what causes summer and winter?

Answer 1

(m)

The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 22.5 degrees relative to the "ecliptic plane" (the imaginary surface formed by it's almost-cicular path around the sun). The tilt toward the sun is maximized during Northern Hemisphere summer in late June (the "summer solstice"). At this time, the amount of sunlight reaching the Northern Hemisphere is at a maximum. In late December, on the date of the "winter solstice", the tilt away from the sun is maximized, leading to a minimum of sunlight reaching the Northern Hemisphere. The seasons, of course, are reversed in the Southern Hemisphere.

During the winter, cold air masses build up over North America, Europe, and Asia, due to the low intensity of sunlight. The oceanic air masses are much less affected by the seasons because circulations in the upper ocean replenish warm surface water if it has been cooled. The strong temperature contrast between the cold air masses over land and the relatively warmer air masses over the ocean lead to extratropical (non-tropical) cyclone formation (low pressure). These storms are thus much more frequent and intense in the winter than in the summer

Interesting facts:
The sun is actually closest to the Earth during Northern Hemisphere winter (not summer). Thus, the amount of sunlight averaged over the whole Earth, is about 7% more intense in the winter than the summer.

Answer 2

The tilt of the Earth's axis, and the high latitudes of the places north and south of the Equator (tropical region without 4 seasons)

The sun's rays take a longer time and longer distance to travel through the higher atmosphere at the higher latitudes (due to the curvature of earth's surface), and when the Earth's tilted away from the sun. Thus the colder weather..and winter.

Answer 3

The seasons result from the Earth's axis being tilted to its orbital plane; it deviates by an angle of approximately 23.5 degrees of arc. Thus, at any given time during the summer or winter, one part of the planet is more directly exposed to the rays of the Sun.This exposure alternates as the Earth revolves in its orbit. At any given time, regardless of season, the northern and southern hemispheres experience opposite seasons and Effect of sun angle on climate.

Answer 4

the rotation of earth causes summer and winter

Answer 5

The earth is in an egg shaped orbit around the sun. when were closest it's summer & the farthest point is winter.

Answer 6

the lean of the earth motives the seasons. even nevertheless, that's not completely because of the dimensions of the day, as proposed by way of the 1st answerer. The substitute in warmth is extra straight away because of the perspective of occurrence of the sunlight on the outdoors. while the earth is tilted in direction of the sunlight (summer time), the sunlight falls on earth straight away, inflicting its warmth to be extra targeted, as a effect extra warmth impinging on earth consistent with unit area. while the earth is tilted far flung from the sunlight (iciness), the equivalent bypass area of photograph voltaic power is unfold over an even bigger area of the earth's floor, so there is far less warmth consistent with unit area.

Answer 7

by the way the Earth goes around the Sun.

Answer 8

earth's revolution round the sun.

Answer 9

life .....
