Which event marks the end of Precambrian time?
first animals with exoskeletons appear

What happens to a rock when it is weathered?
- It is broken into smaller pieces.

True or False? Erosion moves rocks without breaking them down
True
400
Name an agent of weathering.
wind water ice
400
Name one way weathering can take place.
Roots growing into rocks, ice wedging, moving water.

weathering
400
Leaves release acids into the soil as they decay. How could the decaying leaves affect the rocks in the soil underneath them?
They could increase the amount of chemical weathering.
400
What will happen to the rock and the plant over time?
The plant will grow, and the crack will get bigger.
500
The movement of weather material on the Earth's surface by wind water or ice
Erosion
500
Rocks in fast-moving water bump into each other, eventually they will become
Smaller and/or smoother
500
Which are the main causes of crack growth in rocks over time?
Plant growth and ice wedging
500
Name a landform created from moving water.
Canyon or Valley,

Explain why trace fossils are more common than body fossils.
A single animal can leave thousands of traces in its lifetime but will leave only one body when it dies
500
This landform is a result of deposition since it leaves a solid material behind. A river slows creating a ________.
delta

.
What type of physical evidence is shown in this figure?
A fossil
600
River A flows downward at an angle of about 45 degrees. Underground River B flows downward at an angle of about 60 degrees. What can you conclude about the erosion rate of each river?
River B rocks erode faster because it has a steeper incline.
600
What often happens to rocks that undergo chemical weathering?
They crumble easily
600
Equal amounts of gravel were placed on four trays. the trays were then set at different angles and a garden hose was used to keep the water running at a steady rate down each tray. They recorded the following data:
Summarize the results of the experiment?
Steeper slopes cause water erosion to occur more quickly
600
What event most likely contributes to gradual underground cave formation?
A flood.
600
What can scientists learn by studying ice cores?
What is the history of Earth's climate?
700
This word is most closely associated with uniformitarianism.
gradual
700
Earth’s surface features slowly change over time. For example, sharp, jagged mountain ranges become lower and more rounded over time. What factor or factors is/are responsible for this change in their shape?
Weathering and erosion.
700
Tanya observed a narrow and steep valley with a stream at the bottom of it. What most likely caused the valley to first form?
Running water.
700
What geologic change is shown in the figure?
Erosion
700
The alluvial fan shown in the following illustration formed as sediment began to drop out from a stream that could no longer carry all of its sediment.
Please explain why the stream could no longer carry all its sediment?
The speed of the water is too slow.

about how old is Earth?
About 4.6 billion years old.
