Question 2

Satellites float here, as do low density particles.

The uppermost layer, that blends with what is considered to be outer space,

Answer 2

Exosphere

Question 3

Can reach up to 2500°C but lacks enough air molecules to transfer heat.

located above the mesopause and reaches out to around 600 kilometers (372 miles). Not much is known about the thermosphere except that temperatures increase with altitude.

Answer 3

Thermosphere

Question 4

Where meteors that enter the Earth burn up, protecting us from the effects of impact.

Reaches as far as about 85 kilometers (53 miles) above Earth’s surface. Temperatures decrease in the mesosphere with altitude.

Answer 4

Mesosphere

Question 5

Has the ozone layer, which protects us from the Sun’s ultraviolet rays.

the next layer up from Earth’s surface. It reaches from the top of the troposphere, which is called the tropopause, to an altitude of approximately 50 kilometers (30 miles).

Answer 5

Stratosphere

Question 6

Where most clouds are, and weather occurs.

thickest at the equator, and much thinner at the North and South Poles. The majority of the mass of the entire atmosphere is contained in the troposphere—between approximately 75 and 80 percent.

Answer 6

Troposphere

5. Lakes
6. Oceans and Seas

Question 12

Water Cycle

Answer 12

Evaporation
Condensation
Precipitation

Question 13

one of the major processes in the cycle, is the transfer of water from the surface of the Earth to the atmosphere. water in the liquid state is transferred to the gaseous, or vapor, state.

Answer 13

Evaporation

Question 14

is the deposition of a liquid or a solid from its vapor, generally upon a surface that is cooler than the adjacent gas

Answer 14

Condensation

Question 15

is all liquid and solid water particles that fall from clouds and reach the ground. These particles include drizzle, rain, snow, snow pellets, ice crystals, and hail. (This article contains a brief treatment of precipitation.

Answer 15

Precipitation

Question 16

These are massive bodies of ice on the Earth’s polar regions. They store 3/4 of the Earth’s freshwater.

Answer 16

Glaciers

Question 17

These are bodies of freshwater in an inland basin that are still or slow-moving.

Answer 17

Rivers and Tributaries

Question 18

is the water found underground in the cracks and spaces in soil, sand, and rock. It is stored in and moves slowly through geologic formations of soil, sand, and rocks called aquifers.

Answer 18

Groundwater
