Why is a sidereal day shorter than a solar day on earth?
Nadusha1986 [10]
The Sidereal Day is 4 minutes shorter than the Mean Solar Day, because the rotation of the Earth on its axis, and the orbiting of the Earth around the Sun, are both counterclockwise, as viewed from above (or north of) the Ecliptic Plane. See planetary retrograde motion for an example of the opposite situation.

The reason that the Solar Day varies around the Mean Solar Day is that the Earth moves at different speeds through its orbit around the Sun. This is in keeping with Kepler's Second Law of Planetary Motion.

Please note that the Mean Solar Day changes over a long period of time, due to the slowing of the rotation of the Earth due to tidal forces exerted on the Earth primarily by the Moon. For example, the Mean Solar Day was about 23 hours about 250 million years ago.

Explain how the edges and corridors can strongly influence landscape biodiversity
Dahasolnce [82]

Answer:

The edges or boundaries between the ecosystems and within it are the illustrating characteristics of landscapes. In a landscape, the biodiversity is affected by the composition of the landscape itself. When an area possesses boundaries or edges, which minimize the area of the habitat, it also starts to minimize the number of species, which can associate with the communities.  

The multiplication of edge species can exhibit both negative and positive influences on the biodiversity of a community. On the other hand, corridors refer to the region associated with the populations of wildlife distinguished by human activities like road construction. The prime objective of designing habitat corridors is to enhance biodiversity. The corridors that have been protracted to other habitat patches can reinstate a certain degree of space and at the same time reestablish certain chances for genetic diversity.
