The windward mountain slope generally receives:
A. More precipitation than the leeward slope
B. Always less precipitation
C. No clouds
D. No erosion
Correct Answer: A
Orographic uplift makes windward slopes wetter in many climates.

Orographic rainfall is enhanced when moist air:
A. Rises over mountains
B. Descends into valleys
C. Moves over flat desert only
D. Stops moving
Correct Answer: A
Forced ascent cools air and promotes condensation and precipitation.

A rain shadow commonly develops on the:
A. Leeward side of a mountain range
B. Windward side only
C. Ocean floor
D. River bed
Correct Answer: A
Descending leeward air warms and dries after moisture loss on the windward slope.

Isostatic rebound can occur after:
A. Erosion removes mass from mountains
B. Rainfall increases
C. Magnetic reversal
D. River freezes
Correct Answer: A
Unloading permits lithosphere to rise toward gravitational equilibrium.

Crustal thickening promotes mountain uplift partly through:
A. Isostasy
B. Evaporation
C. Coriolis force
D. Ocean tides
Correct Answer: A
Thick low-density crust has a deeper root and greater surface elevation.

An orogenic belt is commonly associated with:
A. Convergent plate margins
B. Passive margins only
C. Stable ocean basins
D. Desert dunes
Correct Answer: A
Convergence drives deformation and mountain building.

Orogeny means:
A. Mountain-building process

A butte is generally:
A. A smaller isolated flat-topped remnant than a mesa
B. Larger than a continent
C. A river delta
D. A fold axis
Correct Answer: A
Continued erosion can reduce mesas to smaller buttes.

A mesa is:
A. A flat-topped, steep-sided erosional remnant larger than a butte
B. A deep sea trench
C. A volcanic pipe only
D. A glacial lake
Correct Answer: A
Mesas are capped by resistant strata and left by differential erosion.
