Good Morning!!! Take out your Mineral Foldable and your Rock Flipbook that we worked on this week and are due TODAY!!! Take out a sheet of paper, tear.

Good Morning!!!

• Take out your Mineral Foldable and your Rock Flipbook that we worked on this week and are due TODAY!!!

• Take out a sheet of paper, tear it in half and share it with a friend!!! We are taking a quiz!!!

1

Quiz 4/4/14

• 1. Name three of the characteristics of a mineral that we learned about while creating the foldable!

• 2. Name the three main types of rocks

2

Minerals and Rocks

• Minerals – naturally occurring, inorganic substance (no carbon!)

• Rocks - The solid mineral material forming part of the surface of the earth and other similar planets, exposed on the surface or underlying the soil or oceans

3

The Rock CycleThe Relationships among the major

rock groups

IgneousRocks

– Formed from magma cooling(molten rock)2 types - – Plutonic (intrusive – formed inside the

earth’s crust) – slow cooling and crystallization (large

crystals):

– Volcanic (extrusion – erupted out of the earth’s crust): quick cooling at the surface (Small Grains/crystals)

5

Sedimentary Rocks

– Weathering can occur from water, cold and warm temperatures, wind, glaciers

– There is also chemical weathering

6

Sedimentary rocks are formed at the Earth’s surface by these 4 steps:

Weathering

Erosion

Deposition

Cementation

Metamorphic Rocks

• Were once sedimentary or igneous rock• Changed by high pressure and/or high temperatures• Temperatures cannot be high enough to cause melting or these rocks will be considered

igneous

• The rock cycle demonstrates the relationships among the three major rock groups

• It is powered by the interior heat of the Earth

• As well as earth’s momentum and…

• The energy from the sun

• It involves processes on the Earth’s surface as well as the Earth’s interior

• It connects the “hydrologic cycle” with the “tectonic cycle”.

In Conclusion…
