Terms 1
What is the lithosphere?
made of melted iron and nickel, flows like a liquid, creates Earth's magnetic field
What is the outer core?
a mixture of elements
What is a rock?
forms when conditions cause sediment to melt together
What is sedimentary rock?
the order of Earth's layers, from centre to the outermost
What is inner core, outer core, mantle, and crust?
The liquid area of the mantle
1800 miles thick, moves slowly, contains convection currents
What is the mantle?
they make up rocks
What are elements?
forms when existing rock is heated to extreme temperatures and is under enormous pressure
What is metamorphic rock?
this rock has obvious layers
What is Sedimentary Rock?
The amount of matter in a certain space
What is density?
large, swirling forces of matter caused by different densities of hot and cold matter
What are convection currents?
the process that changes rock from one kind to another
What is the Rock Cycle?
forms when magma hardens
What is Igneous Rock?
This rock has no obvious layers
What is Igneous Rock?
The tendency of matter to attract other matter
What is gravity?
happens when rain, snow, or ice causes rock to break down or break apart
What is weathering?
When sediment reaches its final resting place
What is deposition?
What is, the plates on top of it move?
the layers of this rock are distorted, indicating it has been under extreme heat and pressure
What is Metamorphic Rock?
made of solid iron and nickel, bears the weight of the entire Earth
What is the inner core?
little crumbs of broken rock
What is sediment?
When water flows downhill or wind blows dust around (how rock gets from one place to another)
What is erosion?
happens when rock near the Earth's core warms rises, cools near the mantle, becomes denser, and sinks to the bottom of the mantle
What is a convection current?
when sediment is moved form place to place by erosion from water or wind. The sediment reaches its final resting place and starts to become sedimentary rock
What is, "what happens when sediment goes through erosion and deposition"?
