Answer each of the following questions to the best of your knowledge. You may not use notes or help each other during the test. You have both 8th and 9th periods to work on this.

Topics:

Streams and Drainage Patterns

2.

Sort processes into one of the 3 types of stream transport

  • ions in solution

  • sand grains that are picked up by the current when it is strong and settles out when it is weaker.

  • loose materials are removed from the bed and carried by the fluid

  • pebbles roll along the bottom of a river

  • coarse grains are pushed by the current

  • bed load

  • saltation

  • dissolved load

7.

Deep water masses form as a result of dense water sinking to the bottom of the ocean. The deepest water masses form in which of the following locations? 2 answers

8.

How old is the ocean? The Thermohaline Circulation pattern of the Earth's oceans allows all the water in the oceans to mix. Because it is driven solely by density, it moves rather slowly, at about 1 cm per second on average, and must travel ~31,500 km to make a complete loop. Using this information, how long does it take for the oceans to become completely mixed?

HINT: watch out for units that need to be converted!

9.

Below is shown a tidal chart for the Seattle Harbor. About how much does sea level rise due to tides in this region?

Asemmisa {{asɛmmisaAhyɛnsode}}
10.

Does temperature or salinity have a stronger effect on the density of water?

Thermohaline Circulation allows for the flow of , which in turn is controlled by . The strongest of these effects is

The East and West Antarctic ice sheets are separated by the TransAntarctic Mountains. Although they share a continent, they are wildly different in their stability. The map and graphs below show how ice thickness across the Antarctic continent is variable, with thin ice over the mountains and thick ice over East Antarctica.

Using this image and your knowledge of glaciers, explain at least 2 reasons why ice thickness plays a role in the stability of the ice sheets.

Glaciers carry a variety of sediments and grains in the ice due to erosion occurring as the glacier flows. Once the glacier melts away, which of the following is the type of sediment that forms from the varied grains collected by the glacier through its journey?
