Unit 2 Summative Fossils, Rock Layers and Natural Resources

MOM, can we go PLEASE?” Ryan begged as he was looking at the museum booklet for the new fossil exhibit.

“We have tickets for 3:00 today. Why don’t you eat some lunch and get ready to go?” Mom said.

Ryan raced to the kitchen and gobbled down some dinosaur shaped chicken nuggets. Soon it was time to leave for the History Museum. He was so excited to see all of the dinosaurs and fossils that were millions of years old.

When Ryan entered the door of the museum it was as if he was stepping back in time…

1. Ryan had learned that Earth's surface has changed over time. What evidence has been collected by scientists to support this theory?

• Ancient people left photographs of Earth's surface behind for scientists.

• Fossils have been found that give clues to what Earth's surface looked like many years ago.

• Paleontologists have studied Earth's surface in the past and present and see no changes

• We do not know what Earth's surface looked like long ago

Fossil evidence provides scientists with information about...

• how an environment has changed over time.

• rocks and minerals.

• where earthquakes occur.

• how mountains form.

As Ryan and his mom walked through the museum the walls transformed into a model of the Grand Canyon. The layers were so many different shades of red and brown.

“This is AMAZING!” Ryan cried as he looked from the floor to the ceiling.

The story of the Grand Canyon is written in all of its beautiful rock layers. They were formed millions of years ago. Geologists study the layers to discover the history of the area.

Where are the oldest rocks of the Grand Canyon?

• At the top of the mountain

• Where the darker rocks are located

• At the bottom of the mountain near the river

• Where the lighter colored rocks are located

Several layers of rock are illustrated in their unchanged positions. Which of the following conclusions is supported by the data in this illustration?

• Rock layer W is the oldest of all the rock layers shown.

• Rock layer X was formed just before rock layer Y.

• Rock layer Y is twice as old as rock layer W.

• Rock layer Z is the oldest of all the rock layers shown.

As Ryan began looking closely at the model layers of the Grand Canyon, he noticed what looked like animals in some of the rocks.

“MOM! LOOK! There are fossils in the rocks!” Ryan shouted.

“Shhhh, not so loud. Let’s see what we can learn about them,” mom whisperd.

Look at the picture of the fossils found in the layers Ryan saw.

Based on the evidence shown, what was the most likely environment of these organisms?

• The environment was most likely covered in rock.

• The environment was most likely cold and icy.

• The environment was most likely underwater.

• The environment was most likely dry and hot.

Ryan’s mom saw him trying to read a chart on the wall.

Mom explained, “A geologic time scale is like a calendar of events that shows events in Earth’s history.”

The chart shows a geologic time scale.

The oldest fossils from the chart above are from which TWO Rock Layers?

• Layer B

• Layer C

• Layer D

• Layer E

• Layer F

The fossils of clams, which live at the seashore, were found in a rock layer directly below a rock layer that contained tree fossils. This evidence can be used to support the idea that

• Fossils form more quickly at the seashore than other places.

• Clams and trees are always found in the same area.

• The area where the fossils were found changed over time.

• The layer containing the trees is older than the clam layer.

Ryan and his mom continued to walk through the Grand Canyon exhibit. They found a wall that was labeled with layers A - F.

Make a claim about how patterns in a canyon rock formation provide evidence of changes in a landscape over time. Support your claim with evidence from the picture below.

Ryan and his mom continued past the Grand Canyon exhibit to the Natural Resource Science Center. Sam had been learning about different types of energy sources in class. He remembered reading about fossil fuels and alternative energies and he was excited to share this information with his mom.

Most of the energy that we use today comes from the burning of nonrenewable fossil fuels like coal, natural gas and oil. Which of the following statements best describes a negative impact caused by burning the fossil fuels?

• We can cut down the trees and they grow back in a short amount of time.

• We burn coal to produce electricity for our homes and by doing so, we release Greenhouse Gases back into the atmosphere.

• We have built solar panels to place on the roofs of homes to capture the sun’s light energy to heat our homes.

• We have built dams to use the power of moving water to create electricity.
