Final answer:
The question touches on the concept of continental drift, a key topic in Geography, outlining how continents are separated by oceans due to tectonic plate movements. Examples such as clathrates and coral reefs are important components of marine ecosystems that contribute to ecosystem services.
Step-by-step explanation:
The student's question appears to be asking about the concept of continental drift, which is a key topic in both Geography and earth science. This scientific theory explains how continents have moved over geological time to their current positions on the Earth. The process is driven by tectonic plate movements and can result in the continents being separated by oceans.
Clathrates, which are frozen chunks of ice and methane found at the bottom of the ocean, and coral reefs, ocean ridges formed by marine invertebrates living in warm, shallow waters within the photic zone, are important parts of the marine ecosystem. These, along with other ecological systems such as mangroves and estuaries, contribute to the ecosystem services that provide benefits to human society.
