Humans cut down trees in a location. This 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, geosphere

• atmosphere, hydrosphere, geosphere

• biosphere, atmosphere, hydrosphere

• cryosphere, atmosphere, hydrosphere

An unusually cold winter is a problem for Florida's manatees. Colder air temperatures cause water temperatures 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 manatee illness?

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

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

• Changes in the geosphere cause changes 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 water 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
