Question

which physical processes are responsible for — a. canyons: __ b. mountains: c. new landforms because of cooled lava: d. formation of bedrock and layers of new land: e. formation of sand dunes: tectonic plates cause __, earthquakes, mountains and creation of new land.

Explanation:

a. Canyons:

Erosion (water/ice flow) carves canyons.

b. Mountains:

Tectonic plate collision (orogeny) forms mountains.

c. New landforms (cooled lava):

Volcanic activity (lava solidifies) creates new land.

d. Bedrock/layers (new land):

Sedimentation (deposition, compaction) forms bedrock layers.

e. Sand dunes:

Wind erosion/deposition (aeolian processes) forms sand dunes.

Tectonic plates cause:

Plate movement (convection currents) causes earthquakes, mountains, new land.

Answer:

s:
a. Erosion (e.g., river/water flow)
b. Tectonic plate collision (orogeny)
c. Volcanic activity (lava cooling)
d. Sedimentation (deposition + compaction)
e. Wind erosion/deposition (aeolian processes)
Tectonic plates cause: Plate movement (convection - driven)
