SC Benchmark 3 Review

The map below shows how much precipitation is predicted in the United States for a particular winter. Scientists use advanced computer technology to help construct such maps. Which of the following describes how this type of computer-generated map is most useful?

• It can be used to predict the low temperature for any given day in winter.

• It can help in changing the direction of cold fronts.

• It can be used to plan for water resource management.

• It can predict the exact amount of snowfall in a specific city.

What is one benefit of predicting weather accurately?

• It can stop natural disasters from happening.

• It can make it rain whenever needed.

• It can give people time to prepare for possible flooding.

• It can help change weather to better meet the needs of a given region.

What is an oxbow lake?

• A lake shaped like a C, formed when a river curve is cut off

• A lake found in the mountains

• A lake that is always circular

• A lake that forms in the ocean

What is the initial action to create a model of an oxbow lake?

• Carve a winding channel in the sand

• Increase the water flow to maximum

• Place stones along the path

• Draw a straight line in the sand

How can you simulate a gentle stream in the model river?

• Turn the water hose on low and let the water flow slowly

• Turn the water hose on high immediately

• Use a bucket to pour water

• Leave it empty

A conservation group wants to control some of the destructive processes created by erosion in a coastal area. Which of the following actions below describe the steps this group should take?

• Place a series of mesh panels along (perpendicular) the beach to catch the sand.

• Build underwater walls 100 miles from the shore line

• Introduce non-native plants and animals to the area

• Restore a lighthouse to warn ships of the rocky coast line
