According to standard geological definitions, a mountain range is characterized as a collection of mountains that are not necessarily arranged in a linear fashion.
Answer: False
Explanation: Geological definitions posit that a mountain range is a series of mountains or hills arranged in a line and connected by higher ground, distinguishing it by its linear arrangement.
A mountain system is a smaller, more specific classification than a mountain range.
Answer: False
Explanation: A mountain system or belt represents a broader classification, encompassing multiple related mountain ranges that originate from the same geological event, whereas a mountain range is a more specific linear feature.
Natural geographical features like rivers and canyons are the primary means by which individual mountain ranges are segmented.
Answer: False
Explanation: While rivers and canyons can be present within mountain ranges, the primary segmentation is typically achieved by features such as highlands, mountain passes, and valleys.
All mountains within a single mountain range are geologically identical, sharing the same rock composition.
Answer: False

Erosional forces work to build up mountain ranges over geological time.
Answer: False
Explanation: Erosional forces, such as weathering and mass wasting, act to wear down and reduce the elevation of mountain ranges over geological time, rather than building them up.
Sediments eroded from mountains are transported and deposited in basins, eventually forming sedimentary rock.
Answer: True
Explanation: Material eroded from mountains is transported to basins, where it accumulates as sediments. Through geological processes of burial, compaction, and cementation (lithification), these sediments transform into sedimentary rock.
The early Cenozoic uplift of the Rocky Mountains led to the deposition of sedimentary strata onto the mountain core.
Answer: False
Explanation: During the early Cenozoic, the uplift of the Rocky Mountains was accompanied by the erosion of sedimentary strata *from* the mountain core, with this material being deposited onto adjacent regions like the Great Plains.
Computer simulations suggest erosion rates increase significantly when mountain belts become tectonically inactive.
Answer: False
Explanation: Computer simulations indicate that erosion rates tend to decrease, rather than increase, as mountain belts transition from tectonically active to inactive states, due to factors like reduced landslide frequency and fewer abrasive particles.
Isostatic adjustment can cause the Earth's crust to rise in response to the removal of weight through erosion.
Answer: True
Explanation: Isostatic adjustment refers to the vertical movement of the Earth's crust in response to changes in load. The removal of mass through erosion can indeed cause the crust to rebound upwards.

Mountain ranges have minimal impact on regional climate patterns.
Answer: False
Explanation: Mountain ranges exert a substantial influence on regional climate patterns by acting as barriers to air masses, thereby affecting temperature and precipitation distribution.
Orographic precipitation occurs on the leeward side of a mountain range.
Answer: False
Explanation: Orographic precipitation, the release of moisture due to air ascending mountain slopes, occurs predominantly on the windward side of a mountain range. The leeward side is typically characterized by drier conditions and a rain shadow effect.
A rain shadow is an area of high rainfall on the windward side of a mountain range.
Answer: False
Explanation: A rain shadow is defined as an area of significantly reduced rainfall located on the leeward side of a mountain range, resulting from descending, dry air.
Large mountain ranges can act as barriers, dividing continents into similar climate regions.
Answer: False
Explanation: Large mountain ranges function as barriers that divide continents into distinct climate regions, rather than promoting uniformity, by influencing air mass movement and precipitation patterns.
The adiabatic lapse rate describes the process of air cooling and releasing moisture on the leeward side of a mountain.
Answer: False
Explanation: The adiabatic lapse rate describes the rate of temperature change in air due to compression or expansion. While it influences air temperature on mountain slopes, the cooling and moisture release primarily occur on the windward side, with warming and drying on the leeward side.
What is the primary mechanism by which mountain ranges influence regional climate?
Answer: By blocking or diverting air masses, affecting precipitation patterns.
Explanation: Mountain ranges significantly influence regional climate by acting as barriers that block or divert air masses, thereby altering precipitation patterns and temperature distributions.

Answer: Orographic precipitation
Explanation: Precipitation that results from moist air being forced upward over mountain slopes is termed orographic precipitation.
What climatic phenomenon is typically observed on the leeward side of a mountain range as a consequence of descending, dry air?
Answer: A rain shadow effect
Explanation: The leeward side of a mountain range often experiences a rain shadow effect, characterized by reduced rainfall due to descending, dry air.
How do extensive mountain ranges, exemplified by the Andes, influence continental climate patterns?
Answer: Acting as barriers that compartmentalize continents into distinct climate regions.
Explanation: Large mountain ranges function as barriers that divide continents into distinct climate regions, rather than promoting uniformity, by influencing air mass movement and precipitation patterns.
