Annimal Behavior
Annimal behavior id dictated most of the time with the disire to get food, to avoid predators and to reproduce.
-
-
Behaviors change within generation , and can be affected by the change of environment over time, due to emigration or immigration or even natural disasters.

Behavioral Rythm
-
in navigation by some migrating species, it has a major role
-
The change in a population size: the change in a population size is equal to the rate of birth +thre rate of immigration,-the rate of Emigration, - the deaths.

the rotation of the earth is the principal cause of climate variation on earth,and then is a big factor influencing the direction of the wind.

At the Earth's poles, the air is at high pressure and low temperature; at the Equator, it is at low pressure but higher temperature. This, together with the spin of the Earth on its axis, creates a pattern of warm and cool winds around the globe.
An equinox is commonly regarded as the instant of time when the plane of Earth's equator passes through the center of the Sun. This occurs twice each year: .
We have seasons because the earth is tilted (wonky) as it makes its yearly journey around the sun. The Earth's axis is tilted at an angle of 23.5 degrees. This means that the Earth is always "pointing" to one side as it goes around the Sun.
There are several factors that influence the amount of sunshine received at various places on the earth. The major factor is that while the sun is overhead at the equator, it is at a rather slant angle at the poles. This effect can be demonstrated using a torch, which can be taken as the sun.
