Science : Water In The Ocean

Front 1

What affects the saltiness of the ocean's water?

Back 1

- Oceans are less salty where a river empties fresh water into the ocean. (dilutes)
- Ocean water becomes saltier the further away from the shore it becomes. (location)
- The warmer the water, the saltier the water. The cooler the water the less salty the water.(temperature)

Front 2

What is in ocean water?

Back 2

Ocean water is a mixture of water and dissolved solids.

Most of the dissolved solids are salts.

Front 3

Jon's water cycle description:

Back 3

The water cycle starts when water from lakes or oceans or anywhere is heated and evaporates. It rises into the atmosphere and condenses into bits of ice. The tiny bits of ice get heavier and heavier, so they fall as precipitation on Earth. Evaporation starts the water cycle again.

precipitation

Back 4

- Precipitation is formed when water vapor combines and becomes larger droplets. When they become heavy they fall to Earth as precipitation.
- Precipitation is rain, sleet, snow, or hail.
- Precipitation collects in lakes, rivers, oceans, and other bodies of water.

Front 5

What is the basic process of the water cycle?

Back 5

During the cycle, water changes from a liquid to a gas and back to a liquid.

Front 6

What is the most common salt in sea water?

Back 6

The most common salt in sea water is sodium chloride.

Front 7

transpiration

Back 7

Transpiration is the evaporation of water through plants.

Front 8

condensation

Back 8

Condensation is the process by which water vapor (gas)changes to a liquid.

Condensation happens when water vapor rises, cools, and changes from a gas to liquid water.

Front 9

How much of the world is covered by water?

Back 9

About 3/4 of the earth's surface is covered by water.

Front 10

evaporation

Back 10

Evaporation is the process by which liquid changes to gas.

Front 11

A gas changes to liquid by a process called______________.

Back 11

A gas changes to liquid by a process called condensation.

Front 12

Describe the water cycle.

Back 12

The water cycle is the constant recycling of water in the Earth's atmoshere.
- Heat from the sun causes fresh water to evaporate(evaporation)from the oceans.
- This evaporated water condenses (condensation)to form clouds.
- Fresh water falls from the clouds to the Earth's surface as rain (precipitation).
