Question
Determine which of the following statements relating to magma are correct.Magma is a type of metamorphic rockMagma forms when rocks meltWhen magma rises to Earth's surface, it causes a volcanic eruptionWhen magma is deep below the surface, it is referred to as lava
Solution
-
"Magma is a type of metamorphic rock" - This statement is incorrect. Magma is not a type of metamorphic rock. It is actually molten rock that forms beneath the Earth's surface.
-
"Magma forms when rocks melt" - This statement is correct. Magma is formed when the rocks located beneath the Earth's surface are subjected to extreme heat and pressure causing them to melt.
-
"When magma rises to Earth's surface, it causes a volcanic eruption" - This statement is correct. When magma rises to the surface through cracks or weaknesses in the Earth's crust, it causes a volcanic eruption.
-
"When magma is deep below the surface, it is referred to as lava" - This statement is incorrect. Magma is referred to as lava when it reaches the Earth's surface, not when it is deep below the surface.
