What's with this Weather?
What is the difference between weathering and erosion?
Weathering breaks rocks into smaller pieces; erosion moves those pieces away.
formed when sediments collect in water and become compacted
sedimentary rock
A volcano
Contains all of the Earth's water
hydrosphere
Name and describe a type of mechanical (physical) weathering process.
Possible - root or ice wedging, abrasion, exfoliation
The laying down of pieces of Earth's surface is called...
Deposition
Volcanic eruptions produce...
igneous rock
a fault
Humans are a big part of it
biosphere
A plants roots grow inside a rock and break it apart. What type of weathering is occurring?
What are the 4 main agents of erosion?
Water, ice, gravity, and wind
Name the processes that occur to turn igneous rock into sedimentary.
First it must undergo weathering and erosion to form sediment, then the sediment must compact and cement
this landform is created when 2 pieces of continental crust collide
What 2 spheres interact during the process of frost wedging?
hydrosphere and geosphere
Name and describe a type of chemical weathering.
possible - oxidation, dissolution, lichen growth, salt weathering
What processes happens first: weathering, erosion or deposition?
Weathering
Igneous rock that forms when magma cools and hardens
convergent boundary
What 2 spheres are interacting when a groundhog digs into the ground to build its den?
biosphere and geosphere
sedimentary, such as limestone
How can erosion affect landscapes? Give an example.
various answers possible. moving streams can cut a valley into a mountain, wandering rivers can deposit new sediments creating land
How do geologists determine the classification (type) of rock?
the way they are formed, color, texture and composition are all considered
This type of landform would be found where 2 oceanic plates diverge.
mid-ocean ridge
Give an example of the atmosphere interacting with any other sphere.
various responses possible - gases in atmosphere can be used by plants and animals to function
