Clearcutting:Method of timber harvesting in which all trees in a forested area are removed in a single cutting. Compare, seed-tree cutting, selective cutting, shelterwood cutting, strip cutting.
Shelterwood cutting:Removal of mature, marketable trees in an area in a series of partial cuttings to allow regeneration of a new stand under the partial shade of older trees, which are later removed. Typically, this is done by making two or three cuts over a decade. Compare clear-cutting, seed-tree cutting, selective cutting, strip cutting.
Seed-tree cutting:Removal of nearly all trees on a site in one cutting, with a few seed-producing trees left uniformly distributed to regenerate the forest. Compare clear-cutting, selective cutting, shelterwood cutting, strip cutting.

Ans.

Shelter-wood cutting is defined as a method of forest cutting that leads to establishment of a new seedling generation of a group a species or a particular species without planting. It is applied in those forests, which are considered as mature, generally after thinning.

Clear-cutting is a method of forest cutting, in which nearly all or most of the trees, found in an area are uniformly cut down. The principal objective behind clear-cutting is to regenerate a forest with healthier plants, instead of getting timbers.

Seed-tree cutting is defined as a method that uses removal of most of the trees from a region and leaving some trees behind, which can produce seed for the regeneration of that forest. It is used for the regeneration of tree that grow well in the presence of direct sunlight, such as pine trees.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
