True or false? Weather is defined as the prevailing long-term atmospheric conditions in a particular region.

Which of the following statements about Hadley cells is true?

The moisture in cool air condenses into clouds and precipitates because cool air holds more moisture than warm air.
Warm air expands and rises from the surface of the atmosphere around the poles.
Warm air begins to cool as it starts to sink at about 30° North and South latitude.
As warm air rises, air at the top of the atmosphere is pushed poleward and cools.

As warm air rises, air at the top of the atmosphere is pushed poleward and cools.

30° North and South latitude.
North Pole.

Equator

Aquatic biomes can be distinguished by chemical characteristics such as dissolved oxygen content and salinity and by physical characteristics such as water flow.
Which five of the following statements about aquatic biomes are true?

A freshwater organism permanently attached to the substrate would be unlikely to survive and reproduce in an estuary.
All wetlands have soils that dry out periodically.
Estuaries are very productive and are used as breeding grounds by many species of fish.
Tropical coral reefs generally exist in relatively shallow areas of the ocean.
The lowest levels of dissolved oxygen in a stream are generally found in its turbulent headwaters.
Temperature drives water movement in some lakes.
Wetlands have slow water movement or no water movement and no turnover.

Temperature drives water movement in some lakes.

Wetlands have slow water movement or no water movement and no turnover.

the order of seasonal turnover

1. surface water warms to 4 C and sinks
2. water mixes, bringing oxygen to the bottom and nutrients to the surface
3. warm surface water is separated from cooler bottom water by thermocline
4. surface water cools to 4 C and sinks
5. water mixes, bringing oxygen to the bottom and nutrients to the surface
