convergent plate boundary
plates push towards each other, one goes under the other
volcanoes, earthquakes
divergent plate boundary
plates push away from each other
ridges, volcanoes, sea floor spreading, earthquakes sometimes
transform/strike-slip plate boundary
plates slide past each other
shallow, frequent earthquakes
sheet soil erosion
surface removed into water
plants help
rill soil erosion
small channels of water cause soil to flow into water
still cropping or less till help
gully soil erosion
wider cuts from expanded rill cause soil to flow into water
diverting water away from rill/gully helps
soil is composed of...
sand, silt, and clay
percolation
movement of water into ground
infiltration
movement of ions or chemicals through percolation
layers of atmosphere(top to bottom)
exosphere, thermosphere, mesosphere, stratosphere, troposphere
air is most dense in the...
troposphere
the ozone layer is located in the...
stratosphere
air circulates in part due to...
earth's rotation
coriolis effect
rotation of earth deflects wind
intensity of solar radiation is determined by...
the angle of the sun's rays
insolation(incoming solar radiation)
solar radiation ÷ area
solar radiance
concentration of solar energy
latitudes perpendicular to solar radiation receive ____ intensity
most
axial tilt causes...
seasons
rain shadow
region of dry land that's dry cause a higher elevation area blocks precipitation from it
area closest to water gets it but behind it it's dry
deserts form ___ ° from equator
30°
el niño
winds stall and may reverse: current reverses so no nutrient upwelling resulting in less fish
la niña
conditions intensify: enhanced normal wind, current more intense so more nutrients in upwelling in ocean resulting in more fish
higher sea levels are caused by...
land ice melting and water expanding due to heat
polar regions being affected by climate change
positive feedback loop of less light being reflected to the ground heats up and more is absorbed causing pole warming
melting permafrost
means wet biomass, decomposition, and thus methane released and heated earth: positive feedback loop
marine ecosystems and climate change
new habitats created, deep sea habitat loss, and ocean current changes
