Igneous and Metamorphic Rocks: Magma and Lava

Molten rock, known as magma, originates deep within the Earth due to high temperatures and pressure. It is less dense than surrounding rocks, allowing it to rise. When it reaches the surface, it is called lava. Magma can also interact with water, creating geysers and hot springs.

Where does molten rock, or magma, originate from?

• The Earth's surface

• Deep within the Earth

• The ocean floor

• The atmosphere

What happens to magma when it reaches the Earth's surface?

• It becomes solid rock

• It evaporates

• It turns into water

• It is called lava

What is the term for molten rock on the Earth's surface?

• Basalt

• Sediment

What can happen when magma comes into contact with water below the surface?

• It cools down immediately

• It forms geysers and hot springs

• It causes earthquakes

• It solidifies into rock

What is the result of superheated water rising to the surface?

• Formation of volcanoes

• Creation of hot springs and geysers
