I noticed that the layers get a little brighter as they get to the top in some of the images.

# data[].attributes.body
I noticed that there are a lot of layers of rock in the Grand Canyon.

# data[].attributes.body
I noticed that the walls of the Grand Canyon were multicolored because of the minerals.

# data[].attributes.body
I noticed that the Grand Canyon has different layers of colors, from oldest to youngest

# data[].attributes.body
What I noticed about the walls at the Grand Canyon is the different colored walls. How much time does it take for canyons to form

# data[].attributes.body
I found that there are layers and diffrent colors of rock. Can the walls get bigger? the older rocks are darker.

# data[].attributes.body
The question i have is why are there many layers of rocks in the grand canyon.

# data[].attributes.body
I think that there are many layers of rock because of the heat and erosion

# data[].attributes.body
The questions I have are how old is the oldest layer of rock 2

# data[].attributes.body
I noticed that each layer from the grand canyons are color coded from the oldest layers to the youngest layers of the grand canyon

# data[].attributes.body
A question I have is why are Grand Canyons so high.?

# data[].attributes.body
I notice the walls of the Grand Canyon are different colors and there are different layers of rock.

# data[].attributes.headline
A question I have is will the grand canyon be higher then now?

# data[].attributes.body
What I noticed about the walls of the Grand Canyon is rocky and big, and they have middles to them.

# data[].attributes.body
The layers can tell me that maybe which one is the oldest or a couple and which one or a couple are the youngest.

# data[].attributes.body
I think its cool that every layer is a different layer than the first one

# data[].attributes.body
One question I have is that why ar

# data[].attributes.body
The layers of the Grand canyon tell me which ones are the oldest, and the ones that are the youngest

# data[].attributes.body
I notices that the walls of the Grand Canyon are covered in rocks. But I also noticed in a bit of moss.

# data[].attributes.body
A question I have is how old is the Grand Canyon?

# data[].attributes.body
I noticed there are lots of different lines along the rocks. These are probably from erosion. This can also tell us how old the rock is.

# data[].attributes.body
I think that the walls are made out of, rock, of course. But also maybe a lot of dirt / mud. This might hold all the rocks together to create these amazing walls of greatness. So i think the Grand Canyon is made out of dirt/mud, and rocks.

# data[].attributes.body
I think that each layer of rock can tell us how old they are,

# data[].attributes.body
My question is, how exactly did all the rocks get all set up like that to make the Grand Canyon.

# data[].attributes.body
I notice that each wall is made up of all these little, tiny rocks.

# data[].attributes.body
The different layers present how old they are.

# data[].attributes.body
What the grand canyon's wall could be mead out of is rock and fossils

# data[].attributes.body
What the different layer represents is how old is that layer

The layers can tell us that the bottom layer is the oldest, and the the top layer is the youngest.

# data[].attributes.body
One question that i have is who built the trails? How long ago were they built?

# data[].attributes.body
What I notice about the walls of the Grand Canyon is that the layers are different colors, so maybe the layers are made out of different materials.

# data[].attributes.body
I think that erosion created and changed the grand canyon.

# data[].attributes.body
One question I have is that why are the Grand Canyon's layers different colors?

# data[].attributes.body
I think erosion from thousands of years made the layers to the canyon.

# data[].attributes.body
I think the layers can tell us how many years the mountain or rock has been there or standing.

# data[].attributes.body
I think the different layers of rock can tell us how old each layer is.

# data[].attributes.body
I think that erosion from the rocks made the layers.

# data[].attributes.body
One question I have is how does the Grand Canyon gets its colors.

# data[].attributes.body
I think the layers might mean how old the grand canyon is

# data[].attributes.body
One question I have is how did the walls of the canyon get so tall. ( or the canyon so deep ) Another question I have is why are there so many walls?

# data[].attributes.body
I think what could of made the layers of rock was erosion.

# data[].attributes.body
one question I have about the grand canyon walls is why are they those colors.

# data[].attributes.body
A few things that could have made the Grand Canyon could be fossils, animals and people.

# data[].attributes.body
The layers can probably tell us how old the Grand Canyon is.

# data[].attributes.body
What I noticed about the grand canyon walls is that most of the time the walls are high above on each side so the canyon is very deep. Also the different colors of the rock

# data[].attributes.body
What I noticed about the Grand Canyon walls is that there all different colors (orange, red, brown, peach) Also what I noticed about the Grand Canyon is that each platoe is at a different height.

# data[].attributes.body
what I noticed about the walls of the grand canyon is all the colors.

# data[].attributes.body
One question  I have about the walls of the Grand Canyon is why are they different colors?  Is it because they are made of different rocks?

# data[].attributes.body
I notice that the walls layers are  different colors, for example, some can be peach, brown or maybe even red!

# data[].attributes.body
I think the layers were made by erosion

# data[].attributes.body
A question I have is how did the different layers of rock form ?

# data[].attributes.body
I think the layers tell us that how old it they are

# data[].attributes.body
What I think that could have made the layers is the weather because the weather can melt and destruct rock and other landscapes.

# data[].attributes.body
one question I have is how did the river in the canyon get there

# data[].attributes.body
one question I have is how are the color of the rocks that color

# data[].attributes.body
What I notice about the walls of the grand is that they are different colors. For example some are peach.

# data[].attributes.body
I think the different layers of rock show us how long the rock has been there.

# data[].attributes.body
What I notice about the grand canon wall is that the rocks are different color.

# data[].attributes.body
I notice that on the walls of the grand canyon there are diffrent layers

# data[].attributes.body
the question i have is why is there different colors on the rocks.

# data[].attributes.body
I think what might have made the layers is maybe rocks were placed there, and over time, due to the sun, it melts and dries and makes the rocks into a layer of the Grand Canyon we see today.

# data[].attributes.body
A question I have is, why is there a different color on each layer? (Only appears like that in some pictures)

# data[].attributes.body
Things that could have made the layers are animals, fossils, bugs, and people.

# data[].attributes.body
I think the different layers of rock can tell us how long they have been here and the scientists can tell how long the mountain was there.

# data[].attributes.body
The layers can tell us how long it has been around.

# data[].attributes.body
Questions I have for the walls of the Grand Canyon are why are there different colors on the walls?

# data[].attributes.body
What I notice about the walls of the Grand Canyon is that they have a small variety of colors with only one on each layer.

# data[].attributes.body
what I notice about the walls of the Grand Canyon is bumpy, orange green rocky. And there are also different shades of orange, green, black, and red.

# data[].attributes.body
The layers can tell us how old the Grand canyon is because the oldest layer a.k.a the first layer is about how old the Grand canyon is.

# data[].attributes.body
what I notice about the walls of the grand canyon is that they are all the same color but VERY different shades.The bottom one looks the oldest (like it is).And the top rock looks newer (like it is),

# data[].attributes.body
A question I have is how did the different layers of rock get on top of each other.

# data[].attributes.body
What I notice about the walls of the Grand Canyon is they are all different colors most of them are different shades of red or orange.
