Unit 4 Study Guide: Water Cycle & Location of Water

Water Cycle & Location of Water

Which of the water features shown on the diagram would MOST LIKELY contain salt

water

Sea

What is the main difference between a lake and a pond?

A lake is larger in size than a pond.

This table shows sizes of Earth's oceans:

Ocean Square Kilometers % of Earth’s Water

Pacific 168,723,000 46.6%

Atlantic 85,133,000 23.5%

Indian 70,560,000 19.5%

Southern 21,960,000 6.1%

Arctic 15,558,000 1.4%

Based on this table and the makeup of Earth’s total water, which reasonable

conclusion can be made?

Earth’s largest source of salt water is the Pacific Ocean

Which part of the diagram represents the largest amount of water on Earth?

Oceans

The Ogallala Aquifer is shrinking in size. Which describes why this is happening?

Overuse for agriculture

Which is a shared characteristic of all the locations marked by stars on the map?

Saltwater sources

Correctly label the unlabeled water cycle model

A = Evaporation, B= condensation, C= precipitation, D = Infiltration,

E = Transpiration

The Great Salt Lake in Utah has a saline content that can be up to ten times greater

than the ocean. It is fed by 3 freshwater tributaries. What causes the Great Salt Lake

to have such a high concentration of salt?

Salt becomes concentrated as water evaporates.

Where did the salt in Earth’s oceans originally come from?

Elements from Earth’s crust dissolve in water and return to the

oceans.

Usable freshwater comes from many places on Earth. Match the source of water

with its description

Snow fields- Natural reservoirs for many western, mountainous states;

responsible for almost all of the streamflow in a river.

- Oceans- 96.5% of water on Earth; supplies about 90% of the evaporated

water that goes into the water cycle.

- Precipitation- The primary delivery of atmospheric water to the Earth.

- Aquifer- This is is an underground layer of waterbearing permeable rock

from which groundwater can be easily extracted using a well.

- Surface freshwater- Streams (of all sizes, from large rivers to small

creeks), ponds, lakes, reservoirs, canals, and freshwater wetlands.
