Humans cut down trees in a location. This is caused an increase in temperature and decrease in rainfall in that location. Which of these Earth systems interacted to produce this difference in climate.

• biosphere, cryosphere, and geosphere

• atmosphere, hydrosphere and geosphere

• biosphere, atmosphere, and hydrosphere

• cryosphere, atmosphere, and hydrosphere

An unusually cold winter is a problem for Florida's manatees. Colder air temperatures cause water temps to drop which leads to manatee illness and death. Manatees will take shelter in the warmer waters found near natural springs and power plants. Which of the following accurately describes this chain of events leading to the manatees illness?

• Changes in the atmosphere cause changes to the hydrosphere, which affects the biosphere.

• Changes in the hydrosphere cause changes to the biosphere, which affects the atmosphere

• Changes in the geosphere cause changes to the to the hydrosphere, which affects the atmosphere

• Changes in the atmosphere affect the cryosphere, which affects the hydrosphere.

The interaction between the cryosphere and hydrosphere can have an impact on Earth's oceans. Which of the following is an example of an interaction between the cryosphere and hydrosphere?

• evaporation of eater from oceans at the equator

• release of fresh water into ocean water as icebergs melt

• decomposition of organic matter at the bottom of oceans

• release of large amounts of salt from icebergs into the ocean.

All interactions between the atmosphere and geosphere involve

• soil and living things

• water and living things

• soil and living things

• gases or particles in air or water

Which is a major source of energy for most of Earth's weather patterns?

• earthquakes along fault zones

• radioactive decay within earths interior

• convection currents in Earth's mantle

• Radiation received from the sun

Where are the sun's rays the most direct

• near the poles

• near the equator

• at high altitudes

• far from the ocean

fast moving molecules are associated with

• hot air

• cold air

• moderate temps

• solids

cold air tends to

• be less dense and flow over warm air

• be lifted up by more warm dense air

• be more dense and sink

• mix easily with warm air

The less mass in a given volume of air, the

• more the air weighs

• greater air pressure

• more dense the air

• less dense the air

______________ air can hold more water vapor and therefore be more humid

• cool

• warm

• windy

• denser
