Unit 4 5 6 Review

Which statement is discussing weather ONLY?

• The temperature there is normally warmer than most places.

• It's hot outside.

• The area is wet year round.

• Texas is know for hot and humid summers.

Answer explanation

Weather is now, climate is based off of LONG term data, 30 years or more.

Which statement is discussing climate ONLY?

• It's raining.

• It's was really cold last week.

• The area is wet year round.

• Tomorrows high is 72.

Answer explanation

Year round means every year (over 30 years).

Coal was produced in the earth over millions of years. Which of the following is NOT a step in the production of coal?

• Animals died and were covered by sediment.

• Plants died and were covered by sediment.

• Heat, pressure, and time changed the peat to lignite.

• Time and pressure changes dead plant material to peat.

Answer explanation

Coal needs dead plants ONLY. Dead plants and animals from oceans are required for Oil and Natural Gas.

Over long periods of time, fossil fuels form deep underground. Which components are related to the formation of fossil fuels?

• Lava, sand, and decayed animals.

• Decayed plants, lava, and minerals.

• Decayed plants and animals and water from oceans.

• Decayed plants and animals and sedimentary rock.

Answer explanation

Lava and water from oceans are NOT required.

How does evaporation occur?

• Solar energy heats the water, changing water to water vapor.

• Solar energy lights up the sky, changing water to water vapor.

• Water vapor condenses in the sky and forms clouds.

• Water collects and runs down into streams and rivers.

Answer explanation

The sun heats the water turning the water to a gas.

Which of the following statements describe the first step in the formation of sedimentary rock?

• Overlying pressure from rocks and soil reduce the size or volume of sediments.

• Weathered material is moved by wind, water, or ice.

• Exposed rock and other surfaces are broken down by wind, water, ice, or other elements.

• Weathered and eroded material is deposited by water, wind, or ice.

Answer explanation

To make sedimentary rock you have to have sediments. Sediments are made when a rock is weathered by water, wind, or ice.

During an investigation, students stand facing directly towards a lightbulb in the center of the room. The teacher asks the students to turn around slowly so that the light shines directly on the back of their heads. What period of time in the day & night cycle does this investigation model?

• 6 hours

• 12 hours

• 24 hours

• 48 hours

Answer explanation

If one FULL rotation of Earth takes 24 hours, then half of a rotation will take 12 hours.

The diagram in the picture shows the process of sedimentary rock formation. Which processes best fit in the box marked with an X?

• Weathering and compaction.

• Erosion and cementation

• Weathering, erosion, and deposition.

• Melting, cooling, and deposition.

The picture shows a river delta. The river is flowing into the ocean. How do river deltas change over time?

• More and more sediments build up around the delta. The river develops more branches.

• Water erosion continues. The ocean wears away the land, and coastline recedes.

• Water erosion continues. Smaller river branches disappear, and the main branch becomes deeper.

• Fewer sediments are deposited into the river system. The river valley dries up, and vegetation dies out.

After studying some of Earth's landforms, a group of students created the list below. Which of the statements listed in the image is false?

• Statement 1

• Statement 2

• Statement 3

• Statement 4
