Water On Earth 2020 Part 1
Test Description: 2020-21 Water
Instructions: Answer all questions to get your test result.
1) (75-65) percent of Earth's surface is covered with water.
A
65
B
75
2) Ninety-seven percent of the world's water is (fresh-salt) water, and most of that salt water is found in Earth's oceans.
A
salt
B
fresh
3) Of the three percent of Earth's water that is fresh, less than (10-1)% is found as surface water.
A
1
B
10
4) About (69-89)% of the freshwater on Earth is frozen in polar ice caps and mountain glaciers.
A
89
B
69
5) About (20-30)% of Earth's freshwater is found in the spaces between particles of rock in the ground.
A
30
B
20
6) Every drop of water is made of (thousands-millions) of water molecules.
A
millions
B
thousands
7) When a molecule contains bonded atoms with an unequal attraction for the shared electrons,it is called a (polar-tripolar) molecule.
A
tripolar
B
polar
8) Water can be found on Earth in (three-four) states.
A
4
B
3
9) Water as a gas, known as water vapor, can be found in the atmosphere.You (can-cannot) see water vapor.
A
cannot
B
can
10) Water molecules are polar--the positive and negative charges in different parts of each molecule attract each other.This attraction produces (cohesion-adhesion), that is, water molecules stick together.
A
cohesion
B
adhesion
11) (Cohesion-Adhesion) allows water droplets to stick to other objects, like a spider web.
A
Adhesion
B
Cohesion
12) Water has a (high-low) specific heat, so it can absorb a lot of energy without becoming too warm.
A
low
B
high
13) Because of its high specific heat, (less-more) energy is required to boil water than is required by many other substances.
A
more
B
less
14) Much of Earth's freshwater is frozen in polar ice caps and glaciers, some is stored in the ground, and a (large-small) percentage exists as surface water in lakes, swamps, and rivers.
A
large
B
small
15) Water's high specific heat means that it can (absorb-release) a lot of energy as heat and only increase its temperature by a small amount
A
release
B
absorb
16) Water's role as the universal (solvent-solution) means that it easily dissolves many other substances.
A
solvent
B
solution
17) When water vapor condenses into liquid water, energy is (released-absorbed) to the surroundings.
A
absorbed
B
released
18) (Sublimation-Deposition) happens when a solid changes directly into a gas without first becoming liquid.
A
Sublimation
B
Deposition
19) The (water-nitrogen) cycle carries water and any matter in the water around Earth.
A
water
B
nitrogen
20) Most of the water in the atmosphere comes from evaporation and (sublimation-transpiration).
A
transpiration
B
evaporation
