Types of Rocks
The thickest layer of the Earth, made of molten rock:
What is the mantle?
This plate boundary ALWAYS causes earthquakes.
What is transform boundary?
What are sedimentary rocks?
Rocks made from compressed and cemented sediment.
The movement of soil by gravity, wind, and running water
What is erosion?
The slow movement of Earth's landmasses riding on tectonic plates.
Scientists use these imprints in rocks to provide information about life and conditions of the past.
What are: fossils?
A rock that has changed from one type of rock to another by heat or pressure; may also have a swirled look, or layers
What is a metamorphic rock?
When sediment is dropped off, or collects in an area
What is: deposition?
This increases as the depth beneath the surface of the Earth increases.
What is: heat and/or pressure?
The type of boundary formed where two tectonic plates come together
What is a convergent boundary?
Rocks are never created or destroyed, they _____________________.
change form
The way trenches, mid-ocean ridges, and mountain ranges are formed
What is plate movement or plate tectonics?
This is how a sedimentary rock or igneous rock can be changed into a metamorphic rock.
What are: heat and pressure?
This causes the movement of the mantle?
What is: heat energy or convention currents?
When the tectonic plates of the Earth slip or slide past each other horizontally, this boundary is formed.
What is a transform or slip/slide boundary?
