False
A river flowing across the rocky surface of the earth could create which of the following? A Dunes B Mountain C Canyon D Hill
Canyon
Any process that breaks rocks down into smaller pieces.
What is weathering?
1.Fossils give us evidence about which of the following? A Plants and animals that lived long ago B How weathering and erosion break down rocks C The other planets in our solar system D The transfer of energy from one form to another
Plants and animals that lived long ago
A valley formed by a glacier
What is a U-shaped valley?
A paleontologist finds a fish fossils in rocky mountain area it tells them...
there was water there once
How could students best model the formation and movement of dunes? A Pour water over piles of sand B Slowly drip wet sand into a tub of water C Use a spoon to dig a hole in a tray of sand D Use straws and blow piles of sand
Use straws and blow piles of sand
Sand dunes are formed by this
What is wind?
1.Finding the fossils of trees in an area that is currently a desert without much life might tell us that the area, millions of years ago – A was heavily eroded by strong winds B received enough rain to support a forest C suffered very powerful earthquakes D was destroyed by the impact of meteorites
received enough rain to support a forest
The build up of land by depositing sediment and soil in a new location.
Deposition
Some wooly mammoth fossils have been found still having fur, that means they were fossilized in...
What is Ice?
Canyons and deltas are similar in that both form-
Due to the action of moving water
The movement of pieces of rock from one place to another.
What is erosion ?
1.Several wooly mammoth fossils have been found. Mammoths, which lived hundreds of thousands of years ago, were covered with thick fur. Based on this evidence, mammoth fossils tell us that the area in which they are found – A has too many humans B no longer has large animals C was, at one time, very cold D receives more rain than it used to
was, at one time, very cold
Cause rapid changes in the earth's surface by making cracks in the crust and changing landforms
What is a Earthquake?
When layers of sediment are squeezed together.
What is compaction?
What natural force formed the Grand Canyon by slowly cutting through the rock over many millions of years? A A boulder B A glacier C A river D A landslide
A river
A landform formed at the mouth of a river
What is a delta?
1.If a scientist is seeking rocks that formed at the mouth of a river, the fossils of which of the following would be the best evidence that rocks were formed under these conditions? A Freshwater birds B Large animals C Flying insects
Freshwater birds
Cause rapid changes to the Earth's surface by creating new land or changing landforms
What is a Volcano?
Most fossils are found in
What is sedimentary rock?
A delta forms where the river meets the ocean because the ocean - A makes the river slow down and deposit sediments B contains salt water and the river contains fresh water C is usually much colder than the water in the river D has powerful currents that weathers the rock on the shore
makes the river slow down and deposit sediments
When pieces of rock are dropped and no longer moving.
What is deposition?
Which of the following could be evidence that a forest was covered by water millions of years ago? A Sand B Fossils of fish discovered in rocks below the forest C Insects living in the forest that lay their eggs in the water D An increase in rainfall in the forest over time
Fossils of fish discovered in rocks below the forest
Cause rapid changes to Earth's surface by rocks and debris falling from a rock face
What is a landslide?
