What is the name of physical evidence of life from the past?
What is Deposition?

What is the most dense layer of the Earth?
The Core
What Era is known as the "Age of Mammals"?

How does a convection current form?
It melts, then rises
Solidifies, then sinks
What rock is molten Earth that is cooled?

How do volcanoes erupt?
Volcanoes erupt when magma (molten rock) and gases build up immense pressure beneath the Earth's surface, forcing them to break through the crust.

What is density?
Density is a measure of how much mass is contained within a given volume.
What is Metamorphic Rock?
Rock that changed forms due to extreme temperature and pressures.

What are the names of the mechanical layers of the Earth?
Lithosphere, Asthenosphere, Mesosphere, Outer Core, and Inner Core
Process where fragments of soil
and rock are broken off from the surface
and carried away.
