Q: Plate Tectonics, Minerals and Rock Cycle

Front

What is the definition of hardness in minerals?

Back

Hardness is a mineral's resistance to being scratched.

Front

What process transforms igneous rock into sedimentary rock?

Back

Weathering and erosion wear away igneous rock, forming particles that eventually cement into sedimentary rock.

Front

What type of igneous rock is known for being smooth and glassy?

Back

Obsidian is a type of igneous rock that is smooth and glassy.

Front

Where do sedimentary rocks like sandstone typically form?

Back

Sedimentary rocks such as sandstone often form at the bottom of bodies of water.

Front

What type of rock is granite?

Back

Granite is an igneous rock.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation and transformation, including igneous, sedimentary, and metamorphic rocks.

Front

What is the main characteristic of sedimentary rocks?

Back

Sedimentary rocks are often formed from particles of other rocks and organic materials, and they may contain fossils.

Front

What is cleavage in minerals?

Back

Cleavage is the tendency of a mineral to break along flat surfaces.

Front

What is the difference between magma and lava?

Back

Magma is molten rock beneath the Earth's surface, while lava is magma that has erupted onto the surface.

Front

What is the definition of metamorphic rock?

Back

Metamorphic rock is formed from existing rock that has been changed by heat, pressure, or chemical processes.
