Energy travels to Earth from the sun as ______
Electromagnetic Waves
100
The measure of how hot or cold something is, is called?
Temperature
100
What is the cause of wind?
the uneven heating of the Earth's atmosphere
100
What type of cloud creates hail?
Cumulonimbus
100
what is the most common type of precipitation? When does it occur?
Rain. It occurs when too many water droplets collect in a cloud. When the cloud is over capacity precipitation falls.
200
Name the 3 types of radiation.
Visible Light, Infrared Radiation, and Ultraviolet Radiation
200
If an item has a lot of energy what would it's temperature be?
HOT
200
Name 2 differences between a local and global wind
local winds- blow over small areas, caused by uneven heating in a small area global winds- blow over large distances, caused by uneven heating on a global scale
200
Name two storm clouds
nimbostratus cumulonimbus
200
How is precipitation measured?
rain gauge, meter stick

As energy from the Sun travels to Earth it interacts with the atmosphere. What are 3 ways it can interact with the atmosphere on it's way to the Earth's surface?
Ultraviolet Radiation can be absorbed by the Ozone Energy can be absorbed by the gasses Energy can be reflected by clouds Energy can be reflected by gasses
300
What are the 3 types of Heat Transfer?
Convection Conduction Radiation
300
Name a calm area, in regards to wind and a wind belt
calm- doldrum, horse latitudes wind- polar easterlies, prevailing westerlies, trade winds

Why are some clouds made of ice crystals, while others are made of water particles?
If at the dew point it is above freezing water droplets form, if its below freezing ice crystals form.

What is the difference between hail and sleet?
Hail is ice pellets bigger than 5mm in diameter and sleet is ice pellets smaller than 5mm in diameter
400
What happens to energy after it reaches the Earth's surface?
some gets radiated back into the atmosphere some is reflected off the Earth's surface absorbed by the land and water some is absorbed by gasses to heat the atmosphere
400
The Earth's Surface is heated by______________ Just above the Earth's surface is heated by ______________ 3m + above the Earth's surface is heated by ____________
radiation radiation conduction convection
400
What happens to wind as it blows from the South Pole to the Equator? Why?
As wind blows from the South Pole to the Equator, it's path becomes curved to the LEFT. Since the Earth rotates beneath the atmosphere the wind's path appears curved over the Earth's surface. (it curves the opposite way when blowing from the North)
400
Name the clouds from lowest to highest (there are 6)
Fog, Stratus, Nimbostratus, Cumulus, Cumulonimbus, Cirrus
400
What do the following instruments measure? barometer, anemometer, thermometer, psychrometer
barometer-air pressure anemometer- wind speed thermometer- temperature psychrometer- relative humidity
500
Explain the Greenhouse Effect, name 2 Greenhouse Gasses and why the Greenhouse Effect is good.
Energy that is radiated or reflected back into the atmosphere gets absorbed by GHG such as Methane, Carbon Dioxide or Water Vapor to create a blanket of heat.This process is natural and helps make the temperature on Earth comfortable.

When Miss Houde was little she touched the frying pan while making pancakes. What happened to Miss Houde's fingers and why?
Miss Houde's fingers got burned because the pan was heated through conduction (and possibly radiation). When Miss Houde touched the pan, heat was transferred to her hand through conduction.

Explain the difference between a sea breeze and a land breeze.
Land breezes occur at night because the water cools down slower than the land. Since the land becomes cooler, the air above the land is cooler and has a higher pressure. This causes the air to push the lower pressured warm air out of the way--creating a land breeze that blows from the land to the sea. The opposite of this is true for sea breezes (day, blows from sea to land)

Explain in detail how a cloud is formed.
The sun heats the Earth's surface. The air above the Earth's surface becomes warmer than the air higher up. The warm air becomes less dense and begins to rise, bringing water vapor up with it. As the water vapor rises, it begins to cool. Eventually it reaches the DEW POINT. If there are tiny particles present at the dew point, the water vapor condenses onto the particles and changes to liquid water known as water droplets. (this process is known as condensation.) Millions of these droplets near each other create a cloud.

What is the difference between freezing rain and sleet?
Freezing rain falls as rain and freezes when it reaches the Earth's surface. Sleet starts falling as rain, then it passes through air that is below freezing and becomes ice.
