Plate Tectonics
This hazard can be caused by seismic activity or an undersea volcanic eruption
What is a tsunami?
List the three mineral particles that make up soil, from smallest to largest
What are clay, silt, and sand?
This is what ITCZ stands for
What is the intertropical convergence zone?
This ocean has only one circulatory gyre, and it is found in this hemisphere
What is the Indian Ocean, in the Southern hemisphere?
Soil degradation, caused primarily by loss of topsoil, is driven by this human activity
What is agriculture?
What is plowing and tilling?
This is described as a plume of hot magma rising to the surface from the mantle, where it interacts with tectonic plates
What is a hot spot?
A soil sample is composed of 30% silt and 15% clay. This is how much of the sample should be composed of sand.
What is 55%?
Descending warm, dry air on the poleward boundaries of these cells create ideal conditions for desert biomes to form
What are Hadley cells?
Cold currents (moving from the poles toward the equator) are found on this side of circulatory gyres
What is the east side of the gyre?
This atmospheric circulatory cell has westerly winds at the surface
What is the Ferrel cell?
Seafloor spreading occurs at this type of boundary, often located in the center of the ocean floor
What is a divergent boundary?
Base saturation is an expression of the proportion of soil bases to soil acids. Plant growth is improved when base saturation is...
What is high?
Surface winds are easterly in these two circulatory cells
What are the Hadley and Polar cells?
This side of a mountain will be warm and dry, due to the rain shadow effect
What is the leeward side?
The side of a mountain facing onshore winds will be lush with vegetation and experience high precipitation, and is called this
What is the windward side?
This plate boundary does not create volcanoes, and is instead known for producing potentially powerful earthquakes along fault lines
What is a transform boundary?
Cation exchange capacity, or CEC, determines the ability of a soil to absorb and release nutrients. This is controlled by the amount of _____ present in the soil.
What is clay?
In the southern hemisphere, the Coriolis force causes deflections in this direction
What is to the LEFT?
Right in NH
Cardinal directions should be avoided - that depends on the original direction of motion
This characteristic of upwelling ocean water makes it ideal as a location for commercial fishing operations
What is the nutrient level of the water?
In the northern hemisphere, the Coriolis force causes deflections in this direction
What is to the RIGHT?
Left in SH
Cardinal directions should be avoided - that depends on the original direction of motion
There are three different types of convergent plate boundaries. This one results in the creation of a volcanic island arc.
What is a an oceanic-oceanic convergence zone?
Permeability and water holding capacity have this type of relationship.
What is inverse?
When one is low the other is high, and vice versa.
This type of feedback loop occurs because a warmer atmosphere can hold more water vapor, which in turn makes the atmosphere warmer
What is a positive feedback loop?
Dense, cold water sinks in the northern part of this ocean as part of the global thermohaline circulation
What is the Atlantic Ocean?
This process causes the edge of an oceanic plate to move downward beneath a continental plate, where it melts under high pressures and temperatures
What is subduction?
