Weathering is altering the color, texture, composition, or form of exposed objects. The breakdown of rocks on earths surface, by rainwater, extreme temperatures, and biological activity. The wind has weathered down the rocks to form that shape.

How many different types of weathering is there?

# data[].attributes.body
There is three types of weathering they are physical, chemical, and biological

# data[].attributes.body
geological process of rocks breaking apart without changing their chemical composition. Over time, movements of the Earth and environment can break apart rock formations, causing physical weathering. an example is the rock being split in half.

What is chemical weathering and what different types are there?

What is chemical weathering and what different types are there?

# data[].attributes.body
What happens when rocks are broken down and chemically altered. hydrolysis, oxidation, carbonation, acid rain and acids produced by lichens are the different types of chemical weathering. like the fungus growing  on this rock.

# data[].attributes.body
The weakening and subsequent disintegration of rock by plants, animals and microbes. Like this tree bringing up the road.

How is erosion different from weathering?

# data[].attributes.body
Erosion is the process by which soil and rock particles are worn away and moved elsewhere by wind, water or ice. Weathering involves no moving agent of transport.

Erosion is the process by which sediment and other materials are moved from one place to another. Like this picture showing how the water eroded this canyon.

Either from come come from the bed of the stream or the banks. It also could have traveled by rainwater runoff.

What factors determine if a stream can Erode materials?

What factors determine if a stream can Erode materials?

# data[].attributes.body
If a stream has gradient, discharge, and load they are the main factors that can control what sediments a stream carries.

# data[].attributes.body
Gradient is the measure of the change in elevation over a certain distance. Materials carried by a stream are whats called the stream's load. The amount of of water that a stream carries in a given amount of time is called discharge.

# data[].attributes.body
A stream can create a canyon and valley by erosion. the erosion of the grand canyon took millions of years it used to just be a flat surface. If the water travels through places long enough you can get a valley like below.

What landforms are made by groundwater erosion?

What landforms are made by groundwater erosion?

# data[].attributes.body
Groundwater is the water that is located within the rocks below earth's surface. The groundwater is slightly acidic so it can dissolve rock. When this happens it can form underground caves.

# data[].attributes.body
A shoreline is the place where land and a body of water meet. Strong ocean waves will erode materials rather than leave them. Currents form a zigzag movement in the sand and at the sand moves down the beach is eroded away while the down current end of the beach builds it up.

# data[].attributes.body
Deposition is the process by which eroded material is dropped. Like in this picture the waves are leaving behind pebbles and sand on the shore.

# data[].attributes.body
When gravity's downward pull on sediment is greater than the push of flowing water or wind. which usually happens when the water or wind slows down.

# data[].attributes.headline
Where does a stream deposit the materials?

# data[].attributes.subject
Where does a stream deposit the materials?

# data[].attributes.body
A stream can deposit materials along the bed, bank, and mouth, which will eventually form different landforms.

# data[].attributes.body
Deposition can create floodplains, deltas, and Alluvial fans. Many layers of deposited sediment can form a flat area which is a floodplain. A fan-shaped pattern that a stream deposits their loads in is a delta. a fan-shaped deposit that forms on dry land is an alluvial fan. On the upper right you can see the beginning of the delta and where the deposits (load) where dropped off.

# data[].attributes.body
Yes, because they create icicle-shaped deposits know as stalactites and stalagmites. when the groundwater level is lower than the level of the cave the roof of the cave  may not be able to support it which is what happens when a sinkhole is created. Like in the image below a sinkhole was created after the weight of the water couldn't be held.

# data[].attributes.body
Look at the definition in erosion. Gentle waves will bring in deposit materials and current can too.The waves that  strike areas between headlands have less energy which means they are more likely to deposit materials than erode them.
