Tropical cyclones impact the environment, society and the economy in negative ways, according to figures there are annual losses in the US estimated at US$5 to 10 billion.
<h3 /><h3>Formation of tropical cyclones</h3>
They correspond to low pressure centers with high humidity and high temperature that form around the tropics, generating torrential storms and high-speed winds.
Therefore, with winds that can reach up to 250 km/h, tropical cyclones can cause destruction, landslides and floods, putting the lives of thousands of people at risk.

Answer:
Corals reef is a underwater ecosystem that builds on limestone beds, CaCo3
Explanation:
- They have exoskeletons made up of limestones and its possible that the corals might have moved offshore with changes in the sea levels as, he finds an abundance of large clam fossils, that produce within the interlocking of limestone section.
- Since the clam is made up primarily of coral fragments its possible that the corals might have buried under the landmass when the upliftment was completed.
- The skeletal remains of the coral polyps that are now stratified in the rocks are suggestive of reef formation around the landmass earlier period and these were mostly found in tropical oceans.
- Thus as he moves away and sees limestones with shales, which has clam fossils he had seen previously.
It is the source of the nation's petroleum deposits.
