Metamorphic Rocks

Slate: Slate is a foliated metamorphic rock that is formed through the metamorphism of shale. It is a low grade metamorphic rock that splits into thin and tiny pieces.

common use: roofing slate...for roofing.

Marble: Marble is a non-foliated metamorphic rock that is produced from the metamorphism of limestone. It is composed of calcium carbonate.

common use: counter tops or carvings and sculptures

Quartzite: Quartzite is a non-foliated metamorphic rock that is produced by the metamorphism of sandstone. It is composed of quartz.

common use: flooring or even in fire places or walling.

Igneous Rocks

http://geology.com/rocks/igneous-rocks.shtml - igneous rocks

Granite: This Igneous rock can be used to make counter tops it is a building stone. It is intrusive and is a felsic type of rock.

Basalt: Basalt is an extrusive igneous rock. Crushed basalt is used for railroad ballast.

Gypsum:Processed gypsum is used in industrial or building plaster, prefabricated wallboard, cement manufacture, and for agriculture.

Graphite:Graphite is the crystal form of carbon. It is used as a dry lubricant and steel hardener and for brake linings and the production of "lead" in pencils.

Copper:Copper is used in electric cables and wires, switches, plumbing; heating, electrical, and roofing materials; electronic components; industrial machinery and equipment; transportation; consumer and general products; coins; and jewelry.

Canada

pros:

-it helps the environment

-we will have green energy.

-better for the air

cons:

-its very expensive

-it affects shoreline property values.

-turbines are ugly

My opinion is that Canada should go through with this because it is helping us with the environment. It may cost a ton of money but there helping us too. The view and the fishing business is not really that big of a deal because we can import seafood and fish from other places or buy it at the grocery store. People can get used to the view also, even though it will bring down property value. We need clean air to live and to have nature as well.

We could protest against this. We can even talk to Canada about the cause and effects of installing turbines. We could convince them to wait a while and see what happens first as well.

earthquakes&volcanoes
Is there also a relationship between the plate boundaries of Earth and volcanoes? Yes there is. Were some volcanoes are on the map there are some earthquakes too. For example there are earthquakes and volcanoes all along the west coast on the whole North American continent.

Cascades Volcanoes:Continent-continent convergent boundary
San Andreas Fault Zone:Ocean-continent convergent boundary

Plate Tectonics

The breakup of Pangea was 225 million years ago. The continental breakup that almost happened in Michigan occurred 1.1 billion years ago. The kind of rock that now fills the Keweenawan Rift is basalt. This happened during the Early Carboniferous period, 356 million years ago, Michigan was on the Equator at the time. The Mediterranean Mountains will be north of Africa in the future world. They say in 250 million years North America will be joined with South America and Africa.

clouds.

Mammatus clouds are very harmless.

Lenticular clouds they are seen by mountains or hills.

Roll clouds caused by thunderstorms.

Noctilucent clouds form by sunsets.
