To complete this study guide, please go back through your notes in your binder. Your notes, exit tickets, labs, and
homework sheets will help you to complete this study guide as well as help you to prepare for our test! This study
guide is meant to GUIDE you back through ALL that we’ve learned this unit.
Due: _____________ Unit 5 DOK 1: ___________________
1.
Fill in the missing information below for the cause/effect chart. USE YOUR OWN WORDS!!!!
Cause
Effect
When there are differences in air pressure, air will move from
areas of high pressure to areas of low pressure. This will
create…
Wind
In warmer areas, the air is less dense and it rises.
Low Pressure
In cooler areas, the air is more dense and it sinks.
High Pressure
2. Fill in the missing information from the chart below. You may write, or draw a specific example; however, it
must be DIFFERENT than the ones from your notes.
Type of Heat Transfer
Radiation
Conduction
Definition
Can travel through…
Energy that can transfer by
traveling in waves. This form of
energy can also travel through
empty space.
Empty space
Heat transfer by direct, physical
touch.
(solid, liquid, gas, empty space)
Solid, liquid, gas
Liquid, gas
Convection
When warm fluids (liquid or gas)
rise and cool fluids sink.
Specific Example
The Sun is an example of
radiation.
Air molecules touching
the Earth’s heated
surface.
Air molecules that touch
Earth’s warm surface will
rise. As they rise higher in
the Troposphere they will
cool down and sink.
3. Describe how convection currents move heat through the ocean. (You MUST use the following words: equator,
warm water, cool water, direct sunlight, indirect sunlight, rising, sinking, more dense, less dense)
Water is warmed at the equator because it receives the most direct sunlight, and the poles receive indirect
sunlight. The warm water from the equator rises to the poles because warm water is less dense than cool water.
At the poles, the cool water sinks back down to the equator where it warms up again and rises back to the poles,
creating convection currents.
4. Which surface heats up faster, land or water? Explain why.
Land heats and cools faster than water. Land absorbs more of the Sun’s radiation while water reflects some of
the Sun’s radiation. Water also has a greater heat capacity, meaning that water is able to absorb a high amount
of heat before increasing in temperature.
5. Explain why a city on the coast would be warmer in the winter than a city that is further inland.
A city on the coast would be warmer in the winter because the ocean has been heated all summer and holds on
to heat, which warms the air throughout much of the winter. Water takes longer than land to heat up and cool
down.
6. In the spaces below, draw a picture and explain how the three types of heat transfer help move heat in our
atmosphere.

Explanation:
Explanation:
The sun’s rays are traveling
through empty space and are
heating the ground through
RADIATION.
The air molecules getting warm
by touching the ground directly,
so they are being heated by
CONDUCTION.
Once the air molecules are
warm, the air becomes less
dense and rises, while cool air
sinks. This is CONVECTION.
7. The following chart should help you explain high and low pressure. Use the boxes below, to fill in the missing
information.
Air Temperature
Air Density
Air is…
So this creates…
Warmer Air
Molecules spread
out further, making it
less dense
Rising
Low Pressure
Cooler Air
Molecules are
packed tighter
together making it
denser
Sinking
High Pressure
