Rocks

There are many kinds of rocks. They come in

a great variety of shapes, sizes, colors, and

textures. Rocks also have some things in

common. They are made naturally and are

made of smaller particles and minerals that are

stuck together. They are made of

specific chemicals. What do rocks have in common?

a. They are all the same sizeb. They are all the same colorc. They are made naturallyd. They are the same shape

Factories use different processes to make

things. They use heat, water, and force from

machines to form their products. Earth is like

a giant rock factory. Wherever you are right

now, if you could dig down far enough, you

would find rocks being made deep inside the

earth. 2. How is the Earth like a factory?a. They both have machinesb. They both use the same processc. They both make rocksd. They both make things

Rocks can be divided into three rock types.

They are igneous, sedimentary, and

metamorphic. The groups describe how they

are made.

3. Rocks are divided into which three groups?a. igneous, sediment, metamophoseb. sedimentary, igneous, metamorphicc. ignite, metamorphic, sedimentd. sedimentary, ignite, metamorphic

Igneous

• The texture depends on how fast the rock cools– Quickly cools- smooth texture

– Slowly cools- bumpy or rough texture

•These rocks were made from cooled magma or lava

•Igneous literally means “From Fire”http://www.learner.org/interactives/rockcycle/change2.html

Sedimentary

• They are soft and crumbly, made of layers

• Examples are sandstone, limestone and shale

These rocks are made from layers of sediment that has been cemented together

Types of sediment:

sand, shells, pebbles, bits of rock, minerals, organic matter (from living things), or fossils

http://www.learner.org/interactives/rockcycle/change3.html

Metamorphic• Metamorphic rocks are formed

when existing igneous or sedimentary comes under extreme heat and or pressure (“squeezing”).

• Examples are Marble, and Slate

Two groups based on internal structure:

foliate- bands or zones of same material

Non-foliated- no visible bands or zones

http://www.learner.org/interactives/rockcycle/change.html

Metamorphic

• These rocks have literally “Metamorphosed” (changed).

• That means they started out as one thing and became something completely different.

• They are formed underneath the surface of earth

• TSW understand the evidence that shows the Earth has changed over geologic time (including the types of rocks, the rock cycle, minerals, and fossil record).
