|---|---|---|---|---|---|
| Weathering is the process that? | Causes rock to change, breakdown and crumble through either a natural physical or chemical process.
🗑
|
||||
| Erosion is the process that? | Transports soil and sediment from one location to another by a natural physical process using wind, water, ice or gravity.
🗑
|
||||
| Loose, weathered material on Earth's surface in which plants can grow is? | Soil
🗑
|
||||
| The solid layer of rock beneath the soil? | Bedrock
🗑
|
||||
| Another name for mechanical weathering is? | Physical Weathering
🗑
|
||||
| Weathering orccurs most quickly in what kind of environment? One that is both... | Wet and Hot
🗑
|
||||
| The two most important factors that determine the rate at which weathering occurs are? | 1. The type of rock 2. The climate
🗑
|
||||
| The growth of plant roots and animal activity may result in this type of weathering? | Mechanical
🗑
|
||||
| Material moved by erosion is called? | Sediment
🗑
|
||||
| Karst Topography in which caves, valleys, and sinkholes are common is created by? | Ground water erosion where ground water sinks down into weathered limestone .
🗑
|
||||
| The force that moves rock and other materials downhill is called? | Gravity
🗑
|
||||
| Extra water that moves over the Earth's surface is? | Runoff
🗑
|
||||
| The wearing away of rocks by a grinding action is called? | Abrasion
🗑
|
||||
| A deposit in caves that hangs from the roof like an icecicle? | Stalactite
🗑
|
||||
| A deposit created by slow drippings in a cave that build up from the floor of a cave into a cone-shape formation. | Stalagmite
🗑
|
||||
| What are four types of mass movements? | 1. Landslides 2. Mudslides 3. Slump 4. Creep
🗑
|
||||
| This occurs when rock and soil slide rapidly down a steep slope. | Landslide
🗑
|
||||
| Which type of mass movement tends to be most destructive? | A Landslide
🗑
|
||||
| This often occurs after a heavy rain in a normally dry area. | Mudflow
🗑
|
||||
| What is a Mudflow? | Rapid downhill movement of a mixture of water, rock and soil.
🗑
|
||||
| What is a slump? | Occurs when a mass of rock and soil breaks away and slips down a slope in one solid mass.
🗑
|
||||
| What causes a slump? | Often occurs when water soaks soil rick in clay at the bottom of the mass causing it to weather and break down.
🗑
|
||||
| What is creep? | Slow downward movement of rock and soil.
🗑
|
||||
| What causes creep to occur? | Often results from the freezing and thawing of water in cracked layers of rock beneath the soil.
🗑
|
||||
| What are two types of Glaciers? | Continental and Valley
🗑
|
||||
| Energy from waves comes from this.. | Wind that blows across the waters surface.
🗑
|
||||
| Glaciers can only form in areas where... | More snow falls than melts.
🗑
|
||||
| The two processes by which glaciers erode the land are? | Plucking and Abrasion
🗑
|
||||
| The two processes by which waves erode the land are | Breaking down rock and tranporting sand.
🗑
|
||||
| Define plucking? | Process where a glacier flows over land picking up rocks in its path.
🗑
|
||||
| A mixture of sediments that a glacier deposits directly on the surface is called? | Till
🗑
|
||||
| A deposit of wind-blown sand is called? | Sand Dune
🗑
|
||||
| Wind causes erosion by? | Deflation and Abrasion
🗑
|
||||
| Define Deflation | The process by which wind removes surface material by blowing over the land picking up small particles of sediment.
🗑
