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.
Mangroves live life on the edge. With one foot on land and one in the sea, these botanical amphibians occupy a zone of desiccating heat, choking mud, and salt levels that would kill an ordinary plant within hours. Yet the forests mangroves form are among the most productive and biologically complex ecosystems on Earth.
