Fresh and Saltwater Systems

Glaciers are moving masses of snow and ice. A glacier that forms over an extensive area of relatively level land and flows outwards in all directions from its source is called a ...

Glaciers affect the water cycle in many direct and indirect ways. Their DIRECT influence is...

• they speed up evaporation as they melt

• decrease the amount of accumulation

• slow down the speed at which water travels through the cycle

• prevent groundwater from evaporating

If the temperature of a glacier increases and there is more melting than accumulation then...

Which of the following is NOT an important reason for monitoring sediment?

• Increased sediment could block a city's water intake pipes

• Sediments carry toxins which could affect organisms living nearby

• Increases sediment means more land is eroding upstream

• Increased sedimentation could indicate an increased chance of flooding

Similar to plants and other photoautotrophs which live in the upper reaches of the ocean and conduct PHOTOSYNTHESIS to produce their own fuel using energy from the sun, there are certain microorganisms which can support entire food chains at the bottom of the ocean using the energy from chemicals spewing out of underwater vents. This process is called...

• photosynthesis

• chemosynthesis

• hydrosynthesis

• thermosynthesis

The mangrove tree has adapted two specific processes to help it survive where it lives. Mangrove roots are able to block the uptake of excessive salt when it is absorbing the water it needs to survive. The mangrove is also has special salt excreting glands on its leaves to get rid of the salt that enters the tree at lower concentrations. What type of ecosystem would you find a Mangrove tree growing in?

• Intertidal Zone

• Oceanic Zone

• Estuary

• River and Stream

Waves are created out in the open ocean by winds blowing over the surface of the water. As the wave grows in size the water particles...

• move towards the shore

• move out in the direction of the wind

• move up and down in one spot

• move around in a circular motion
