Earth Science Topic 12 Earths Interior Flashcards

Brief Review for Earth Science Topic 12 Earths Interior

1049211594	Original horizontality	Assumes that sedimentary rocks and some igneous rocks form in horizontal layers
1049211595	Folded	Rock layers are bent or curved
1049211596	Faulted	Rock layers are offset or displaced along a crack
1049211597	Uplifted	Reason why we find fossils hundreds to thousands of meters above sea level
1049211598	Earthquake	Natural rapid shaking of the lithosphere
1049211599	Seismic waves	Waves that come out from an earthquake
1049211600	Epicenter	Location on land or water surface directly above Earthquake focus
1049211601	P waves	Earthquake waves that vibrate in the direction the wave is moving
1049211602	S waves	Earthquake waves that vibrate at right angles to the direction the wave is moving
1049211603	Tsunami	Large wavelength ocean wave that is produced by an Earthquake or landslide
1049211604	Volcano	Mountain composed of extrusive igneous rocks
1049211605	Volcanic eruption	Giving off of gases, lava, and lava rock onto Earth's surface
1049211606	Moho	Seperation between the mantle and the crust
1049211607	Lithosphere	Crust and the upper portion of the mantle
1049211608	Asthenosphere	Plastic-like portion of the mantle
1049211609	Plate tectonics	Concept that Earth's lithosphere is broken up into plates
1049211610	Divergent plate boundary	Where two plates separate and magma rises to fill the separation, usually at mid-ocean ridges
1049211611	Convergent plate boundary	Where two plates collide
1049211612	Subduction	Where oceanic crust below continental crust because of its higher density
1049211613	Transform plate boundary	Where two plates slide past one another
1049211614	Hot spot	Volcanic activity in the middle of plates, how the Hawaiian Islands were formed
