They look at other rocks and the one on the bottom is the oldest, and the top is the youngest

# data[].attributes.body
They use it tell the ages of rocks.

# data[].attributes.body
I think they use them to tell if they are more older or if there younger.

# data[].attributes.body
They use the law of superposition to tell how old rocks are.

There are layers from the rock cycle and they check which layer it's in to see how old it is.

The deeper the rock, the older it is.

# data[].attributes.body
The law of superstition states that that each layer of rock is younger than the one below it and older than the one above it. So if they know the relative age of one layer they can estimate the ages of the other layers using this method

# data[].attributes.body
Geologist use the law of superposition to tell the ages of rocks by looking at the layers of rock. The law of superposition said that the youngest layer of rock is on top and the oldest layer of rock is in bottom. Each layer is younger than the one beneath it and older than the one above it. We can look at different layers and know how old it is by looking at where it is.

# data[].attributes.body
Geologists use the law of superposition to tell the ages of rocks and fossils by looking at their position in the layers of the earth. The law of superposition states that the youngest layer of rock is on top and the oldest on bottom, each later being younger than the on beneath it and older than the one above it. So the geologists can look at different layers of rock and know how old it is by looking to see where it is located.

They use it to measure the age of the rock by knowing the youngest layer of rock is on top and the oldest layer is on bottom

# data[].attributes.body
If they find out the age of one layer it may help them find out the other ages of the other layers.

# data[].attributes.body
Youngest layers are on top are oldest layers are on bottom, each layers being younger than the one beneath it.

# data[].attributes.body
They look at how far the rock is from the surface.

The farther down the rock is the older it is and the closer it is to the surface the younger it is.

This is my reasoning is that that are both the same.

# data[].attributes.body
They use it to measure that age of the rocks by the distance they are underground. The farther from the surface you get the older they are.

# data[].attributes.body
Geologist use the law of superstition to tell theage  of rocks.
Because they know that the youngest layer is on top and the older on bottom, each layer being older than the one on top of them.
This is my reasoning

# data[].attributes.body
They use the law of superpo  too tell if the fossils and rock is older or younger. Also they use it to tell the age.

# data[].attributes.body
They look at the distance of the layer from the top

It says in the book the top is youngest
Bottom is oldest

My reasoning is that both of those statements mean the same

# data[].attributes.body
They use it by seeing which of the oldest fossils are on bottom and the youngest on top. They have proven the oldest fossils r on bottom through science. And that the youngest r on top through science

# data[].attributes.body
They use it to by saying that the layer above the bottom layer is younger than the one below it but other they the one above. They can tell how old fossils are by looking at which layer it was found

# data[].attributes.body
My claim is that geologist use the 'law of superposition' to tell the ages of rocks and fossil by their position in layers of the earth. My evidence is rocks that are higher in the ground, or out of the ground, are younger that lower layers of rocks. My reasoning is rocks form in layers of different materials and are always younger than the layer below, and older than the layer above.

# data[].attributes.body
They use it to by saying that the layer above the bottom layer is younger than the one below it but other they the one above.
Read a book or two in science
It just is.

# data[].attributes.body
To give an age of a rock

# data[].attributes.body
They use the law of superstation to know how they are. They find out by how far down below the crust. They dig deep down in the earth and they find big rocks and fossils. They use big drills to dig deeper then mankind.
