12. One type of wave on the ocean is generated by wind. The distance wind is able to blow in a straight line is called the fetch. The longer the fetch, the larger the wave can grow. Study the globe or world map. Does the Pacific, Atlantic, Indian or Arctic offer the longest fetch

Pacific ocean offers the longest fetch.

Explanation:

An ocean is said to be a large body of water separating the continents.  The Fetch of an ocean surface is where the wind blows in a constant direction, which further generates waves. It is also the horizontal distance over which wave-generating winds blow. Part of the factors affecting the ocean fetch is the wave and the larger the ocean, the larger the wave, thus increasing the ocean's Fetch. The pacific ocean has the largest Fetch from the given option because it is the largest and deepest of all the oceans on the continent.
