Question

which of the following best describes how coral reefs influence the geosphere over time? (1 point) they dissolve completely without leaving any trace they form limestone structures that change coastal landscapes they turn into mountains through plate tectonics they form clouds that block sunlight

Explanation:

Coral reefs are made of calcium carbonate from coral skeletons. Over long periods, they accumulate and form limestone, which alters coastal landforms (part of the geosphere). The other options are incorrect: corals do not dissolve without a trace, they do not directly become mountains, and cloud formation is unrelated to their geospheric influence.

Answer:

They form limestone structures that change coastal landscapes
