1. A cool trip around the rock cycle

2. What is a rock?
A rock is a mixture of such minerals, rock fragments, volcanic glass, organic matter, or other natural materials.
Most rock used for building stone contains one or more common minerals, called rock-forming minerals, such as quartz, feldspar, mica, or calcite
When you look closely, the sparkles you see are individual crystals of minerals.

3. What is the difference between a rock & a mineral?
Minerals are solid, naturally occurring, inorganic, have a fixed composition and are made of one or more elements.
Rocks are made of one or more minerals.

4. Can be formed from solutions
Made of elements
Must be inorganic
Can be made from organic materials
Solid
Can be made of lava/ magma
Made only of compounds
Elements must be chemically bonded
Mixtures made of minerals
Have crystals
Can be
man made
Naturally occurring
Can be formed from solutions

5. Rock Types Igneous Sedimentary Metamorphic
There are three types of rocks
Igneous
Sedimentary
Metamorphic

6. What is the rock cycle?
To show how rocks slowly change through time, scientists have created a model called the rock cycle.
It illustrates the processes that create and change rocks.

7. Rock Cycle Continued
The rock cycle shows the three types of rock— igneous, metamorphic, and sedimentary—and the processes that form them.

8. The Rock Cycle explains how Rocks and Natural Processes are related
weathering
Sedimentary
Metamorphic
Is the rock cycle really this simple, neat and colorful?
(NO)

Igneous

9. What is the law of conservation of matter?
Law of conservation of matter states that matter cannot be created or destroyed.
The changes that take place in the rock cycle never destroy or create matter.
The elements are just redistributed in other forms.
