Answer:
A) its elliptical orbit and tilt on its axis
Explanation:
Earth revolves around the sun in an elliptical path. Its axis is tilted to about 23.5° from the vertical.
These two factors determine the global climate on the Earth.
Due to elliptical orbit, the earth is sometimes closer to sun than the rest of the time. When it is closer the global temperature rises by 5 degrees. Due to the tilt of the Earth, seasons occur. The hemisphere which points towards the sun has summers where as which points away has winters.
Thus, the long-term climate change is effected by elliptical orbit and tilt of the axis.
Answer:
Option (A)
Explanation:
The type of season and climate that earth experiences at different places are due to the earth's tilt and because of the earth's elliptical orbit. During its motion along the elliptical path, the earth moves from one place to another, as a result of which the distance from the sun increases and decreases at various location. This is one of the factors why one experiences a different type of seasons. The earth is tilted at an angle of 23.5°, and the northern hemisphere experiences summer when the earth's tilt is towards the sun, and the opposite side experiences winter.
When this tilt of the earth will change along with the change in its orbital path, then there will be simultaneous changes in the climate and seasons, which could lead to long term change in the earth's climate.
Thus, the correct answer is option (A).
