🗑
|
||||
| What happens to water that gains energy? | It evaporates
🗑
|
||||
| What happens to water vapor that loses energy? | It condenses and may freeze
🗑
|
||||
| What happens when cold water is on top of warm water? | The warm water will rise because it is less dense and the cold water will sink. This will cause the water to mix and be a even temperature.
🗑
|
||||
| Describe what happens when salt water is ontop of fresh water. | Salt water will sink because it is more dense.
🗑
|
||||
| Describe what happens when fresh water is ontop of salt water. | Fresh water is less dense so it stays on the surface or "floats".
🗑
|
||||
| What drives deep water currents? | Different densities
🗑
|
||||
| What drives surface currents? | Winds
🗑
|
||||
| What form of energy do we get from the sun? | Electromagnetic
🗑
|
||||
| What type of heat transfers take place from the sun to our atmosphere? | The suns energy heats the ground (radiation)
The air molecules touching the ground are heated (conduction)
The warm air molecules move up and around, heating the atmosphere (convection)
🗑
|
||||
| Wind | Horizontal movement of air from areas of high pressure to low pressure.
🗑
|
||||
| Is cold air or warm air denser? | Cold air
🗑
|
||||
| Does cold air or warm air have greater pressure | Cold air
🗑
|
||||
| Which way will the wind blow? Ocean= 22 degrees Land= 28 degrees | From the ocean to the land (sea breeze)
🗑
|
||||
| Tornadoe | a narrow, violently rotating column of air that extends from the base of a cloud to the ground
🗑
|
||||
| What are 5 likely tornado conditions? | sping or summer
late afternoon
after tunderstorm
in tornado alley
where cold dry and warm moist air meet
🗑
