What are the three main types of rocks?

Igneous, Sedimentary, and Metamorphic.

How are igneous rocks formed?

They are formed from the solidification of molten magma or lava.

What is the process of sedimentation?

The accumulation and compaction of mineral and organic particles.

What causes metamorphic rocks to form?

Heat, pressure, or chemically active fluids alter existing rock types.

What does the rock cycle illustrate?

The continuous process of rock formation and transformation.

What is weathering and erosion?

The breakdown of rocks at the earth's surface.

What happens during the metamorphism process?

Rocks are transformed under heat and pressure.

What is melting in the rock cycle?

The formation of magma from heated rock.

What is the definition of solidification?

The cooling of magma to form igneous rock.

What is kinetic energy?

The energy of motion.

What is potential energy?

Stored energy based on position.

What is thermal energy?

Energy related to the temperature of an object.

What type of energy is stored in chemical bonds?

Chemical energy.

What is nuclear energy?

Energy stored in the nucleus of atoms.

How is electrical energy generated?

From the movement of electrons.

What consists of both potential and kinetic energy?

Mechanical energy.

What does the Law of Conservation of Energy state?

Energy cannot be created or destroyed, only transformed.

What distinguishes renewable from non-renewable energy?

Renewable energy can be replenished naturally; non-renewable energy is finite and cannot be replaced.

Give examples of renewable energy sources.

Solar, wind, and hydroelectric energy.

Give examples of non-renewable energy sources.

Fossil fuels and nuclear energy.
