Steppe climates (BS) are considered:
Answer:
Semi-arid
Steppe climates are transition zones between deserts and humid climates. They are semi-arid, receiving enough rain to support grass but generally not forests.
32
Which climate zone typically experiences the smallest annual temperature range?
Answer:
Tropical Rainforest
Tropical Rainforests sit near the equator where day length and sun angle vary little throughout the year, leading to very stable temperatures with little seasonal variation.
33
Climate differs from weather in that climate is:
Answer:
The long-term average of weather patterns (usually 30+ years)
Weather is the atmospheric condition over a short period (hours/days), while climate is the statistical average of weather events over a long period, typically 30 years.
34
The Atacama Desert is dry primarily due to:
Answer:
The Cold Peru (Humboldt) Current
The cold Peru Current cools the air above it, preventing it from holding moisture and creating a stable atmosphere that suppresses rainfall, making the Atacama one of the driest places on Earth.
35
Which of the following is NOT a characteristic of a Highland (H) climate?
Answer:
Uniform conditions over large areas
Highland climates are defined by their variability. Conditions change rapidly over short distances due to changes in elevation, slope, and exposure, rather than being uniform.
36
The Humid Subtropical climate (Cfa) is typically found on the:
Answer:
East coast of continents between 20-40° latitude
Humid Subtropical climates (like the SE USA and SE China) are found on the eastern sides of continents, influenced by warm ocean currents and unstable maritime tropical air.
37
Which symbol in the Köppen system indicates a climate with a 'Dry Winter'?
Answer:
w
In the Köppen system, the second lowercase letter describes precipitation patterns: 'w' stands for winter dry season, 's' for summer dry season, and 'f' for no dry season (feucht).
38
The 'Taiga' or Boreal Forest is found in which climate zone?
Answer:
Subarctic
The Subarctic climate (Dfc, Dwc), found only in the Northern Hemisphere, creates the conditions for the Taiga, the world's largest land biome composed mainly of coniferous forests.
39
Which ocean current keeps the climate of Western Europe significantly warmer than other regions at the same latitude?
Answer:
North Atlantic Drift (Gulf Stream)
[attachment_2](attachment) The Gulf Stream (specifically its extension, the North Atlantic Drift) transports warm tropical water to the North Atlantic, warming the air that blows over Western Europe.
40
Permafrost is a defining characteristic of which climate zone?
Answer:
Tundra
The Tundra climate (ET) is characterized by at least one month with an average temperature above 0°C but no month above 10°C, resulting in permanently frozen subsoil known as permafrost.
