What conditions in an ancient environment would make it suitable to the formation of fossil fuels?

• Movement of surface water causing weathering of rock.

• Frequent volcanic eruptions and forest fires.

• Extremes in high and low temperatures during the day.

• Abundant plant life and rapid laying down of sediments.

    

 

The formation of fossil fuels is a process that takes millions of years and starts with energy from the Sun. The Sun contributes to the formation of fossil fuels by –

• heating up the Earth's core where fossil fuels form.

• generating winds, so humans use less fossil fuels.

• giving energy to the living things that become fossil fuels.

• giving off heat, similar to burning fossil fuels.

 

Oil formation starts when organisms in the ocean die and then –

• get eaten by larger organisms that receive their energy.

• are carried by currents all over the planet.

• decay completely so that their matter is recycled.

• settle to the bottom and are buried in sediments

Most sedimentary rock forms in the ocean. This is because oceans –

• emit much less pollution than most other habitats.

• receive the majority of the Sun’s energy.

• have fewer plants and animals than on land.

• are where most bits of broken rock get deposited

The features of two groups of natural resources are listed here. See attached

Fossil fuels are considered nonrenewable resources because of which feature?

•  

   

  Where they come from

• How they are produced

• How useful they are

• How long they take to form

 

Sand dunes are created when sand is moved and deposited by –

• strong, persistent winds.

• slow moving sheets of ice.

• frequent lava flows.

• powerful ocean currents.

Rivers create landforms as they move across the surface of the Earth. Rivers move as water flows from -

• high in the mountains, down to oceans and lakes.

• regions that have warmer temperatures to cooler ones.

• because they are pushed by strong winds.

• from east to west as the earth rotates.

A delta is made of sediments deposited at the mouth of a river.  The delta is formed when –

• moving water slows down.

• blowing winds cool the land.

• drifting clouds produce rain.

• crashing waves erode soil.

Freeport, Texas, is built on a growing delta at the mouth of the Brazos River.  The land on which Freeport is built continues to grow because the Brazos River –

• deposits new material on the delta.

• removes sediments from the delta.

• moves farther away from the delta.

• receives fresh water from the delta.

Which forces create landforms such as deltas, dunes, and canyons?

• Volcanic eruptions

• Earthquakes and landslides

• Planetary movements

• Moving wind and water
