What kind of fossils would you find below a forest that would lead to the conclusion that the area long ago had a large lake?
100
Going from a higher elevation down to oceans and lakes.
What cause rivers to move?
100
They take millions of years to form.
Why do we need to conserve fossil fuels?
100
Wind moves the sand.
Why do sand dunes move?
200
Sedimments form into layers of rock adn are deposited on the ocean floor, river bottoms, and lakes.
What is the process that leads to the formation of sedimentary rocks?
200
The plants and animals that lived long ago.
Fossils are best used as evidence for what?
200
Moving water slows down.
A delta is formed when____________________.
200
They provide energy needed by fossils.
Why are coal, oil, and natural gas called fossil fuels?
300
The bottom layer.
What layer will you find the oldest fossils?
300
Rivers deposit new material on the delta.
How do deltas grow (or get larger)?
300
They cannot be reused/renewed.
What are fossil fuels called nonrenewable resources?
300
They eat unwanted bugs.
How can we benefit from bats?
400
Because these plants and animals have been buried in sediments for the shortest amount of time.
Why is the youngest fossil found on the top layer?
400
Wind, water, ice, and animals
How can nature change the Earth's surface?
400
They settle to the bottom and are buried in sediments.
How are oil formations made after the organisms in the ocean die?
500
The water slows down and sediments fall out.
Why do deltas form where rivers empty into the ocean?
500
Lots of plant life and rapid laying down of sediments.
