Rocks are made of minerals, and they are formed in different ways. According to the diagram above, how are sedimentary rocks formed?

• Molten rock cools and turns solid.

• Wastes deposited by plants and animals decompose and weather.

• Other rocks experience intense heat and pressure.

• Sand and other particles are buried, compacted, and cemented together.

This layer is the innermost layer of the Earth.

• Crust

• Mantle

• Outer Core

• Inner Core

This layer is a solid ball of metal.

• Crust

• Mantle

• Outer Core

• Inner Core

Which layer of Earth is solid and why?

• The inner core is solid because of movement of the outer core.

• The inner core is solid because of the freezing temperatures.

• The inner core is solid because of the extreme pressure from the other layers.

• The outer core is solid because of the extreme pressure from the other layers.
