Read the paragraph below and answer the following question: What effect do winds from the ocean have on land near the ocean?
The irregularity of land and water forms contributes to the variations in the earth's heating and cooling and the winds, which carry weather. Land near the ocean is warmed in winter and cooled in summer by winds from the ocean. The oceans, covering more than 70 percent of the earth's surface, heat and cool slowly. Land surfaces react quickly, absorbing and releasing heat. Warm or cold winds originating over the vast expanses of water are delayed and changed in character by mountain ranges as they blow over the land masses of the world.
This is a great example of a reading comprehension question. Your job is to find the information the question asks for within the reading sample.
One way to do this quickly is to scan, or read quickly, for "key words". In this question, try scanning for the phrase "land near the ocean". You'll see that it appears once, in the second sentence. You could also try scanning for "winds from the ocean", which would likewise lead you to the second sentence. The second sentence is "Land near the ocean is warmed in winter and cooled in summer by winds from the ocean".
Your teacher probably wants you to rephrase the answer, rather than just directly copy. You can do this by adding related information from elsewhere in the paragraph. In this case, I see in the last two sentences that oceans heat and cool slowly, while land surfaces react quickly. That information explains why ocean temperature moderates land temperature.
The beginning of an answer might be: Because oceans heat and cool slowly while land surfaces react to temperature changes quickly, ....
