Valley
Occurs when water erodes rock in death it by following a straight path continuously
Meander
Produced when sediment is eroded from one side of a river and deposited on the other
The Rock Cycle
- magma
- crystallization
- igneous rock
- weathering, erosion, deposition
- sediment
- compaction and celebration
- sedimentary rock
- heat and pressure
- metamorphic rock
- melting
- magma
Where is metamorphic rock in the rock cycle?
After heat and pressure
What is between metamorphic rock and sedimentary rock in the rock cycle
Erosion and deposition
What is represented by these rock layers:
- Limestone (sedimentary)
- Shale (sedimentary)
- Sandstone (sedimentary)
- Granite (igneous)
A warm, shallow sea
What is represented by these layers:
- Limestone (sedimentary)
- shale (sedimentary)
- sandstone (sedimentary)
- marble (metamorphic)
Exposed to high heat and pressure, the experienced deposition
Troposphere
- where hurricanes form
- where a mountaineer climbing a tall mountain could reach
During rain, soil is washed into a nearby river. What two parts of the water cycle result in the loss of soil?
- precipitation
- runoff
Snow falls from the atmosphere and accumulates on a glacier. What part of the water cycle is this?
- Precipitation
What is happening when a storm passes through on a hot, sunny day and leaves the weather clear and much cooler than before?
A cold front has moved through the area
If you want to hike on a clear day with no clouds, what should you look for in the weather report?
A day when a high pressure system rests over the area
