Preserved parts or traces of animals and plants that lived in the past are called
deposition
erosion
fossils
Erosion is one of the processes involved in the formation of sedimentary rock. Which of these best describes the process of erosion?
Rocks are broken into smaller pieces that remain in the same location.
Pieces of rock or soil are carried from one place to another.
Pressure compacts layers of sediment and turns them into rock.
Sediment grains fall to the bottom of a lake to form sedimentary layers.
How are fossils created?
Dead organisms are quickly buried for millions of years.
Traces of organisms get turned into stone.
Animals get trapped.
All of the above
Sedimentary rocks form when broken bits of other rock are deposited and then -
buried and squeezed and cemented together
melted by the heat of the Earth's core
completely dissolved in the salt water of the ocean
used by humans as a natural resource
Which of the following is NOT something you could learn from a fossil?
What the animal ate
The size of the animal
Where the animal lived
The color of the animal
Which of the following fossil discoveries best demonstrates a change in the Earth's surface?
Scientists discover a large number of footprints of different sizes
Scientists discover fossils of underwater organisms in an area of dry land.
Scientists discover fossils of straight teeth buried below fossils of curved teeth.
Scientists find an area that contains a variety of plant fossils but no animal fossils.
Scientists found an index fossil in layer Z that was about 400 million years old. They determined that in that area, a new layer of earth was deposited every 50 million years. If a fossil was found in layer W, how old was the fossil?
less than a million years old
about 300 million years old
about 100 million years old
over 400 million years old
Scientists began to dig in a new location where there are many layers of artifacts and fossils. Today, archaeologists reached the lowest layer and discovered fossils of fish bones and plants there. What might have been in this area many years ago before all of the other layers of fossils came into being?
water
desert
mountains
restaurants

This is a picture of the layers of rock from North Dakota. What can you conclude based on these layers? Choose 2.
This area was covered by water at one time.
Energy from the sun was less in this area a long time ago.
The animals in the area have changed over time.
Fishes are older than trilobites.
What is a fossil?
A fossil is the preserved remains or impressions of a living organism such as a plant, animal, or insect.
A fossil is a type of rock formed from volcanic activity.
A fossil is a rare type of gemstone found only in certain regions.
A fossil is a type of mineral used in jewelry making.
What are the two main types of fossils?
Body fossils and trace fossils.
Igneous fossils and sedimentary fossils.
Mineral fossils and organic fossils.
Primary fossils and secondary fossils.
Where are most fossils found?
Most fossils are found in sedimentary rock such as shale, limestone, and sandstone.
Most fossils are found in igneous rock such as granite and basalt.
Most fossils are found in metamorphic rock such as marble and slate.
Most fossils are found in volcanic rock such as pumice and obsidian.

Evan worked on 2 tracks for his car. The tracks had different slopes. The dashed lines on the track represent how far the car traveled. Why did Jack’s car go farther on slope 2?
The car had less speed and energy at the bottom of slope 2.
The car had more speed and more energy coming down slope 1.
The car had less speed and less energy coming down slope 1.
