Geologists have found fossils of sea animals on the Himalayas. How do you think these fossils came to be on the Himalayas?

• Because the Himalayas were once under the sea and rose up due to tectonic movements.

• Because sea animals migrated to the mountains.

• Because the fossils were carried there by humans.

• Because of volcanic eruptions that brought sea animals to the surface.

Refer to the diagram 'Structure of the Volcano'. Which part of the volcano is responsible for storing molten rock before it erupts?

• Central vent

• Magma chamber

• Lava

• Earth's crust

The rocks are harder inside than outside because:

• the inside is less exposed to weathering and erosion

• the inside has more minerals

• the outside is older than the inside

• the outside is protected by soil
