Answer:
The time span between 1680 and 1766 (lines 1 and 2) is 86 years: 1766 − 1680 = 86 years. During this time, the falls receded an average of 5.8 feet per year: 500 feet ÷ 86 years ≈ 5.8 feet per year.
The time span between 1856 and 1876 (lines 3 and 4) is 20 years: 1876 − 1856 = 20 years. During this time, the falls receded an average of 25 feet per year: 500 feet ÷ 20 years = 25 feet per year.

Answer:
1. Most volcanic islands originate from passive lava flows on the seafloor.
2. These passive flows harden into rock and build up the height of the underwater mountain over millions of years.
3. In addition to magma supply, plate tectonics play a large part in determining which submarine volcanoes will eventually form islands.
4. This volcano, West Mata, erupted in 2009 about 1,219 meters (4,000 feet) beneath the surface of the Pacific Ocean, between Fiji, Tonga, and Samoa.
5. The orange glow of magma is visible beneath the plume of volcanic gases (mostly yellowish sulfur) emitted by West Mata.

Answer:
Doldrums
Explanation:
The trade winds converge in the region of the ITCZ, producing convectional storms that produce some of the world's heaviest precipitation regions. The ITCZ moves north and south of the equator depending on the season and solar energy received
