distribution of water to earth

Question 1

Importance of Water

Answer 1

Biological

allows living things to grow, reproduce, and carry out important processes.

Question 2

Importance of Water 2

Answer 2

Keeps earth warm:

traps heat in the atmospheres as water vapor-which is a greenhouse gas.

Question 3

Importance of Water 3

Answer 3

Stabilizes earth’s temperatures:
water vapor temperatures changes temperature slowly because it has a high specific heat which allows for gradual seasonal changes.

Question 4

Specific heat-

Answer 4

Specific heat- the amount of thermal energy needed to raise the temp of 1kg to 1°C.

Question 5

hydrosphere

Answer 5

hydrosphere is all the water on or below earth’s surface and in the atmosphere.

Question 6

? of Earth’s water is salt water found in the ocean, while the other ? is fresh water, with ? of that ? found in huge masses of ice near Earth’s poles.

Answer 6

97% of Earth’s water is salt water found in the ocean, while the other 3% is fresh water, with 68.7%of that 3% found in huge masses of ice near Earth’s poles.

Question 7

water can change into all states of matter (?,?,?,) within Earth’s temperature range.

Answer 7

water can change into all states of matter (solid, liquid, gas) within Earth’s temperature range.

Question 8

water changing state process

Answer 8

gas
evaporation sublimation
condensation deposition
liquid solid
freezing
melting

Question 9

Ocean (salt) Water

Answer 9

97% of all water on Earth.
Has large amounts of salt in it; undrinkable.
Temperatures vary depending upon its location near the equator.

Question 10

seawater

Answer 10

seawater – water from a sea or ocean that has a large average salinity. Ocean water contains about 35 g of salt per liter.

Question 11

salinity

Answer 11

salinity – measure of the mass of dissolved solids in a mass of water.

Question 12

density

Answer 12

density -how much space an object or substance takes up (volume) as it relates to the amount of matter in that object or substance (mass).

Question 13

oceans are all connected; however, scientists separate the ocean into five main oceans
they are?

Answer 13

pacific Atlantic Indian Southern Arctic

Question 14

fresh water on Earth comes from ?, some of which is ? immediately or ? into the ?. The remaining water is ?, or water that flows over the ?.

Answer 14

fresh water on Earth comes from precipitation, some of which is evaporated immediately or soaks into the soil. The remaining water is runoff, or water that flows over the ground surfaces.
