2022 All ANSWERED
Amphoteric - Correct Answer a substance that can act as both an acid and a base
Cohesion - Correct Answer water sticks to itself.
gives water surface tension and it has the highest cohesion of all nonmetallic liquids.
Adhesion - Correct Answer water sticks to other things.
specific heat - Correct Answer the heat required to raise the temperature of the unit
mass of a given substance by a given amount (usually one degree).
At what temperature is water most dense? - Correct Answer 4 degrees Celsius
The shape of the water molecule is unique with two hydrogen ions bonded to the side of
the oxygen ion. This give water several unique properties. Select four of them. - Correct
Answer Adhesion, cohesion, polarity, and high specific heat.
This unique property of water keeps the oceans from freezing from the bottom up. -
Correct Answer Water is most dense 4 degrees above its freezing point.
Water is most dense at about 4 degrees above freezing which means that liquid water
sinks. If it behaved like most other substances, it would increase in density until it froze
meaning lakes and the ocean would freeze from the bottom up and we and life would
not be possible as we know it.
What is an important result of the molecular process by which water freezes in contrast
with most other substances? - Correct Answer Ice floats on water.
Most materials become more dense when they freeze. Water molecules arrange
themselves in crystalline water with greater spacing than in liquid water meaning ice is
less dense than water and it floats.
water cycle - Correct Answer the cycle of processes by which water circulates between
the earth's oceans, atmosphere, and land, involving precipitation as rain and snow,
drainage in streams and rivers, and return to the atmosphere by evaporation and
transpiration.
Transpiration - Correct Answer When plants contribute significant amounts of water
vapor as a byproduct of photosynthesis.
Evapotranspiration - Correct Answer The combined amount of evaporation and
transpiration
, condensation nuclei - Correct Answer Microscopic particles on which water vapor
condenses to form cloud droplets.
Sometimes in the form of microscopic dust or salt.
Precipitation can take the form of what? - Correct Answer Rain, snow, hail, or sleet.
Surface Water - Correct Answer Precipitation that does not infiltrate the ground or
return to the atmosphere by evaporation or transpiration.
(Water in streams and lakes)
ground water - Correct Answer water that infiltrates into the soil and finally fill the pore
spaces in the rock or sediment deep underground.
(all subsurface water)
Precipitation - Correct Answer rain, snow, sleet, or hail that falls to the ground.
Interception - Correct Answer Water being prevented from reaching the surface by
trees or grass
Percolation - Correct Answer The downward movement of water through soil and rock
due to gravity.
Aquifer - Correct Answer An underground formation that contains groundwater
Runoff - Correct Answer Part of the water cycle where an excess of water runs down
and does not sink into the soil and eventually makes it to the rivers, lakes, and oceans.
Based on the water cycle, all water available to land dwelling organisms including
humankind, ultimately comes from where? - Correct Answer From the sky as
precipitation.
All water on land ultimately comes from the sky in the form of precipitation. We may
pump a lot of it from the ground, but in an ultimate sense, even ground water is
replenished from the sky. Thus increasing drought, predicted as a consequence of
global warming, is a serious concern!
What happens to water after falling to Earth as precipitation? SELECT ALL THAT
APPLY - Correct Answer It runs off
It evaporates
It infiltrates
What drives the water cycle? - Correct Answer sun
