What is plate tectonics?
This type of rock is created when molten lava cools and solidifies on Earth's surface or underground.
What is igneous rock?
Sandstone and limestone are examples of this rock type, which forms from compressed layers of deposited material.

What is metamorphic rock?
This term encompasses all the water on a planet, including oceans, rivers, glaciers, and groundwater.
What is the hydrosphere?
This natural phenomenon occurs when atmospheric gases trap heat radiating from Earth's surface, keeping the planet warm enough to sustain life.
