Is it getting hotter?
What is radiation
Energy from the sun!
What are water molecules in the air called?
Water vapor
How is hail formed?
water droplets in clouds get pushed up by updrafts into the colder part of the cloud where it then freezes.
How do clouds form?
Air vapor rises until it reaches a temperature where it eventually cools down and forms water droplets that are light enough to stay in the sky.
What is the purpose of a weather balloon?
To gather data about the upper atmosphere
What surfaces DON'T absorb the sun's radiation well?
light and shiny surfaces
Which of the following molecule forms is the best at absorbing the sun's radiation
Gas, Liquid, Solid
Solid! There are less places for the molecules to go!
What's an updraft?
What causes water droplets to fall from clouds?
The droplets get too big and heavy, causing gravity to pull them down
What weather event am I
Clue 1: Warm air rises quickly.
Clue 2: The air cools and forms a towering Cumulonimbus cloud.
Clue 3: I have electricity
Thunderstorm!
Pick the right one:
Warm air Rises/Falls, while cool air Rises/Falls.
Rises, Falls
What do molecules do when they get hot?
They speed up, move/bump past each other quickly, and spread further apart
How are hurricanes formed?
Water evaporates rapidly over warm oceans, causing storm clouds to build up and turn into hurricanes.
Why are vertical clouds, like the Cumulonimbus cloud, special?
They reach into all three cloud atmosphere levels, providing the cloud with several different internal temperature
how do warm oceans make storms in the area worse?
They produce more water vapor which gets added to the atmosphere.
How is the air in the lower atmosphere (where we are) warmer than the air in the upper atmosphere (Where clouds are)?
Because surface molecules are better at absorbing radiation from the sun than air molecules. The heat collected by the surface then warms up the aera/air around it.
What do molecules do when they cool down?
The move slowly and closely together
How is wind formed?
When hot and cold air come together, creating a difference in AIR PRESSURE!
How do clouds impact temperatures at the surface?
Clouds act like the lid of a box, keeping everything (warm air) in OR clouds also block the sun's radiation from reaching the surface, allowing the area to produce less heat.
BLANK air pressure always wants to move to BLANK air pressure.
HIGH & LOW
HIGH air pressure always wants to move to LOW air pressure
How do air molecules that have been heated up rise?
The molecules space themselves far apart so the air is LESS DENSE, allowing it tot rise above cooler air
what are molecules creating when they produce heat from the sun's radiation?
Kinetic Energy!!!!
What do big pressure differences in air/the atmosphere create?
Strong winds
What kinds of clouds are responsible for hail?
Cumulonimbus cloud
What water process forms in clouds?
Condensation
