Get ready… Here comes your first question.

The shape of land can be changed by… • weathering and erosion • heat and pressure • cooling • sediment

The shape of land can be changed by weathering and erosion. Correct Next question

Back to question SORRY That answer is not correct. Please try again.

Which of the following statements is true? • All rocks weather at the same rate. • All rocks weather, but not at the same rate. • Some rocks weather, while others do not. • Rocks do not weather.

Correct • True: All rocks weather, but not at the same rate. • Some rocks are made of softer materials; • some rocks are harder. Next question

The breaking apart of rocks into smaller pieces is called … • erosion • deposition • weathering • transposition

The breaking apart of rocks into smaller pieces is called weathering.Wind, water, ice, and plant roots are all responsible for weathering rock materials. Correct Next question

Which of these is NOT a force that causes erosion? • air • ice • water • wind

Correct • Air is NOT a force that causes erosion. • (Wind, water, ice, and gravity are the forces of erosion.) Next question

The process which acts upon sediment to form sedimentary rocks is… • heat • cooling • pressure • all of these

Correct • The process which acts upon sediment to form sedimentary rocks is pressure. • Sedimentary rock is formed by layers of sediment pressing down on each other, cementing the layers together. Next question

The moving away of weathered pieces of rock is referred to as … • deposition • weathering • erosion • transportation

The moving away of weathered pieces of rock is referred to as erosion. Correct Next question

A glacier can be a destructive force because… • it scrapes away land • it forms lakes • it is a large river of frozen ice • it moves very slowly

A glacier can be a destructive force because it scrapes away land. • Correct Next question

Scientists use all of the following to learn about Earth’s past EXCEPT… • What materials are found in different layers of sediment • What kinds of rocks are in an area • Tree ring size • The moon phase cycles

Scientists use all of the following to learn about Earth’s past EXCEPTmoon phase cycles. • Correct Next question

Which of these could be considered a positive effect of erosion? • washing away trees from a farmer’s field • damming a river with fallen logs • forming a delta at a river’s mouth • topsoil being washed away

Correct • Forming a delta at a river’s mouth could be considered a positive effect of erosion. Next question

All of the following are true about the moon EXCEPT… • The moon is smaller than earth. • The moon has less gravity than earth. • Rocks weather and erode on the moon. • Mountains can be found on the moon.

Correct All are true about the moon EXCEPT rocks weather and erode on the moon. Rocks do not weather and erode because the moon does not have any forces of weathering or erosion – wind, ice, water, or plants. Next question

Wind is mostly caused by… • the uneven heating of the earth • precipitation • moving air • water heating up faster than land

Wind is mostly caused by the uneven heating of the earth’s surface. Correct Next question

Inexhaustible resources... • took millions of years to create. • come from the earth’s surface. • cannot be used up. • move in a cycle.

Inexhaustible resourcescannot be used up.Wind, sunlight, and ocean tides will be around forever without having to be replenished. Correct. Next question
