Landforms Unit 5 Review

What change to Earth’s surface is caused by the force of a moving glacier?

• Formation of circular lakes
• Creation of flat plains
• Development of desert landscapes
• Glacial erosion and the formation of landforms such as U-shaped valleys.

Sandstone arches form in some desert environments. What occurred to form this arch?

• lava cooling down

• the depositing of sediment

• wind eroded surrounding rock layers

• glacial movement

Fifth graders created a model to show how sand dunes form.  They began by pouring sand into a tray and flattening it.  What should they do next?

• Blow air over the sand to simulate wind.
• Sprinkle salt on the sand to harden it.
• Cover the sand with a plastic sheet.
• Pour water over the sand to create mud.

If the process shown in the picture continues for a million more years, what could the new landform be named?

• Canyon
• Glacier

• Delta
• Valley

What is the difference between weathering and erosion?

• Weathering breaks down materials; erosion transports them.
• Erosion only occurs in water, while weathering happens in air.
• Weathering and erosion are the same process.
• Weathering transports materials; erosion breaks them down.

Over time, the river in the picture can change the shape of the canyon.  Which of the following best describes how the shape of the canyon might change?

• The canyon will become shallower and narrower.
• The canyon will remain unchanged over time.
• The canyon will fill with sediment and become flat.
• The canyon will become deeper and wider.

Explain how the canyon will get deeper and wider.

What process are these models designed to show?

• Valley formation by water and U-shaped valley formation by glacier.

• Soil formation techniques by fast moving water and wind

• Sedimentation processes by slowing water and the formation of deltas

• Volcanic activity by temperature change and strong winds

Which of the following best describes how organisms survive in a healthy ecosystem?

• Non-living things, like water and sunlight, are not important for living organisms in an ecosystem.

• Plants get energy from the sun, animals eat plants or other animals, and insects only live in the soil.

• Animals can survive without plants, but plants cannot survive without animals.

• All organisms depend on both living (biotic) and non-living (abiotic) parts of their environment to meet their needs, like food, water, and shelter.

Which statement best compares and contrasts different types of matter based on their physical properties?

• Solubility is the only property that can be tested in both solids and liquids.

• Only metals have measurable properties like mass and volume, while liquids and gases do not.

• All solids sink in water, liquids float, and gases dissolve in water.

• Matter can be described by properties such as mass, magnetism, and whether it sinks or floats, and some materials can conduct or insulate thermal and electrical energy.
