What is erosion?

What is deposition?

Explain the effects of weathering and how it relates to erosion and deposition.

Geologists study the layers of rocks/fossils. The bottom layer is oldest and the top is the youngest. The 'law of superposition' states that this is true.

# data[].attributes.body
The law of superposition is something scientist use to determine the age of rocks. It lets you know that each rock layer is older than the one on top of it and younger than the one below it.

# data[].attributes.body
They use superposition to see witch lower layer is older

# data[].attributes.body
Scientists use the Law of Superposition to determine which layer is older than the other. The law of superposition states that the bottom layer is the oldest and the top layer is the youngest. With this, scientists can tell the age of rocks.

Geologists study the ages of rocks and fossils.

By the layers of rocks that they study

# data[].attributes.body
They use the law of superposition to help them determine the age of rocks. The one on top is always going to be younger then the one below it the law of superposition states that.

They use the superstitions by looking at the layers built on the rock such as the sediment layers

# data[].attributes.body
The law of superposion states that the layers of rock above the lower layers are younger than the ones below it. Since the older ones are made first, then it is logical to say that the younger rocksare on  the top.

Geologists study the layers of rocks/fossils. The bottom layer is oldest and the top is the youngest. The 'law of superposition' states that

# data[].attributes.body
Geology isa basic law of geochronology,stating that in any undisturbed sequence of rocks deposited in layers, the youngest layer is on top and the oldest on bottom, each layer being younger than the one beneath it and older than the one above it. They study rocks and fossils.

# data[].attributes.body
The law of superposition states that the lower the layer the older, it makes that true because new will be newer

# data[].attributes.body
You can tell the age of them from the law of superpostionwhich states that lower the layer the older layer, so they know that if its farther down then it's the older rock or fossil.

# data[].attributes.body
They look at them by age and the appearance of the rock and you can see if it has aged and if it has them it is probably a old rock and if it is a lower layer it is older and if it is a higher layer it's younger

# data[].attributes.body
The law of superposition states that the lower the layer the older the layer, well it is obvious that if a layer has grown over another layer the nephew layer makes the last layer older

# data[].attributes.body
The top layer is newer than the bottom layer
