A solid in which the atoms are arranged in a regular, repeating pattern
What are crystals?
The result of weathering, a complex mixture of organic and inorganic material essential for life on Earth
What is soil?
The name for the original super continent
What is Pangaea?
When glaciers grind over the surface bedrock and leave behind deep scratches in the rock
What are glacial striations?
*triple points* a geological theory that explains earth's landscape and shape due to abrupt, violent, short lived global events resulting in mass extinction and changing landscape.

During this process, new magma forces apart the hardened material and continuously pushes older rock aside

In super explosive eruptions, glass and gases can combine to form dense, super heated clouds that travel down hill at high speed
What are pyroclastic flows?
*double points*the smallest unit of a compound with all the properties of that compound
