weather

What type of air pressure system are you experiencing if there are cloudy skies, thunderstorms, warm water vapor, and air rotating inward in a counterclockwise motion?

• low pressure system

• high pressure system

stream like movement of water far BELOW the surface of the water NOT controlled by wind; a decrease in temperature and an increase in salinity often determine this type of current

• Atlantic ocean

• Deep ocean current

• surface current

• pacific ocean

____ currents travel from the poles and go toward the equator

Choose TWO statements that best describe the movement of ocean SURFACE currents.

• Sunlight heats the Earth unevenly, forming winds that push currents.

• As water evaporates, the salt is left behind causing the water to become less dense and sink

• The Earth rotates on its axis causing the apparent curving motion of fluids, called the Coriolis Effect.

• Cooler water from the poles sinks and travels toward the equator along the ocean floor.

surface currents travel from the ____ and go toward the ____

• equator, poles

• poles, equator

• north pole, south pole

Which statement correctly describes the types of weather in high pressure and low pressure

• Both high and low pressure areas generally have clouds and precipitation.

• High pressure areas have clouds and precipitation, while low pressure areas generally have clear skies

• Both high and low pressure areas have clear skies

• High pressure areas generally have clear skies, while low pressure areas generally have clouds and precipitation
  

____ liquids/air contract and sink

Water enters Earth’s atmosphere through two processes: evaporation from bodies of water, and transpiration from plants when they draw water from the soil and release it through their leaves.  Scientists estimate that 40% of all the water in the atmosphere is from transpiration. How might the loss of many trees and other plants impact the water cycle?

• The loss of many plants would cause an increase in evaporation to make up for the loss of water vapor in the atmosphere

• The loss of many plants would leave more water in the soil and decrease the amount of water in the atmosphere.

• The hydrological cycle would not be affected by the loss of plants because the majority of water vapor comes from evaporation. 

• The hydrological cycle would be affected by the loss of plants leading to an increase in precipitation. 

____ liquids/air expands and rises
