The breaking down of rock on Earth's surface into smaller pieces.
weathering
what replaces the soft parts of an organism when they turn into a fossil?
sedimentary rocks, minerals, or sediment
Scientists may learn what an animal ate by looking at the shapes of this fossil item.
the type of teeth they have
Mountains, deltas, sand dunes, and canyons
landforms
what are fossil fuels made out of
old living tissues of organisms
The process by which weathered rock is picked up and moved to a new place.
erosion
Animal fossils are more common than plant fossils because plants have this.
softer body parts
if we see a shell type fossil in a mountain what does that tell us about the mountain?
It was once covered up by water
Huge sheets of ice that move slowly over land
glaciers
what is the process called, when rocks and minerals are moved and placed to a new location forming new landforms,
deposition
Wind and water can carry sand and small pieces of rock to new locations. True or False
true
We do not know what many ancient plants look like because they did this before they could form a fossil
rotted away, decomposed, or decayed
if a fossile is in the lowest layer of sedimentary rocks, is the fossil old or young?
old
large streams of water that flow across land
rivers
Suppose a plant and animal die on the same day. Which one will most likely become a fossil? Why?
The animal because it has more hard parts than the plant
Name a difference between weathering and erosion.
weathering makes things smaller, and erosion moves it
Fossils are usually found in this type of rock
sedimentary rock
If two fossils are found in the same rock, scientists can infer that these two things did this.
lived at the same time
How can you tell which layer is oldest?
By looking at the different colors, one can assume/infer that the bottom layer is the oldest
Landslides are quick changes to the land. They can be caused by: A. magma and rain B. gravity and rain
gravity and rain
All of the following are forces that change landforms EXCEPT: a. wind b. moving water c. glaciers c. physical features
physical features
Describe the steps for a fossil to form in sedimentary rock.
1) soft parts of the animal decompose 2) hard parts of the animal are buried under layers of sediment 3) the bones and sediment turn into rock
By looking at a fossil jawbone you may learn
what the animal ate, female or male
what caused this?
weathering
Why is using fossil fuels not a good solution to our energy problem?
it is non renewable resource and causes a lot of pollution
