The four characteristics of minerals.
What are forms in nature, is a solid, definite chemical composition and crystal structure?
100
This rock forms when molten rock cools and becomes a solid.
What is Igneous rock?
100
Rocks lack these two characteristics of minerals.
What is definite chemical composition and definite chemical structure?
100
Process when sediment is placed in a new location.
What is deposition?
100
The process which weathered particles are picked up and moved from one place to another
What is erosion?
200
Something is considered a solid if it meets these criteria.
What is having a definite shape and volume?
200
These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks.
What is sediment?
200
Difference between magma and lava.
What is Magma forms inside Earth and lava forms at it's surface?
200
Reason why gravity is important for erosion.
What is it moves water and helps move sediment?
200
This type of weathering causes rocks on the beach to be nice, smooth and round.
What is Abrasion?
300
One way you can tell 3 minerals apart that all appeared to be clear and shiny.
What is look at its crystal structure or its chemical composition?
300
2 things that cause metamorphic rocks to form.
What are heat and pressure?
300
This type of igneous rock forms when magma cools inside earth.
What is Intrusive igneous rock?
300
Metamorphic rock becomes this rock when it melts.
What is igneous rock?
300
This process turns magma into igneous rock.
What is cooling?
400
True or false and why: One sample of halite found in the USA had a chemical composition of Nitrogen and Oxygen, another sample of Halite had a chemical composition of Hydrogen and Oxygen.
What is False because all minerals have a definite chemical composition?
400
Molten rock that reaches Earth's surface.
What is extrusive igneous rock?
400
When igneous rock wears away it becomes this type of rock.
What is sedimentary rock?
400
Reason why a larger rock would weather quicker than a smaller rock.
What is there would be more rock exposed to weathering effects?
500
This type of minerals is the most common found on earth and are composed of these elements.
What is Silicates that consist of oxygen and silicates?
500
Type of rock that is generally found at the surface of Earth's crust and reason.
What is sedimentary rock because that is where the majority of rock is exposed and formed by compaction of sediment?
500
Place where weathering would occur faster, a tropical zone or dessert and reason.
What is a tropical zone because there is more water and heat?
500
Difference between chemical and mechanical weathering.
What is mechanical weathering does not change the composition of the rock whereas chemical weathering does?
