If M is the Moon's sidereal orbital period (in days), then the Moon revolves around the Earth at a rate of 360 / M Â° per day. So in a time interval t days, the Moon revolves around the Earth t Ã 360 / M Â°. If Y is the Earth's sidereal orbital period in days, then the Earth revolves around the Sun at a rate of 360 / Y Â° per day and so in t days the Earth revolves around the Sun t Ã 360 / Y Â°.
Mangroves are a group of trees and shrubs that live in the coastal intertidal zone. Mangrove forest in Loxahatchee, Florida. There are about 80 different species of mangrove trees. All of these trees grow in areas with low-oxygen soil, where slow-moving waters allow fine sediments to accumulate.
Mangrove forests grow on tropical coasts with soft soils and are flooded twice daily by the tide. They are important nursery areas for many species of fish. Mangroves and coral reefs have a symbiotic relationship â the reef protects the coast where the mangroves grow from being eroded by the sea, and the forest traps sediment washed from the land that would otherwise smother the reef.
