good morning!!! take out your mineral foldable and your rock flipbook that we worked on this week...
TRANSCRIPT
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
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…
