How might acid rain harm the environment?

It lowers the pH of bodies of water on the ground.

It traps heat near Earth’s surface.

It causes coal to burn less efficiently.

It allows harmful radiation from the sun to reach Earth.

How would the introduction of an exotic species most likely affect an ecosystem?

It would compete with native species for resources.

It would pollute the water or land.

It would increase the available resources.

It would cause the size of the ecosystem to increase.

Most producers use sunlight to make food through photosynthesis. What are the products of photosynthesis?

plant stems, leaves, and root systems

Energy is transferred from the water into the air.

Energy is transferred from the air into the water.

Energy is transferred from the water into the ground.

Earth’s surface is mostly water. However, only a small amount of water on Earth is clean fresh water. Why is it important to maintain water quality?

to keep water from becoming a nonrenewable resource

to keep the polar ice caps from melting

Many of the hybrid cars that people drive today run by burning gasoline, just as regular cars do. However, for some of the time that a hybrid car runs, it also charges an electric battery. This battery can be used to power the car so that the hybrid uses less gasoline than a regular car does. How could a hybrid car help reduce air pollution?

It burns less gasoline than a regular car does and thus produces less harmful exhaust.

It stores the harmful exhaust that it creates and uses that to power the car

It uses alternative energy sources instead of gasoline, which produces harmful exhaust.

It drives faster than a regular car does and therefore spends less time producing harmful exhaust.

Without other changes to a population, which of the following will cause a population to increase in size?

The birth rate is greater than the death rate.

The birth rate equals the death rate.

The birth rate is less than the death rate.

The birth rate and the death rate both equal 0.

Which of the following best describes the movement of heat energy in the global ocean?

Heat energy in warm surface currents is transported to areas near Earth’s poles.

Heat energy is transported to the equator from the continents.

Heat energy in deep currents is transported to the ocean’s surface.

Heat energy is transported from areas of lower temperature to areas of higher temperature.

What is weather forecasting?

studying data to predict likely future weather conditions

studying data to learn more about past weather events

studying many sources of data to learn more about current weather conditions.

studying data received from satellite images to learn more about current weather conditions

The following image shows a region used to grow crops. How does the image show a method of conservation?

Arranging the steep land into levels slows erosion.

Plowing land into layers causes plants to grow taller.

Making the land steeper helps water flow more easily.

the sum of mechanical energy and potential energy

stored energy due to chemical composition

Why do plants that grow in the tundra have shallow root systems?

They cannot grow through the permafrost.

They have no soil in which to grow.

They are frequently soaked by heavy rains.

They are trampled each time animals migrate.

The turbine shown below is used to produce energy for human use. What type of energy conversion takes place in the turbine?

wind energy to produce electrical energy

solar energy to produce mechanical energy

thermal energy to produce chemical energy

energy from moving water to produce mechanical energy

Coal is a natural resource. Why is coal considered nonrenewable?

Coal is being used faster than it is being produced.

No new coal is being produced on Earth.

Coal is used to produce energy and not materials.

Trees can be classified as different kinds of resources. Which of these statements gives a reason for classifying a tree as an energy resource?

It can be burned to provide heat.

It can be used to build a home.

It requires energy to grow a tree

The law of conservation of energy describes how the amount of total energy can change in a closed system. Which of these statements correctly describes this law?

Energy can be converted from one form into another, but it cannot be created or destroyed

The amount of kinetic energy in a system is a constant value

An object can have potential energy or kinetic energy, but not both at the same time.

The amount of energy created when an object moves is equal to the energy destroyed when it stops moving.

Three children are lined up to run a 50-meter race. The children all weigh the same. They start running at the same speed, but child 1 runs fastest over the final 10 meters and crosses the finish line first. What is true about the kinetic energy of child 1 at the moment she crosses the finish line?

It is greater than that of the other two children.

It is less than that of the other two children

It is the same as that of the other two children.

Child 1 has no kinetic energy at the moment she crosses the finish line.

All organisms must obtain energy from their environment. Every organism needs this energy in order to grow and reproduce. How do producers obtain energy?

They capture energy from sunlight and manufacture their own food.

They obtain energy by eating plants, bacteria, and algae.

They extract chemical energy from decaying organic matter.

They extract energy from the chemicals in soil, air, and water.

Which of the following is an example of commensalism?

A bird finds an existing hole in a tree and builds a nest in it.

A bird is hunted, killed, and eaten by a cat

A bird eats berries, then spreads the seeds.

A bird finds a small shellfish on a beach, cracks its shell, and eats it.

What is one way that a temperate rain forest is different from a temperate deciduous forest?

A temperate rain forest has a long rainy season rather than moderate, year-round rainfall.

A temperate rain forest has large populations of grasses rather than tall trees.

A temperate rain forest is made up of palm trees rather than coniferous trees.

A temperate rain forest has trees that lose their leaves in winter rather than keeping them year-round.

Which example represents an abiotic factor in an aquatic ecosystem?

The pH of a lake is decreased by acid rain.

Water lilies float on top of a pond.

A population of bass is living in a lake.

Dragonflies feed on small insects near a pond.
