How many of the pairs given above is/are correctly matched ?
This question asks us to identify how many pairs of world climate types and their characteristics are correctly matched. We need to analyze each given pair to determine its accuracy.
The 'Tropical wet and dry' climate, often referred to as a Savanna climate, is characterized by distinct seasons. A key feature is a pronounced dry season, which typically occurs during the cooler winter months when the sun's angle is lower. Therefore, this match is correct.
Steppe climates are known for their semi-arid conditions, receiving limited rainfall. They are found in the mid-latitudes, often forming transitional zones between deserts and more humid climates. The characteristic described, 'Mid-latitude semi-arid or dry', accurately represents this climate type. Thus, this match is correct.
Humid sub-tropical climates generally experience hot, humid summers and mild winters. While rainfall can vary, many subtypes (like the common Cfa Köppen classification) receive adequate precipitation throughout the year, meaning they don't have a distinct dry season. The summers are indeed warm. Therefore, this match is considered correct in a general sense.
The 'Marine west coast' climate is known for its moderate temperatures year-round, with mild summers and mild winters, influenced by proximity to oceans. It typically experiences consistent rainfall distribution throughout the year ('No dry season'). However, the summers are characteristically mild or cool, not 'severely cold'. Severely cold summers are not a feature of this climate. Hence, this match is incorrect.
Based on the analysis of each pair:
Counting the correctly matched pairs (I, II, and III), we find there are 3 correct matches.
