Causes of earthquakes at transform plate boundaries
What is stored energy is released from locked plates
What is the tropopause?
Identify our watershed.
What is the Big Sioux River?
Describe upwelling and explain its importance.
What is
Upwelling brings cold deep waters to the surface which contain more oxygen and cause life in the waters to flourish. This helps fishermen to catch more fish.
Identify and describe the plate boundary that can lead to sea floor spreading
What is a divergent plate boundary? Tectonic plates moving away from each other.
Describe why the westerlies blow from the west.
What is
- Ferrel cells cause the winds to blow away from the equator
- Winds near the equator have a faster velocity due to the Earth being thicker in circumference in the middle and therefore are deflected the opposite direction than would be expected in the coriolis effect.
Describe what factor determines the seasons and how they are different in the northern and southern hemispheres.
What is the tilt of the Earth?
Northern hemisphere is tilted most towards the sun in June
Southern hemisphere is tilted most towards the sun in December
Identify conditions that would improve fishing conditions off the west coast of South America.
What is
increased upwelling
La Nina
This boundary type often causes mountain ranges. Describe the boundary.
What is a convergent boundary? Two plates moving towards one another.
What factor drives the hadley, ferrel, and polar cells?
Warm, moist air is less dense and rises. Driven by the sun's radiation.
Describe lake effect snow.
What is warm lake water evaporates and condenses into snow therefore leeward shores have higher snowfall amounts.
Identify the conditions to cause more intense monsoons in SE Asia.
What is La Nina
Hawaii is caused by this tectonic activity. Describe how the islands of Hawaii were formed.
Identify the climates found at 0 and 30 degrees latitudes and explain what phenomenon determines these climates.
0- tropical rainforests
30- deserts
Hadley cell driven by convection of hot, moist air rising, releasing rain at 0 and then cool dry air sinking at 30
Identify three non-point sources of pollution in a watershed.
What is fertilizing lawns, spreading manure, littering, sediments run off from construction etc.
These redistribute heat in the ocean.
What is a gyre?
Identify and describe what activity we would expect at a convergent boundary between two oceanic plates.
What is formation of island arcs
One plate subducts the other, magma rises with the increased pressure forming island arcs on the boundary
Identify and describe the five layers of the atmosphere from closest to the Earth to farthest from the Earth.
Troposphere- weather occurs here
Stratosphere- thickest layer of ozone
Mesosphere- less dense layer, colder
Thermosphere- absorbs xray and UV, northern lights appear here
Exosphere- outermost layer, least atmospheric pressure
Explain why the westward side of the Andes Mountains is a desert.
What is the rainshadow effect due to the Eastern Trade winds and 30 latitudes are deserts
Describe the conditions caused by El Nino.
What is trade winds weaken, then reverse
Warm equatorial current brings heat and precipitation to the Americas
Less upwelling off the South American coast
Cooler and dryer conditions in Australia and SE Asia
High Pressure in W Pacific
Low Pressure in E Pacific
