Hydrosphere Review Quiz

Since aquifers are underground, the water can not evaporate into the atmosphere.

Keeping the water running while washing dishes is not a good way to conserve water. This practice leads to unnecessary water wastage as the water continues to flow even when it is not needed. To conserve water, it is recommended to turn off the tap while washing dishes and only turn it on when necessary.

The Sonar device sends a signal to the ocean floor and a scientists waits and times how long the signal takes to return to the ship. The longer it takes to come back, the deeper the ocean floor is.

Since an estuary is made up of freshwater and salt water is mixed into it, the water would not be considered fresh.

Aquifers are the rock layers the surround the groundwater. As the water seeps through the aquifer, it is purified.

Remember that the difference between river basin and watershed is that watersheds are smaller and they make up river basins. Estuaries are where the river meets the ocean. Aquifers are the rock layers that surround the groundwater.

Photosynthesis adds to the dissolved oxygen

An estuary is fed by the river and swamps and it leads to marshes.

Since they can survive there, we call them tolerant, because they can tolerate the pollution. Tolerate means they can "put up with" the pollution without it killing them.

Cool water is denser than warm water. Cool, dense water tends to sink toward the ocean floor. As surface water sinks, it is replaced by deep water. Deep water moves up towards the surface bringing nutrients with it.

Eutrophication is the overgrowth of plant life which is what happens when there is too much nutrients in the water

Since there is only going to be 1 sewage plant in a city, it can only be coming from one place. Anytime you see runoff, you know it is NPS. You can not trace the acid rain back.

Cohesion is water sticking to other water molecules. Since water "sticks" to water, at the surface the water molecules will come so close together that this will allow the insect to walk on water.

The neritic zone is the zone that follows the intertidal zone.

Distillation is the process of boiling water to separate the salt from the water and then collecting the water and cooling the water back into liquid water. Reverse osmosis uses filters to separate contaminants from water.

The hotter the water, the less DO you have. The cooler the water, the more DO you have.

Planting vegeation around waterways actually help them, not hurt them.

Generally, faster moving water has a higher level of oxygen that slower-moving water. This is because the swift currents flow over rocks and other land surfaces making them better able to dissolve atmospheric oxygen.

Anoxic means very little oxygen

GIS is like GPS but has more features. It explains the location, conditions, trends and pattern of features on earth.
