The natural chemical or physical processes that breaks down rock on Earth's surface. weathering true erosion false deposition false jackhammering false Single The process by which water, ice, wind or gravity moves weathered rock and soil from one place to another. weathering false erosion true deposition false dump truck false Single This type of weathering occurs when rock is physically broken down into smaller pieces of rock. physical weathering true chemical weathering false erosion weathering false deposition false Single This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock. physical weathering false chemical weathering true erosion weathering false deposition false Single How might a weathered mountain appear different than an unweathered mountain? Weathered mountain would be taller. false Weathered mountain would be rounder and less jagged. true Weathered mountain would be more jagged and less rounded. false Weathered mountain would have no trees. false Single How is physical weathering different from chemical weathering? Chemical weathering happens over much shorter time frame than physical weathering. false Chemical weathering changes the chemical composition of rocks; physical weathering does not. true Chemical weathering occurs only in tropical climates; physical weathering occurs only in cool climates. false Chemical weathering occurs only in the mountains; physical weathering occurs only on flat land. false Single How does freezing water cause the weathering of rocks? The freezing water— keeps the rocks in place false makes the rocks last longer false expands cracks and breaks rocks true causes rocks to fall in landslides false Single All of the following are causes of physical weathering except... plant growth false wind false acid rain true running water false Single Exposure to rain and oxygen causes the metal minerals in rocks to rust and fall apart.  This is an example of: physical weathering false chemical weathering true erosion weathering false deposition false Single Lichens (small green plants) growing on a large boulder release enzymes and other acids that slowly break the rock apart. This is an example of: physical weathering false chemical weathering true erosion weathering false deposition false Single
