The coconut tree grows from a single seed, which is an entire coconut, taking between six and 10 years to bear fruit, and living between 60 and 80 years. Each coconut takes a year to develop from a flower into a fruit. These fruits bear thick, tough husks and achieve a very wide distribution by dropping into the oceans where currents carry them, sometimes for thousands of miles.Know More
Coconuts are an important fruit in many parts of the world, though humans are one of the few species that can actually make use of them. The heavy fruits are known as drupes, which are a group of fruits that includes species such as plums and peaches. Drupes have a hard seed pod surrounded by a mass of softer tissue. The fruit of a coconut is extremely fibrous and very tough. Its structure protects it from hungry animals as well as protects the embryo on long ocean journeys, keeping out salt water and preserving the seed for up to three months at sea.
Research suggests that coconuts first appeared near the Indian Ocean, but because of their remarkable dispersal abilities reached South America before human travel across the oceans was even possible.Learn more about Earth Science
The water cycle, also known as the hydrologic cycle, describes the process of how water moves through Earth's environment. In general, water evaporates from oceans, then it condenses in the atmosphere as water vapor cools. When enough water gathers in clouds, it precipitates back to the Earth's surface as rain, hail, snow or sleet.Full Answer >
The hydrologic cycle refers to the continuous movement of all water contained on the Earth. This includes water which exists in the form of liquid, ice and vapor found on, above and below the surface of the Earth.Full Answer >
Percolation is part of the water cycle that occurs after precipitation and before storage during which water filters down through aerated soil due to gravity. After percolation, water is stored in groundwater reservoirs until it reaches a point where sunlight warms it and the water evaporates. Much like a coffeemaker percolates water from top to bottom, water percolates down through soil until it reaches the water table.Full Answer >
In the nitrogen cycle, legumes form a symbiotic relationship with certain types of bacteria that are involved in a process known as "nitrogen fixation." The legumes provide the microorganisms with the required energy to initiate the process, while the bacteria fixes captured nitrogen from the air into a usable form, which is absorbed by the legumes for sustenance.Full Answer >
