Answer:
Coastal development causes loss of semi-natural and natural land, destruction and fragmentation of coastal habitats.
The Jupiter-like masses or hot Jupiters are gas giant exoplanets that are found outside the solar system.
Formerly, scientists used to rely on planetary formation theories which stated that the hot Jupiters are only found at a very large distance from the stars. Later, the discovery of hot-Jupiters came as a surprise to astronomers because they are found so close to their stars.
Hydrothermal Vents occur along divergent plate boundaries on the ocean floor. Hydrothermal vent systems give off plumes of hot, mineral-laden water with temperatures as high as 350 degrees Celcius. The water is ejected through a spout known as black smokers. Metal-rich minerals precipitate out of the circling sea water and forms ores of copper, zinc and iron.
