Make a model of weathering, erosion, and deposition using a stream.
𝗠𝗮𝘁𝗲𝗿𝗶𝗮𝗹 𝗟𝗶𝘀𝘁
★1 Bag of sand
★1 Pen or pencil
★1 Cup of small rocks
★1 Large bottle of water
★1 Baking tray or similar sized
container
𝗜𝗻𝘀𝘁𝗿𝘂𝗰𝘁𝗶𝗼𝗻𝘀
★ In one half of the tray make a landmass with the sand (must be
sloped downward).
★ Lightly drag a pen or pencil through the sand in an “S” shape to
create a riverbed.
★ Place stones along the riverbed.
★ Slowly pour water where the riverbed starts.

When weathering breaks down the Earth's surface it forms small pieces of dirt, sand, and
small rocks. All of this material can get moved through erosion - this happened in the
model when flowing water in the riverbed moved some of the material down the hill.Eventually, these pieces ended up somewhere else. The process of the material being
deposited at the bottom of the hill is called deposition.
