Define weathering
Break down of rocks into smaller pieces.
How sedimentary rocks are formed?
formed as layers of sediment that are pressed together and harden.

Luster
Streak
Hardness
Mention the three states of matter
Solid
Liquid
Gas
Define volume
It is the amount of space taken up by matter.
Define erosion
Is the movement of sediments from one place to another
Define an igneous rock
A type rock that is formed when magma cools and hardens.
Define luster
The way a mineral surface reflects light
Define mass
It is the amount of matter in an object.
Mention the three types of sedimentary rocks
Limestone
Sandstone
Mudstone
Define deposition
The laying down of material (pieces of rocks or sediments)
How metamorphic rocks are formed?
They are formed when heat and pressure change other rocks
Define streak
Color powder a minerl leaves when its scratched
What is a mixture?

External factors of an igneous rock
Cools and hardens
water
ice
gravity
wind
Metamorphic rocks can be formed by two metamorphic, true or false?
true
Why minerals are considered to be inorganic
Because they do not come from a living things
What is a solution?
The combination of two or more substances that are chemically combined
Define density
It is the amount of mass in a given volume of matter
Describe the differences between physical and chemical weathering
Physical: The size of rocks is changed
Chemical: the material of rocks and soil CHANGE.
