land forms
These 3 things are formed by erosion
What is Canyons, riverbeds, and valleys
These are formed by deposition
Alluvial fans and Deltas
NEW earth material is created by this weathering.
What is Chemical Weathering
Soil must have this ingredient.
What is HUMUS
A Delta in a stream table ( is/ is not) larger when it has no slope (pencil slope)
What is NOT
Earth materials settle (slower/faster) if slope is STEEP
What is SLOWER
This is the definition of weathering
rocks broken into smaller parts
This is a term used to describe when pieces of rock are BLOWN AWAY BY WIND, and WATER CARRIES PIECES OF ROCK AWAY from a canyon
What is erosion?
Volcanic eruptions add new land by doing this.
What is adding rock to earth's surface
This causes particles in the earth to settle SOONER
What is large size? (Mrs Scoggins settles sooner that Annabeth in the chair)
This is how quickly landforms change due to Volcanic eruptions, landslides, earthquakes, and flash floods
What is RAPIDLY
This is how soil is formed. (2 things)
What is
-from weathered rock and humus
-rock breaks by weathering
WATER travels this speed if slope is STEEP
What is FASTER?
If a riverbed pours into the ocean and deposition is spread wide, it most likely will make this land form.
What is a DELTA
This is how quickly landforms change due to tree roots, chemical weathering, and freezing water.
What is SLOW?
This is what makes soil different from one place to another. (3 things)
-rock source
-amount of weathering
-humus is different because different plants and animals lived there.
This is how a stream table can help me understand a flood.
-clay and sand mix models the soil
- you can change variables ( ex: slope, amount of water coming)
-result=more deposition at the bottom spead out wider
larger slope= faster water
=deposition will stretch over longer distance
This is a description of deposition
What is pieces of rocks carried by WATER and SETTLE in a NEW location
Why did the gardener bury all her money?
to make the soil rich
What did one volcano say to the other
I lava you!
