|
liquid
|
|

The glaciers found in Alaska are an example of water in what state?
|
solid
|
|
|
As heat from the sun causes water to evaporate and turn into water vapor it goes from a liquid state to what state?
|
gas
|
|
|
The process of evaporation to condensation to precipitation and the repetition of this process is the
|
water cycle
|
|
|
The process where water escapes from the surface of a liquid and goes into the air is
|
evaporation
|
|
|
Clouds are the result of what happening to water vapor?
|
condensation
|
|
|
Water that collects in the cracks and spaces found below the surface of the earth is referred to as
|
groundwater
|
|
|
Ground that has small openings for water to pass through is
|
permeable
|
|
|
What is a Biogeochemical Cycle?
|
Earth's way of recycling natural resources
|
|
|
Water is made of
|
hydrogen and oxygen
|
|
|
Does the Earth have less, more, or the same amoung of water than it had a million years ago?
|
the same
|
|
|
How many times has Earth's water probably been recycled?
|
millions of times
|
|
|
What are the three forms of water?
|
solid,liquid, gas
|
|
|
When the air is dry, does water evaporate more quickly or less quickly?
|
more quickly
|
|
|
Which property of water makes molecules stick together?
|
polarity
|
|
|
What process causes water to cool to form clouds?
|
Condensation causes clouds to form.
|
|
|
Precipitation occurs when
|
water droplets become too heavy and fall to the ground.
|
|
|
What allows living organisms to live a distance from bodies of water?
|
water cycle
|
|
|
Which process takes place at the pores of plants?
|
transpiration
|
|
|
The amount of water in the ground is
|
less than in the oceans, 25 times more than all lakes and rivers, and only a quarter of the amount frozen in glaciers.
|
|
|
Which characteristic determines whether ground water will sink into the ground or run off?
|
slope of the land, level of ground saturation, rate of precipitation
|
|
|
The zone of saturation
|
is where water circulates underground and feeds rivers and streams.
|
|
|
When does the water table rise?
|
when precipitation falls
|
|
|
What decreases the rate of runoff?
|
vegetation
|
|
|
Permeable ground means
|
ground that water can pass through
|
|
|
The temperature of ground water increases with increasing
|
depth
|
|
|
Heated water comes to the surface through natural openings in the ground called
|
hot springs
|
|
|

|
75 percent
