• wetlands
• ponds and lakes

Multiple Choice

Which of these is NOT a marine biome?

• open ocean
• deep ocean floor
• seashore
• wetlands

Multiple Choice

_________ is the amount of salt dissolved in water.

• Temperature

• Salinity

• Nutrients

• Pressure

Multiple Choice

Which biome is pictured below?

• ocean
• freshwater
• coral reef 
• wetland

Multiple Choice

Wetland dominated by small trees and woody shrubs

• benthic zone

• glade

• marsh

• swamp

Multiple Choice

As rivers flow from their headwaters in the mountains down to flatter areas they become

• more narrow, faster, warmer

• faster, more narrow, colder

• wider, warmer, slower

• wider, colder, faster

Multiple Choice

These man-made structures are placed in a river to hold back large quantities of water, usually creating a lake. They can be a threat to river ecosystems if not managed properly.

• dams

• satellites

• solar panels

• none of these

Multiple Choice

An ecosystem where water covers the soil or water is near the surface of the soil is called

• a desert

• an ocean

• an estuary

• a wetland

Multiple Choice

What is the single most important difference between the marine, freshwater, and estuary biomes?

• Salinity (dissolved salt)

• Sunlight

• Oxygen

• Amount of Water

Multiple Choice

What aquatic biome is characterized by flowing fresh water?

• Lakes/Ponds

• Mangroves Swamps

• Rivers/Streams

• Coral Reefs

The "drainage basin" to where water from tributaries, streams, and rivers flow.

​

​Watershed

Multiple Choice

All water in a watershed flows ----

• downstream

• upstream

Multiple Choice

What is a tributary?

• a small stream that flows into a larger stream

• all the lakes in an area

• a map of the hills and valleys in an area

• a measurement of the amount of salt in water

These are smaller streams that meet up with a main river.

​

Tributaries

Multiple Choice

All water eventually empties into ---

• an ocean

• a river

• the ground

• a lake

Multiple Choice

Water stored in cracks and pores below the Earth's surface is called ---

• groundwater

• runoff

• precipitation

• surface water

Multiple Choice

All bodies of fresh water, salt water, ice, and snow that are found above ground are known as ---

• groundwater

• surface water

• glaciers

• precipitation

Multiple Choice

What is a river basin?

• the water in a river

• land that water flows across or under on its way to a river

• land around smaller streams, lakes, or ponds

• the channel that a river flows in

Basins are separated by HIGH ELEVATION. Every watershed has a boundary known as the DRAINAGE DIVIDE - the outermost limit of the watershed.

Basin

All the rivers, streams, tributaries, and creeks within a watershed.

River System

​North Carolina is divided into three regions:
Mountains
Piedmont
Coastal

The Coastal Plain is often divided into the Inner Coastal Plain and the Tidewater.

​

North Carolina Regions

Notice the FALL LINE!

This is the watershed divide. On one side of the mountain range, the waters flow toward the Atlantic. On the other side of the mountain range, the water flows inland becoming part of the Mississippi River Watershed.

​

North Carolina Regions

Multiple Choice

The green area on the NC map is the __________ region.

• Piedmont

• Coastal Plains

• Mountain

​Rivers MEANDER, or wind back and forth. The area around a river is considered a floodplain and is typically nutrient rich because the water picks up nutrients on its journey.

FLOODPLAINS contain wetlands.

River System Features

Multiple Choice

Which diagram shows the correct water flow patterns of watersheds?

• ponds, lakes or oceans -> rivers -> creeks -> mountains and hills

• mountains and hills -> creeks ->rivers -> ponds, lakes or oceans

• rivers -> ponds, lakes or oceans -> creeks -> mountains and hills

• mountains and hills -> ponds, lakes or oceans -> creeks -> rivers

​RIVER MOUTH

Where the river meets the larger body of water.

​

​DELTA

Often formed at the mouth of a river where there is a widening and slowing of water flow.

​

​ESTUARY

In this diagram, the estuaries would most likely be found within the DELTA.

​

WETLANDS

In this diagram, the wetlands are the salt marshes. They have a mixture of salt and fresh water. The level of water fluctuates based on the tides of the larger body of water. In the case of North Carolina, that larger body of water would be the Atlantic Ocean.
