Question

which of the following describes why highland regions are colder than the surrounding regions?
highland areas are far from large bodies of water.
temperature decreases with altitude.
highland regions are found in higher latitudes.
ocean currents stabilize the climate in highland regions.

Explanation:

The key concept here is the relationship between altitude and temperature. In the Earth's atmosphere, as altitude increases, the temperature generally decreases. Highland regions have higher altitudes compared to the surrounding lower - lying areas.

• The option "Highland areas are far from large bodies of water" is more related to the concept of maritime vs. continental climates (where proximity to water can moderate temperature) rather than the temperature difference due to altitude.
• The option "Highland regions are found in higher latitudes" is incorrect because highland regions can exist at various latitudes. For example, there are high - altitude regions near the equator (e.g., the Andes in South America which straddle the equator in some parts).
• The option "Ocean currents stabilize the climate in highland regions" is also incorrect. Ocean currents mainly affect coastal climates and do not explain why highland regions (which may be inland) are colder.

Answer:

Temperature decreases with altitude.
