earths outermost layers
atmosphere-78nitrogin&21oxygen

biosphere-where life exists
Earth's Internal Structure
from the outside, in:
crust- (continental and oceanic )outermost layer. mantle-surrounds core(silicate rocks, iron, magnesium
core- central mass of the earth
Earth's Layers are based on what physical properties
lithosphere-rock sphere
asthenosphere-hot and plastic upper mantle where temp and pressure are very high
mesosphere- region between asthenosphere and core, hot and rocky
outer core- hot liquid iron core where earth's magnetic field is produced
inner core-hot solid core where earth's magnetic field is produced liquid iron and it spins with the earth
Earth's continents have 3 major structural components
1. shields (basement complex)
2. stable platforms
3. folded mountain belts
Structural components are?
1.shields
2.stable platforms
3.folded mountain belts
1. flat region of a continent of crystalline rocks (igneous and metamorphic rock)
2.sedimentary rocks cover the shield or basement complex
3. a long linear zone in the earth's crust where the rocks have been intensely deformed by horizontal stress during the slow collision between two lithospheric plates and been intruded by molten rock
Tectonics
branch of geology dealing with mountain building effects on regional scale
Lithosphere plates of the earth and what do they do
1.divergent boundary, where 2 plates move apart in the ocean
2.convergent boundary, where 2 plates come together
3. transform boundary, where plates slide past each other and produces fault lines
convergent boundaries are?
1.continental to ocean crust
(tsunamis and earthquakes and creates subduction zone)
2.oceanic to oceanic crust (produces volcanoes in the ocean)
3.continent to continent (produces mountains)
Minerals, what are they?
they are naturally occuring, inorganic, solid, with a definite internal structure and the chemical composition varies within a range, definite physical properties based on the composition and its internal structure, its stable over a specific range of temperatures and pressures
Minerals, what are they made up of?
ions and bonded particles,which determines the physical properties of the mineral
Minerals, physical properties?
determined by planes of structure of weak and strong bonds
Minerals internal structure produces the physical properties, what are they?
1.crystal form
2.cleavage
3.luster
4.hardness
5.color
6.streak
7.density
Definition Of:
1.crystal form
2.cleavage
3.luster
4.hardness
5.color
6.streak
7.density
1. specific geometric shape produced when a mineral crystal grows in an unrestricted environment.
2.the tendency of a crystal to split or break along smooth planes parallel to the zones of weaker bonds in the crystal structure.
3.the appearance of the mineral in reflected light.
4.the resistence to abrasion and is measured on Moh's scale
5.the most common property to identify minerals and the least reliable.
6.the color of the powdered mineral when ground up
7.the ratio of a minerals weight to its volume.
