What causes seasons?

What causes Earth’s seasons? Earth’s elliptical orbit and varying speed of revolution Variation in the amount of energy given off by the sun Earth’s greater distance from the sun during winter than summer Inclination of Earth's axis upon rotation and its revolution around the sun

Earth's seasons are caused byMultiple choice question.ocean and wind currents.the rotation of Earth on its axis.the tilt of the Earth on its axis.the distance of Earth from the sun.

Summarize what seasons are used to describe

What are the reasons why the Earth has seasons?The Earth is not tilted and therefore doesn't have seasons.1) Earth is tilted 23.5 degrees2) Earth Revolves around the sun3) Parallelism of Earths axis ( Earths North Pole always points towards Polaris)

A season is a subdivision of the year, marked by changes in weather, ecology, and hours of daylight. Seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earth's axis relative to the plane of revolution. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface. These variations may cause animals to go into hibernation or to migrate, and plants to be dormant. It is scientifically fascinating how bears and other animals instinctively know when to hibernate. During May, June and July, the northern hemisphere is exposed to more direct sunlight because the hemisphere faces the sun. The same is true of the southern hemisphere in November, December and January. It is the tilt of the Earth that causes the Sun to be higher in the sky during the summer months which increases the solar flux.(Adapted from Wikipedia)Which sentence is unnecessary and could be eliminated without disturbing the flow and information of the paragraph?ResponsesA These variations may cause animals to go into hibernation or to migrate, and plants to be dormant.These variations may cause animals to go into hibernation or to migrate, and plants to be dormant.B It is scientifically fascinating how bears and other animals instinctively know when to hibernate.It is scientifically fascinating how bears and other animals instinctively know when to hibernate.C It is the tilt of the Earth that causes the Sun to be higher in the sky during the summer months which increases the solar flux.It is the tilt of the Earth that causes the Sun to be higher in the sky during the summer months which increases the solar flux.D Seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earth's axis relative to the plane of revolution.
