This is a harmful substance in air, water, and/or soil. Ex: smog, oil spill, chemical spill
What is a pollutant.
100
This is the most common form of precipitation.
Rain
100
What are the 3 MAIN types of clouds?
cirrus, cumulus, stratus
100
What are the 3 MAIN parts of the water cycle?
What is evaporation, condensation, precipitation
100
Layers of the atmosphere are classified according to changes in what?
Temperature
200
What percentage of the atmosphere is made up of trace gases?
What is 1%
200
What is freezing rain?
Rain that freezes when it touches a cold surface.
200
What are the 2 types of clouds that drop significant amounts of precipitation?
cumulonimbus and nimbostratus clouds **nimbus=rain**
200
What is precipitation?
Any form of water that falls from clouds and reaches Earth's surface.
200
List the 4 MAIN layers of the atmosphere, in order, from GROUND to OUTER SPACE.
Troposphere, Stratosphere, Mesosphere, Thermosphere
300
What is smog?
Combination of smoke and fog.
300
Sleet is ice particles that are smaller than ______ in diameter.
5 mm
300
What is a cumulonimbus cloud? Describe it and tell me what level cloud it is.
-A dark cloud with a flat base that forms about 1,000 ft above the ground and grows up to over 39,000 ft in height. It brings thunderstorms and a lot of rain in a short period of time. -vertically developing cloud
300
What is condensation?
The changing of water vapor (gas) to liquid water or ice. It occurs when warm air rises and cools, causing the gas form to change back to liquid/solid.
300
This is the layer that we live in and where all weather occurs.
Troposhere
400
What are the 3 gases that make up Earth's atmosphere and what are their percents?
Nitrogen-78% Oxygen-21% Trace/other gases-1%
400
How does snow form?
Water vapor inside the cloud is converted/changed directly into ice crystals (gas to solid)
400
What is a cirrus cloud? Describe it and tell me what level cloud it is.
-A wispy, thin cloud, made of ice crystals, does NOT produce weather/precipitation, seen on nice days. -high level cloud
400
What is evaporation?
Heat changes liquid water to water vapor (gas) and it rises up into the atmosphere.
400
This layer contains the ozone layer in the upper part and jets fly in the lower portion.
Stratosphere
500
Why is the atmosphere important?
-allows life to exist -prevents meteoroids from entering/hitting Earth's surface -keeps us warm!
500
How does hail form and in what type of cloud does it form?
It forms in cumulonimbus clouds and forms when ice pellets are carried into cold regions of the cloud by updrafts, adding a layer of ice each time.
500
What are the 2 ways clouds are classified?
Shape and altitude
500
If we always have the same amount of water on Earth, then why do droughts occur? Where did all of the water go?
Water can be stuck in various places and be inaccessible. It may be frozen in glaciers or stuck in the clouds.
500
What is the scientific name for the Northern Lights and which layer do they form in?
Aurora Borealis, ionosphere (bottom part of the thermosphere)
