Unit 5 formative assessment study guide
Terms in this set (22)
amount of freshwater on earth
amount of salt water on earth
Two factors that determine the density of of water
Temperature and salinity
Temp at bottom of the ocean
Temp at top of the ocean
How does light, temp, and salinity change as you get deeper in the ocean
- light= decreases
- temp= decreases
- salinity= increases
What energy drives SURFACE currents
What 3 factors affect the flow of surface currents
- corriolis affect
Why has trash accumulated in patches in the ocean
Because of the direction of the currents and when they are all leading to one place, and that causes the garbage to gather into one space
The process of upwelling
- wind blows across shore
- corriolis effect
- water moves away from shore with wind
- cold water replaces the warm water
How does upwelling help the health of oceans along the contental shelf
- more dissolved oxygen
- helps underwater plants grow
Smallest daily tidal range
Greatest daily tide range
What force cause ocean tides
Moons gravitational pull
Why does the moon have a greater impact than the sun?
It is closer
How often does a diurnal tide occur each day?
What 4 factors cause rising sea levels
- more land added
- higher temps
- Ice age
Why do we care about rising sea levels?
It could cause crowding inland and could take away beaches
The biggest cause of shoreline erosion is...
How can oceans warm and cool an area?
If the temperature is warm, the water will be cold because the water takes a long time to change the temperature and if the temp. Is cold, the water will be warm because it is not caught up with the weather.
How can two points with different longitude, but same latitude, have different climates
Because the more center in the earth you are, the hotter it is and the more north or south you are, the colder it is in that area.
