What form of energy drives the hydrologic cycle, the movement of tectonic plates, and weather
patterns?
Heat Energy

What are the principal repositories of water on Earth?
Oceans
Identify three ways that water moves between repositories.
Evaporation Precipitation Gravity
What role does evaporation play in the hydrologic cycle?
Evaporation helps to make the water form clouds from water vapor and condensation. It helps to
covert the water vapors (its gas form) to wat
How does water move within the oceans? How does it move within glaciers?
Water within the oceans move by currents. Move slowly down a slope or valley under the
influence of gravity.
By what process does the amount of water on Earth change from year to year? What is the magnitude
of this change from year to year?
Evaporation of waters molecules and hydrogen atoms; at converging and diverging plate
boundaries and other sites of volcanism, small amounts
Describe the processes that leads to an ice age. What effect does the formation of large
glaciers have on the hydrologic cycle?
Much of Earth's water becomes locked into ice caps and glaciers. Sea levels drop as water
becomes trapped. Less water is available for eva
What are the differences between ice caps and glaciers?
Ice caps are layers of ice that form at Earth's north and south polar regions. Glaciers are
large bodies of ice that slowly flow down a slo
What factors might cause glaciers to advance from polar areas to more temperate zones?
An increase in temperature may cause the glacier to melt and slide. A greater gravitational
pull could cause the glacier to move down.
How do ocean currents affect local climate?
The movement of surface currents where cold water from the poles are moved to the equator and
back. The warm water causes the coastlines wit
Why do we call groundwater in most areas a "nonrenewable resource"?
Because in most areas it takes too long for groundwater aquifers to recharge once all the water
has been pumped out. Also, once contaminatio
What is the difference between weather and climate? Describe the weather and climate of your
area.
Weather: the state of the atmosphere at a given time and place. Climate: a long-term average of
weather for a given region.
In what ways are air masses like reservoirs of the atmosphere?
Air masses have more or less uniform properties, and each adjacent air masses differ in
physical properties
Why does air pressure vary from place to place?
Altitude, Air masses movement and rotation, Jet stream
What is the jet stream? What is the prevailing direction of the jet stream? How does it
influence your weather?
Jet Stream: a high-altitude stream of fast-moving winds that marks the boundary between the
northern polar cold air mass and the warmer air
How does the atmosphere distribute heat across Earth's surface?
Air moves heat primarily through convection. It picks it up from a place where it is hot and
carries it to cooler places. It also moves "col
If land heats up more quickly than water, what does this tell you about their relative heat
capacities?
The air over land has a higher humidity rate, where it can hold more water than over land.
How is a volcanic eruption part of the "rock cycle"? What other cycles might an eruption
affect?
As the lava oozes down and cools, it creates new rocks and destroys/alters others as it flows
down. The atmospheric cycle and the chemical
Why were igneous rocks Earth's first rocks?
They are formed from hot liquid, and our first creations was from the hot liquid core
What are three main kinds of rocks? How do they form?
Igneous Rocks: the first rock to form on a cooling planet, solidified from hot, molten
material; intrusive or extrusive (volcanic) Sediment
If you were driving past a large road cut through rock, what features might you observe to tell
you its origin?
Color, shape, size, grains (smaller pieces a rock is made up of)
