Convergent Boundary

Age of the Crust: Old

Convergent Boundary

Fault Type: Reverse

Trasform Boundary

Fault Type: strike slip

Divergent Boundary

Features: ridges, fracture zone

Convergent Boundary

Features: trenches, volcanic island arcs

Hot Spots

Rock Types: bassalt, gabbro

Metamorphic Rock

The broad tundra plains of Northern Canada expose gray, massive rock that formed many kilometers below a mountain belt. This rock exposed only after the overlying rock was away

Convergent Boundary

Volcano Hazards: ash, landslide, lava flow

Convergent Boundary

Volcano Shape: Cone

Hot Spots

Volcano Shape: wide/flat

Aquifer

a body of permeable rock that can contain or transmit groundwater.

Porosity

a measure of how much of a rock is open space

liquefaction

a phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other rapid loading.

Aquitard

a zone within the earth that restricts the flow of groundwater from one aquifer to another.

viscosity

ability to flow

Sedimentary Rock

along the coast, waves carry sand out into deeper, quieter water, where it accumulates and gradually becomes buried. A rock formed from sand grains cemented together

Surface Wave

causes the most destruction

sediment

consists of loose grains deprived from fragmented rock, shell fragments of mineral crystals

fine-grained

cooled fast no chance for crystals to be visible

coarse- grained

formed under the surface allowing crystals to grow

Sedimentary Rock

forms at to near the earths surface by compaction, cementation, and accumulation

intrusive

inside

Saturated Zone

is the area in an aquifer, below the water table

Unsaturated Zone

is the portion of the subsurface above the groundwater table

extrusive

outside

focus

point beneath surface where earthquake occurs

epicenter

point on surface where earthquake occurs

Well Sorted

sediments are composed primarily of grain that are similar

Poorly Sorted

sediments are usually composed of well-rounded grains because the grains have been abraded and rounded during transport

Water Table

the level below which the ground is saturated with water.

Permeability

the state or quality of a material or membrane that causes it to allow liquids or gases to pass through it.

Groundwater

water held underground in the soil or in pores and crevices in rock.

Convergent Boundary

Rocks: rhyolite, granite, obsidian, pumice

Primary Wave

fastest wave

Divergent Boundary

fault type- normal

magma

molten rock below the surface

lava

molten rock breaking the surface
