What is a rock made from heat and pressure but not from melting
metamorphic
200
The removal of soil by gravity, wind, and running water
Erosion
200
What is the hottest layer?
Inner Core
200
What are two common effects of plate movements?
Earthquakes and volcanoes
200
Scientists use these to provide information about life and conditions of the past.
What are: fossils?
300
When sediments are compacted and cemented together over long periods of time they form these.
Sedimentary rocks
300
The steps needed to turn into an igneous rock.
melting in the mantle, cooling in or on the crust
300
What is the core mostly made of?
iron and nickle
300
The type of boundary formed where two tectonic plates come together
What is a convergent boundary?
300
Fossils are usually found in this type of rock.
What is: sedimentary rock?
400
Rocks that are usually found near volcanoes and are formed from the cooling and hardening of hot magma or lava
Igneous Rocks
400
Steps needed to become a sedimentary rock
weathering, erosion, compacting, and cementation
400
The 4 main layers of the Earth from outside to inside
What are: 1. crust; 2. mantle; 3. outer core; 4. inner core?
400
The type of boundary formed when tectonic plates move apart
What is a divergent boundary?
400
Name a common fossil that scientists would find in an area that use to be an ocean.
shells (fish skeletons or shark teeth are acceptable)
500
The addition of these is needed over time for a sedimentary rock to be changed into a metamorphic rock.
What are: heat and pressure?
500
When rocks change from one form to another and back again over many years
What is the rock cycle?
500
What is the thinnest layer?
The Crust
500
When the tectonic plates of the Earth slip or slide past each other horizontally, this boundary is formed.
What is a transform fault boundary?
500
