Weathering
The breaking down of rock on Earth's surface into smaller pieces.
weathering
The process by which weathered rock is picked up and moved to a new place.
Erosion
When sediments settle down on a location.
Deposition
Mountains and other surface features of the land.
Landforms
Large piles of sediment that are leftover from glaciers when they melt.
Moraines
Nonliving, solid material that are formed in nature and made of crystals.
minerals
When sediments carried away have different sizes, it is known as a ________ sediments.
poorly sorted
Fast/rapid flowing rivers can pick up small and large sediments that will then settle down. What type of depositional environment is being described?
High energy environment
A tall, protruding, spindly structure that forms within sedimentary rocks.
Hoodoos
A growing pile of deposited sediment at the mouth of a river.
delta
When rainwater seeps into cracks in rocks and __________, it expands and causes the rock to split apart.
freezes
This forces moves sediment in a landslide or a mudflow downwards.
gravity
What soil type is commonly deposited in low energy environment?
These are formed by the process of glaciation -- land will be covered by ice.
u shaped valleys
A gentle sloping mass of sediment that forms where a stream flows from a steep, narrow canyon unto a flat plain at the foot of the mountain.
alluvial fan
Bacteria and fungi in the soil that breaks down dead plants and animals.
decomposers
Name 4 agents of erosion.
wind, water, ice, gravity
The location where sediments are deposited.
depositional environment
Name a difference between weathering and erosion.
weathering makes things smaller, and erosion moves it
a long, narrow sandbank, especially at the mouth of a river
sandbar
These continuous cycles wear down and build up the Earth's surface

Give example of a depositional environment.
swamp, ocean floor, beds
