4.1
A plate boundary found in the ocean, where two tectonic plates move away from one another.
Divergent Plate Boundary
The transport of weathered rock fragments by wind and rain is called...
Erosion
This soil texture holds water the best.
Clay
This is the most abundant gas in the Earth's atmosphere.
Nitrogen
?
Free 100 points
All the land that drains into a specific body of water.
Watershed
Solar intensity is highest here.
The equator.
2 causes of Arctic water to sink deeper.
It is colder and saltier.
Convergent plate boundary
These are the four soil horizons.
O-Horizon, A-Horizon, B-Horizon, C-Horizon
This soil type is the most permeable.
Sand
This is Earth's hottest atmospheric layer.
Thermosphere
Wind traveling east to west in the Pacific Ocean are known as.
Trade winds.
Name 2 factors that affect how much a watershed drains.
More vegetation = more infiltration & groundwater recharge
Greater slope = faster velocity of runoff & more soil erosion
Soil permeability determines runoff vs. infiltration rates
What affects the Earth's seasons?
Orbit of earth around sun & tilt on axis changes angle.
Warm water from this region flows up to the Arctic.
The Gulf of Mexico
The pattern of volcanoes & earthquake zones around the Pacific plate.
The Ring of Fire
Monocropping results in the loss of major elements like Na and Mg, name 2 more.
N, P, or K
This soil texture is the best for growing, and considered the most balanced.
Loam
The layer of Earth's atmosphere where weather occurs.
Troposphere
The Earth's tangential velocity (relative spin) is slowest at the equator.
False
Name one of the two major nutrients, that frequently travel as runoff, cause algae blooms.
Nitrogen and Phosphorus
The proportion of light that is reflected by a surface
Albedo
Pattern of shifting atmospheric pressure & ocean currents in the pacific ocean between South America and Australia/Southeast Asia
El Niño
The most dense of the 2 crusts.
Oceanic
The O-Soil Horizon is O because of this.
organic matter (plant roots, dead leaves, animal waste, etc) on top of soil.
Name 3 of the main nutrients for supporting plant growth.
N, P, K+, Mg2+, Ca2+, Na+
This is Earth's coldest layer, because there are fewer molecules to absorb the sun.
Mesosphere
This process circulates warm air and rain around the equator.
Hadley Cell
Loss of stabilizing root structure causes sediment to be swept away more easily.
These population areas often have low albedo and absorb a lot of sunlight.
Cities (Urban Heat Island)
Name an impact of La Niña
Colder Temperatures
More Hurricanes
Droughts and Wildfires
This process drives the formation of new oceanic crust.
Mantle Convection Currents.
These 2 climate factors affect soil formation the most.
Warmer = faster breakdown of org. matter;
More precip. = more weathering, erosion + deposition
Using the Triangle:
You have a soil that is 30% sand, 20% silt, 50% clay.
Clay
The thickest Ozone Layer is found here.
Stratosphere
This process deflects wind traveling through atm. due to spin of earth.
Coriolis Effect
All watersheds (small or large) end up flowing to this level.
Sea level
This object is very near 100% albedo.
A mirror
Name an impact of El Niño.
Warmer Temperatures
Stronger Storms and Flooding
Droughts in Some Areas
