G11 BONIFACIO Earth and Life Science Quiz

Where does the Earth's internal heat primarily come from?

• Solar radiation

• Radioactive decay

• Ocean currents

• Atmospheric pressure

Which of the following is NOT a source of Earth's internal heat?

• Radioactive decay

• Solar radiation

• Residual heat from Earth's formation

• Friction from tectonic plates

Magma is formed when:

• Rocks freeze due to low temperature and high pressure

• Rocks melt due to high temperature and low pressure

• Rocks are compressed without heat

• Rocks are exposed to sunlight and exposed to air

Which condition favors magma formation?

• Low temperature and high pressure

• High temperature and low pressure

• Low pressure and low temperature

• High pressure and low temperature

Where is magma mostly found?

• In the atmosphere

• Beneath Earth's crust

• On the ocean surface

• In glaciers

What is plutonism?

• Magma cooling on the surface

• Magma cooling beneath the surface

• Magma erupting from a volcano

• Magma forming sedimentary rocks

Volcanism refers to:

• The movement of tectonic plates

• The eruption of magma onto the surface

• The cooling of magma underground

• The formation of metamorphic rocks

Plutonic rocks are formed from magma that cools:

• Quickly on the surface

• Slowly beneath the Earth's surface

• In the ocean

• In the atmosphere

What happens to magma after it reaches the surface?

• It forms sedimentary rocks

• It evaporates

• It cools and solidifies into extrusive igneous rocks

• It becomes metamorphic rock

Metamorphism involves changes in:

• Color only

• Mineral composition and texture

• Size of the rock

• Location of the rock
