What single feature is primarily responsible for the variation of climate in different parts of the world?
astraxan [27]

angle of incoming sunlight

Explanation:

The single feature that primarily determines the variation in climate in different parts of the world is the angle of incoming sunlight.

  • Climate is simply an extended study of weather over a long period of time.
  • The elements of weather like temperature, pressure, rainfall all conditions climate.
  • The angle of incoming sunlight is by far the most important factor that determines climatic patterns on the earth.
  • Around the equator, the sun is overhead and these regions are usually hot driving a wide range of weather phenomenon.
  • The polar and temperate regions receive diffused sunlight because the sun is at an angle there.

Why doesn't our hands swell up due to osmosis , when we keep it in water for a long time ??
DerKrebs [107]
A cell wall is a permeable layer found in plant cells which acts as a membrane through which water molecules can pass through while animal cells do not have cell walls.. they just have a cell membrane which is selectively permeable to some chemicals or substances.. water does not move from the region of higher to lower concentration in animal cells

In short, plant cells have cell walls that allow osmosis while animal cells do not have cell walls for osmosis to take place

hope it helps you :)

Instead in our hands... something else happens rills or groove shaped lines are formed in our fingers.. it is an adaptation for our body to provide for some friction in water...
