True or false…

Erosion occurs when rocks are not moving…







The rich topsoil of the prairie in the picture shown makes this

ecosystem suitable for the growth of a variety of grasses. All of

the following processes contribute to the formation of the topsoil

in the prairie except —

A weathering of rocks

B ocean waves

C deposition of weathered material

D decomposition of living things



_______is the most important erosional agent and this

erodes most often in streams or rivers.


Water thisis the most important erosional agent and

erodes most often in streams or rivers.


A hurricane forms over the ocean and hits the Texas coast and travels inland. What is the most likely effect of this event?

A More species of animal will inhabit the coast

B The shape and size of beaches will be changed

C The affected area will be less vulnerable to future natural disasters

D Native plants will never inhabit the area again


B and travels inland. What is the most likely effect of this event?The shape and size of

beaches will be changed


When the scooter hits a rock, the rider tends to fly forward because –

A objects at rest tend to stay at rest

B the scooter is subjected to a balanced force

C a force opposes the motion of the scooter but not the rider

D unbalanced forces cause objects to move at a constant speed


C. because – a force opposes the motion of

the scooter but not the rider


Which of the following is a force because –

that can oppose or change motion?

A. gravity

B. air resistance

C. friction

D. all of the above


D because –. all of the above


Force because –

  • The diagram above illustrates a movable pulley. This pulley gives a mechanical advantage by -

    • A reducing the force required to lift the load.

    • B changing the force direction

    • C requiring the force to be greater than the load

    • D requiring the force to move less distance than the load

Load


  • A. because – reducing the force required

  • to lift the load.


The picture shows a simple fixed pulley being used to lift a heavy box.

Which of these does the pulley change?



Chemical weathering happens quickly in heavy box.

______, _______environments because

water is needed for the chemical reactions.


warm, moist heavy box.


In chemical weathering, a rock is broken heavy box.

down by ______ ______that change its

mineral composition and physical

and chemical properties


chemical reactions heavy box.


True of False: heavy box.

Water can chemically weather rocks by

dissolving rocks.


True heavy box.


True of False: heavy box.

Living organisms such as Lichens do not chemically weather rocks.


False heavy box.


True of False: heavy box.

Rust is a form of chemical weathering


True heavy box.


Mechanical weathering: heavy box.

__________ breaks rocks down into smaller pieces


physically heavy box.


True or False: heavy box.

Weathering happens to rocks that are moving.


False heavy box.






What is abrasion? smaller pieces




Plucking sediments off of the ground?


How can wind be a cause of erosion? sediments off of the ground?



What happens to rocks and sediment that are plucked by glaciers whenever the glacier melts?


The rocks and sediment are deposited glaciers whenever the glacier melts?

in a new location.


Describe how waves in the ocean can cause erosion. glaciers whenever the glacier melts?




Gravity! after time
