Fri- Quiz on Water (vocab and notes)

2. Weather – condition of the atmosphere at a particular time and place.
Atmosphere – mixture of the gases that surrounds the Earth.
Altitude – height of an object above the Earth.
Troposphere – layer with 90% of the atmosphere’s total mass; layer where we live; (gets colder as you go higher)
Stratosphere – layer with the ozone layer; (gets warmer as you go higher)
Mesosphere – coldest layer of the atmosphere; (gets colder as you go higher)
Thermosphere – greatest heat, but not hot due to distance between air particles

3. ( gets warmer as you go higher)
8. Conduction – transfer of thermal energy by direct contact.
9. Greenhouse effect – Earth is getting warmer due to pollution and loss of ozone
10. Wind – moving air
11. Coriolis effect – Earth’s rotation causes objects (wind) to follow a curved path
12. Trade wind – winds that blow from 30 degrees lattitude to the equator
13. Westerlies – winds that blow from 30 to 60 degrees lattitude
14. Polar easterlies – winds that extend from 60 degrees lattitude

4. Water on Earth There are two types of water:
Fresh water & Salt water
Fresh water is water that is not salty
Most rivers and lakes are fresh water
Salt water is water that contains dissolved salts and other minerals
Water in the ocean is salt water
Humans and most land animals can not survive by drinking salt water

5. Earth’s Water Most of water on Earth is in the ocean
97% is salt water
Only 3% is fresh water

6. Water Cycle

7. Water Flows and Collects
Water collects in rivers and streams
River Systems
Tributary- a stream that flows into a lake or into a larger stream

8. Water Flows and Collects
River systems are divided into watersheds
Watershed (drainage basin)
Land that is drained by a water system
largest watershed is the Mississippi River watershed

9. Stages of a River Youthful Rivers Mature Rivers Old Rivers
Rejuvenated Rivers

10. Stream & River Deposits
Deposition is the process where material is dropped or laid down
Rock and soil deposited by streams are called sediment

11. Delta River deposits its load in a fan-shaped pattern
A river empties into a large body of water
Exp: Mississippi River flows into the Gulf of Mexico

12. Deposition on Land Alluvial fans Floodplains
Fan-shaped deposits that form on dry land
Floodplains
Area along a river that forms from sediments deposited when a river overflows
Rich farming areas

13. Prevent Flooding Dam Levee Barrier to redirect the flow of water
Buildup to control flooding

14. Conserve Water Only 3% of Earth’s water is drinkable
Most of the fresh water is frozen in icecaps and glaciers
How do we misuse our water?
How can we conserve water?

15. Pollution 2 types of Pollution: Point-Source Pollution
Pollution that comes from a specific site
Can mostly be controlled
Exp: a leak from a sewer pipe
Nonpoint-source Pollution
Pollution that comes from many sources
Difficult to control
Exp: street gutters, fertilizers and soil

16. Water has to be treated…

17. Earth’s Ocean What is the largest ocean? Pacific Ocean
What is the smallest ocean? Artic Ocean
Ocean water is salty.
Ocean water is not safe to drink.

35. Short Answers to Review Questions
Coastal water in hotter, drier climate typically has higher salinity because less freshwater runs into the ocean in drier areas. Heat increases the evaporation rate.
