• Internal geological processes

• External geological processes

• Non geological processes

• Option 1 and 2 are correct

The atmosphere is a :

• Internal geological process

• External geological process

• Isn´t a geological process

• None of them are correct

The mechanical effect of disintegration of rocks with no chemical change is called:

• Biological weathering

• Erosion

• Physical weathering

• Chemical weathering

Is the wear down, rip off and mobilization of material produced by wind or water.

• Meteorisation

• Sedimentation

• Transportation

• Erosion

In the erosion. The more tilted the area is, the more erosion due to gravity. We are talking about:

• Sum

• Slope

• Speed

• Surface

It is the displacement or moving of the sediments (eroded material) from one place to another one. We speak about:

• Meteorisation

• Erosion

• Transportation

• Sedimentation

"Heaviest and irregular shaped particles creep along the ground when the agent is strong enough" This process is:

• Saltation

• Suspension

• Sliding

• Rolling

"The bigger and rounded particles roll on themselves when the agent is strong enough". We are speaking about:

• Sliding

• Saltation

• Rolling

• Suspension

The linear and barchane dunes are typical of:

• Rocky deserts

• Reg deserts

• Erg desert

• Badlands

What is this picture?

• Natural arc

• Taffoni

• Mushroom shape rocks

• Meandres
