Q3 W7 Review

A tornado’s severity can be estimated using the Enhanced Fujita scale. The severity is calculated using wind speed and the extent of the destruction. Examine the image for damage and suggest which category is most appropriate for the tornado.

• EF1

• EF4

• EF3

• EF0

• EF2

• B) It is shaped like a long, slim handle.

• C) It has an elevation close to sea level.

• D) It has a long coastline.

• E) It is farther south than most states.

Builders in Florida must consider frequent hurricanes when they build structures. Which of these is most likely to protect against hurricane damage?

Longleaf pine ecosystems are located in warm, coastal areas where frequent lightning causes regular

forest fires. These locations are also desirable for home construction. A group of engineering students

want to address how to build homes in an area next to a longleaf pine ecosystem. They build four

models of houses made of different materials and record the time it takes for each prototype to burn as

well as other information in a table.Which material and reasoning will the group share as the best material for building affordable homes near longleaf pine ecosystems?

• A. Brick; it is the most visually appealing.

• B. Red oak; it has the highest flame spread rating.

• C. Cedar; it takes longer to burn than red oak.

• D. Fiber cement; it is affordable and does not burn.

When forest trees are cleared from the land, and trees are not replanted, which of the following will most likely occur?

• soil erosion

• sedimentation

• lightning fires

• increase in habitat

Automobile engines built today are designed to be gas efficient. Gas-efficient engines most likely affect a city by reducing _____ pollution.

• air
• noise

• water

• land

Which choice correctly pairs an argument about conserving natural resources with evidence to support the argument?

• A. Nonrenewable resources do not need to be conserved. The environment will improve if the resources are depleted quickly.

• B. Nonrenewable resources need to be conserved. Alternative fuel sources are widely available for current use.

• C. Renewable resources do not need to be conserved. Use of renewable resources does not produce pollution.

• D. Renewable resources need to be conserved. Overuse of some renewable resources could deplete them faster than they can be renewed.

A city is powered by a natural gas power plant. Residents have recently installed solar panels that reduce the consumption of natural gas-generated electricity by 40%. If this trend continues and more people use solar power, how will this change directly affect the environment?

• It will reduce soil erosion and increase deforestation.

• It will increase the amounts of chemicals in nearby water sources.

• It will increase the production of electricity using fossil fuels.

• It will reduce air pollution and decrease greenhouse gases.
