A semi-arid climate is also commonly referred to as a semi-desert climate or a steppe climate.
Answer: True
Explanation: The source explicitly states that a semi-arid climate is also known as a semi-desert climate or a steppe climate.
Forests are the predominant vegetation type found in semi-arid climates due to consistent, moderate precipitation.
Answer: False
Explanation: Semi-arid climates typically support short, thorny, or scrubby vegetation like grasses or shrubs, as limited precipitation generally prevents forest growth.
Semi-arid climates receive precipitation below potential evapotranspiration, but not as low as a desert climate.
Answer: True
Explanation: A semi-arid climate is defined by precipitation levels that are below potential evapotranspiration, yet higher than those found in true desert climates.

To calculate the precipitation threshold for a semi-arid climate, the average annual temperature in degrees Celsius is first multiplied by 10.
Answer: False
Explanation: The initial step in calculating the Köppen precipitation threshold involves multiplying the average annual temperature in degrees Celsius by 20, not 10.
If less than 30% of the total precipitation in a region falls in the summer half of the year, 140 is added to the initial temperature-based calculation for the Köppen precipitation threshold.

The Köppen classification system uses the designations BSh and BSk for humid climates.
Answer: False
Explanation: The Köppen classification system uses BSh and BSk to designate steppe climates, which are intermediate between desert and more humid climates, not humid climates themselves.
How does the Köppen climate classification categorize steppe climates (BSh and BSk)?
Answer: As intermediate types between desert climates (BW) and more humid climates (A, C, D).

Answer: 280
Explanation: If at least 70% of the total precipitation occurs in the summer half of the year, 280 is added to the initial temperature-based calculation for the Köppen precipitation threshold.
What is the precipitation criterion for an area to be classified as a 'BS' (steppe, semi-desert, or semi-arid) climate?
Answer: Annual precipitation is less than the calculated threshold but more than half of that threshold.
