Scientific Question of the Day

Which of the following is a benefit of recycling?

• A- reducing waste• B- increasing energy usage• C- decreasing use of post-

consumer material• D- increasing destruction of

resources

A is the correct answer

• Recycling reduces waste because materials are turned into or are used as something new, rather than being thrown away.

•What force pulls objects toward Earth?

•Gravity is the force that pulls objects toward Earth.

Land forms are always changing. Deposition is one process that changes land forms. What kind of force is deposition?• A- constructive• B- chemical• C- destructive• D- electrical

A is the correct answer

• Deposition is a constructive force.

The land forms we see today e the result of what kinds of forces?

• A- constructive forces only• B- destructive forces only• C- neither constructive nor

destructive• D- both constructive and

destructive

D is the correct answer

• Constructive forces and destructive forces together shape the land forms we see today.

Which of these causes rock to be slowly broken down into soil?• Landslide• Weathering• Earthquake• Fossilization

B is the correct answer

• Weathering is a process that slowly breaks down rock and turns it into soil.

• A- oil• B- inexhaustible resources• C- solar energy• D- fossil fuels

D is the correct answer

• Fossil fuels are all of the fuels that were formed over millions of years from the remains of plants and animals.

Which natural resource is formed from the remains of plants that died millions of years ago?

• A- water• B- lumber• C- coal• D- soil

• Humus is the decayed remains of plants and animals.

Beaches are often made of sand. The sand is carried to the beach by waves, which drop the sand on the shore. What is the name of this process?

• A- sediment• B- land form• C- deposition• D- abrasion

C is the correct answer

• Deposition is the process by which sand and sediments are laid down by waves.

Ocean waves pick up sand and soil from the shore. What is this process called?

• A- chemical weathering• B- erosion• C- deposition• D- sediment

B is the correct answer

• When ocean waves pick up materials, it is called erosion.

What type of energy causes the evaporation of water from lakes, oceans, and rivers?• A- mechanical energy• B- electrical energy• C- solar energy• D- potential energy

C is the correct answer

• Solar energy causes the evaporation of water from Earth’s surface. Evaporation from Earth’s surface is an important part of the water cycle.

Some farmers leave dead crop plants in the field over the winter. What does this prevent?

• A- rock formation• B- soil erosion• C- nitrogen fixation• D- soil formation

B is the correct answer

• A cover of dead plant materials helps prevent soil erosion.

Which of these is a renewable resource?

• A- oil• B- coal• C- wood• D- natural gas

C is the correct answer

• Wood is a resource that can be replaced in a relatively short period of time. It is a renewable resource.
