Question

Quizplus · Accepted Answer

Marine sediments provide the longest record of climate change as they accumulate over long periods of time and are not subject to erosion or disturbance like tree rings or glaciers. They also contain important information about the chemistry of the ocean and the atmosphere, which can provide insight into past climate conditions. Corals can also provide a long record of climate change, but they are limited to the tropics and subtropics and may be affected by local environmental conditions.
