- 1. Multiple ChoiceBobby observed that a metal trash can was covered with rust. What type of weathering caused the rust on the trash can?Mechanical weatheringWind weatheringChemical weatheringErosion weathering
- 2. Multiple Choice
Which diagram represents mechanical weathering?GFHJ - 3. Multiple ChoiceThe surfaces of old concrete statues are often covered with small holes or pits. Which of these MOST LIKELY causes these holes or pits?The concrete becomes pitted as water freezes in small cracks in the statue.The concrete is chipped away by sand particles blown by strong windsThe concrete is chemically weathered by acid rain.Long exposure to sunlight causes the pits to form.
- 4. Multiple ChoiceWhat is the weathering process in which rocks are broken down into smaller pieces (sediments) and do not change the rock composition?Acid weatheringGravity weatheringChemical weatheringMechanical weathering
- 5. Multiple ChoiceWhat is the process that picks up and moves weathered rocks?depositionlandslideweatheringerosion
- 6. Multiple ChoiceHow are canyons formed?Wind blows sand into high piles, which form the canyon walls.Rivers erode soil and rock over time, leaving behind canyon walls.Gravity causes rocks to fall from mountain sides onto valley floors.Ice freezes and thaws in cracks of rocks, and the cracks become canyons.
- 7. Multiple ChoiceA cliff formed near the ocean. Which statement best describes how this cliff formed?Warm air melted the rock.Sun rays evaporated the rock.Ocean waves washed away rock.Plant roots pushed away the rock.
- 8. Multiple ChoiceWeathering causes rocks and minerals to break into smaller pieces. Which event is the best example of weathering?a raindrop splashing in a lakea snowball rolling down a mountaina tree root growing into the crack of a rock
- 9. Multiple ChoiceOver long periods of time, deposition may change the Earth’s surface by _____.forming new land featuresbreaking down large rocks into smaller oneswashing away beachesseverely draining topsoil
- 10. Multiple ChoiceSarah does the investigation described below using a model to study how rivers erode earth materials.
· She pours 600 mL of sand onto a plate.
· She pours 150 mL of water onto the pile of sand.
· She measures how much of the sand washes off the edge of the plate.
· She notices that less sand washes off the plate when she pours water slowly than when she pours it faster.
How is the model similar to real rivers eroding earth materials?The model shows that faster-moving water makes sand stick to the bottom of a river.The model shows that slower-moving water makes sand float to the top of a river.The model shows that slower-moving water erodes less earth materials than faster-moving water.The model shows that faster-moving water erodes less earth materials than slower-moving water. - 11. Multiple ChoiceDeposition changes the Earth’s surface because eroded materials _____.stop the river's flowmake rich farmlandsare dropped in new placesmove very slowly
- 12. Multiple ChoiceWhat has the greatest erosion effect on our beaches?wavesgravityglacierswind
- 13. Multiple ChoiceThe natural chemical or physical processes that breaks down rock on Earth's surface.weatheringerosiondepositionjackhammering
- 14. Multiple ChoiceThe process by which water, ice, wind or gravity moves weathered rock and soil from one place to another.weatheringerosiondepositiondumptruck
- 15. Multiple ChoiceThese rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:ice wedgingacid rainpermeabilityabrasion
- 16. Multiple ChoiceThese gravestones have slowly broken down and turned a blackish color due to the action of:ice wedgingabrasionacid rainmechanical weathering
- 17. Multiple ChoiceHow is mechanical weathering different from chemical weathering?Chemical weathering happens over much shorter time frame than mechanical weathering.Chemical weathering changes the chemical composition of rocks; mechanical weathering does not.Chemical weathering occurs only in tropical climates; mechanical weathering occurs only in cool climates.Chemical weathering occurs only in the mountains; mechanical weathering occurs only on flat land.
- 18. Multiple ChoiceWeeds growing into the cracks in a sidewalk and the sidewalk begins to crumble is an example of:mechanical weatheringchemical weathering
- 19. Multiple ChoiceA metal statue slowly turning green after years of being outside is an example of:mechanical weatheringchemical weathering
- 20. Multiple ChoiceA piece of sandstone changing color (from brown to rusty red) from exposure to water and air is an example of:mechanical weatheringchemical weathering
- 21. Multiple ChoiceLichens (small green plants) growing on a large boulder release enzymes and other acids that slowly break the rock apart. This is an example of:mechanical weatheringchemical weathering

- 32. Multiple ChoiceMany landforms are created through the process of weathering and erosion. Which statement correctly compares weathering and erosion?Erosion can make weathering happen slower by breaking up rocks.Weathering can help erosion happen faster by breaking up rocks.Weathering and erosion must always take place at the same time.Weathering and erosion are two names for the same process.
- 33. Multiple ChoiceHow does freezing water cause the weathering of rocks? The freezing water—keeps the rocks in placemakes the rocks last longerexpands cracks and breaks rockscauses rocks to fall in landslides
- 34. Multiple ChoiceLayers of sediment forming at the bottom of the ocean floor is an example ofWeatheringErosionDepositionAwesome Science
- 35. Multiple ChoiceHow do plants weather rocks?During photosynthesisWhen roots grow into cracks of rocks and expand the rock breaks.When the plant moves water from the roots to the leaves, the rock breaks.Plants don't weather rocks.
