

d
magma cools after a volcanic eruption

Answer 1

Explanation:

ANSWER:-

D. Magma cools after a volcanic eruption.

Reason-

• Magma is the liquid state of the lava, which erupts just after volcanic eruption.
• Volcanoes create Magma which is in the 2nd layer of Earth. Just below the solid lair.
• Now, this magma consists of many minerals which cools down and gives out minerals.
• These minerals are often stored in the Lithosphere itself.
• Next, as it contains many minerals it gets crystallized and forms into minerals like Basalt.
• These volcanic eruptions also affect the soil. In some places like Deccan Plateau Volcanic Activities have lead to formation of black soil.
• So, it is the first and foremost step in formation of minerals.
