Question

The cycle of the season is caused by______
A) The varying distance between earth and sun
B) Spherical shape of earth
C) The tilt of earth’s axis
D) The presence of plants and animals

Answer 1

Hint:Each season has essential characteristics, at the same time varying from one to another, prompting the same all around the world. Planet still spins at an angle all around the sun in a way that the whole earth will experience various seasons.

Complete answer:
The tilted axis of the Earth triggers the seasons. Throughout the year, various areas of the Planet receive the most direct rays from the Sun. So it's summer in the Northern Hemisphere as the North Pole tilts towards the Sun. And it is winter in the Northern Hemisphere as the South Pole tilts towards the Sun.
Option A), is incorrect. In January, as the Earth is nearest to the Sun, the Sun generally receives more intense light than when it is further away at the beginning of July. So the Earth-Sun gap increases our temperature when we're closer to the Sun, but the seasons are still influenced by axial tilt.
Option B) is incorrect. The Earth's Spherical Form. The surface gets much more intense sunlight (heat) at the equator than at the poles since the Earth is a sphere. The Sun passes directly overhead at noon on the equator during the equinox (the time of year when the sum of daytime and nighttime are roughly equal).
Option C) is the correct answer. What makes us seasons is this tilt. The Earth's axis still points in the same direction, so each hemisphere gets different amounts of sunlight as the planet works its way around the sun.
Option D) is the incorrect answer. The presence of animals and plants are important for earth’s ecological environment.

Hence the correct answer is option C.

Note: Global warming is the long-term warming observed since the pre-industrial era (between 1850 and 1900) of the Earth's climate system due to human activities, mainly fossil fuel burning, which raises the amount of heat-trapping greenhouse gases in the atmosphere of the Earth.
Many forms of disasters, including hurricanes, heat waves, floods and droughts, are getting worse with higher temperatures.
