Based on your observations, how is Sedimentary rock formed?

Each of the pictures below

contains a sedimentary rock

formation on Earth.

As you view each image, answer the

questions.

From atop of its
peaks, sedimentary
rock just looks like
“GROUND”... but
when erosion lets us
peek at what is
underneath, a new
story is revealed.

Multiple Choice

The layers in these rock formations are straight, as if the sediment was laid down one layer right on top of the other, but the rocks seem to have been worn away. What likely weathered down the rocks in this formation?

• Wind

• Water

• Earthquakes/ Mountain Building

• Ice

Multiple Choice

The layers in these rock formations are tilted and disrupted. How do you think an entire section of ground could be dislodged? Hint: this would be too much work for wind or water.

• Wind

• Water

• Earthquakes/ Mountain Building

• Ice

Multiple Choice

The layers in these rock formations appear “swept” with very smooth lines below a certain level. What likely created these smooth patterns?

• Wind

• Water

• Earthquakes/ Mountain Building

• Ice

Multiple Choice

When rock is eroded away and leaves a strange shape behind, it indicates that the rock that is left behind was stronger or harder than what was worn away. What likely removed weak rock to leave this formation behind?

• Wind

• Water

• Mountain Building/ Earthquakes

• Ice

Open Ended

In this image, the erosive force is pictured… WATER! Not all the rock is gone, leaving "pillars" behind in the sea. Why would some rock still be left behind?

Multiple Choice

Erosive agents are working underground as well. What agent created this cave in Kentucky?

• Wind

• Water

• Mountain Building/ Earthquakes

• Ice

Answer the next
question on the last slide.

Multiple Choice

Sediments that are transported by water end up where?

• at the top of a stream

• at the bottom of a stream

• in a random new location

Multiple Choice

Sediments that are transported by wind end up where?

• At the top of a stream

• In a random location.

• Somewhere else - depending on wind velocity & sediment size.
