Question

Which process causes the formation of underground tunnels and caverns? (3 points) a Melting of glaciers b Exposure of coral reefs c Overflowing of rivers and lakes d Dissolution of limestone bedrock

Answer 1

Answer:

Its D.

Explanation:

Answer 2

Answer:

Solution caves are formed in carbonate and sulfate rocks such as limestone, dolomite, marble, and gypsum by the action of slowly moving ground water that dissolves the rock to form tunnels, irregular passages, and even large caverns along joints and bedding planes.

Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons. ... Alarmingly, if all the ice on Greenland melted, it would raise global sea levels by 20 feet.

Long periods of exceptionally low tides leave shallow water coral heads exposed, damaging reefs. The amount of damage depends on the time of day and the weather conditions. Corals exposed during daylight hours are subjected to the most ultraviolet radiation, which can overheat and dry out the coral's tissues.

A flood occurs when a river or stream overflows its banks. Seasonal floods are the norm in many rivers, for example when spring rains or snowmelt increase the flow.

Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions.
