PLZ PLZPLZCan u peeps answer these 11 q?PLZ PLZPLZ i need help with them they r hard!PLZ PLZPLZ?

List some examples of “geological processes”
-erosion

Know all the layers of the Earth.
-Inner core
-Outer core
-mantle
-Crust


if you have any more question, my yahoo is on my profile :)
Which layer of the earth contains the crust?
-The outer layer

Know the Theory of Continental Drift.
-The continental drift theory is the theory that once all the continents were joined in a super-continent, which scientists call Pangaea. Over a vast period of time, the continents drifted apart to their current locations

Review the Theory of Plate Tectonics
-The lithosphere is broken up into what are called tectonic plates. In the case of Earth, there are currently seven to eight major (depending on how they are defined) and many minor plates. The lithospheric plates ride on the asthenosphere. These plates move in relation to one another at one of three types of plate boundaries: convergent, or collisional boundaries; divergent boundaries, also called spreading centers; and transform boundaries. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along plate boundaries

Know the 3 types of Volcanoes and how they are formed
-Composite cone - It is a cone shaped mountain with steep, smooth, barren slopes often with a single plume of smoke emitted from a single central vent. It is composed of alternating layers or strata of material created by pyroclastic (lava) flows. Liquid magma is emitted from a reservoir deep in the earth's crust.
-Shield Volcano - The shape of this type of volcano is more like a dome than a tall cone. This type of volcano is built slowly and can have multiple vents producing lava flows.
-Cone Volcano - A cone structure built by an accumulation of loose bits of magma called scoria that fall around a vent or crater after being expelled during moderately explosive activity.

They are the simplest of volcano structures and are prevalent in Western North America and elsewhere in the world.

What kind of mountains form at convergent boundaries?
-Composite

What is sea floor spreading and what can result from it?

What is a fault?
-An old plate boundary

How are Earthquakes measured?
On the a Richter scale

What are P-waves, S-waves and L-waves
P-waves - P-waves are type of elastic wave, also called seismic waves, that can travel through gases (such as sounds), elastic solids and liquid
S-waves - A type of seismic wave, the S-wave, secondary wave, or shear wave (sometimes called an elastic S-wave)
L-Waves - ( geophysics ) A phase designation for an earthquake wave that is a surface wave
