Hydrologic Cycle
Which of the following statements regarding the atmosphere is NOT true?
Air can be completely free of moisture.
What is the term for water that moves across the surface of the land and enters streams and rivers?
runoff
Which of the following factors does NOT affect surface currents?
density
Every year, the Moon's average distance from Earth increases by about 3.8 centimeters. When the Moon comes to be a much greater distance from Earth, Earth's oceans will experience
less extreme tides than they do today.
Nicole plans an investigation to determine the Sun's role in the water cycle. She places a tomato plant in the sunshine and one in a darkened room. She puts a clear plastic bag around a leaf on both plants. She waters the plants daily with the same amount of water. After two days, she notices that there are water droplets on the inside of the plastic bag on the plant that is
in the sunshine. What part of the water cycle does her experiment show?
It shows how sunlight triggers transpiration in the plant.
Which of the following is most likely to lead to atmospheric precipitation?
Warm air that cools toward its dew point as it rises.
What is transpiration?
a process in which plants lose water through the stomata in the leaf
The main driving force of ocean surface currents is
winds.
How often do spring tides occur?
twice every lunar month
Corbitt takes a bottle of juice out of the refrigerator. He notices that water begins to form on the outside of the bottle. Which of the following explains why the water started to form?
Condensation forms on the bottle because the room is warmer than the bottle.
A decrease in the temperature of a body of air could be associated with which pair of changes?
rise and expansion
Which of the following influence relative humidity?
air and water vapor
Which of the following is another name for undercurrents?
counter currents
What tide consists of a single high tide and single low tide daily?
diurnal
All substances can absorb a finite amount of energy. When the water in an area of ocean has absorbed all the energy it can hold, what will most likely happen?
The extra energy will cause the water to begin evaporating.
Steven is learning about the Sun in science class. He thinks that the Sun is only important for plants. Is Steven correct?
No, the Sun is a major source of energy and affects the wind, water, and organisms up the food chain.
Which of the following would most likely happen on a day when there is a lot of moisture in the air?
Water droplets would collect on cool surfaces.
Surface currents are continual, long-term factors that influence the climate of the Earth. What causes the formation of surface currents?
global winds
The mean average tide occurs later each day by how many minutes?
50 minutes
How would the change in the amount of solar energy trapped in Earth's atmosphere most likely affect the water cycle?
Increased solar energy can increase evaporation of ocean water and melting of the glaciers.
Which statement describes the most likely effect on the water cycle if global temperatures continue to rise?
More water would evaporate into the atmosphere which could lead to extreme precipitation events.
Which of the following best describes the primary cause of wave formation?
wind
Ocean currents are produced by
differences in the temperature of the water at different depths.
The gravitational force of the Moon and the revolution of Earth have the greatest effect on what energy source?
tidal energy
Which of the following will increase due to stormwater runoff?
the amount of water pollution problems
