Average global temperatures are higher when the earths orbit is more elliptical and cooler when the orbit is more circular how c
svlad2 [7]

The obliquity (axial tilt), precession (wobble), and the eccentricity (how close to being circular) of the Earth’s orbit, comprise the Milankovitch cycle. These three factors affect the amount of heat energy from the sun (solar heat) directed to Earth, influencing climactic changes and patterns.


The tilt of the axis mainly affects the amount of solar heat each hemisphere receives. The greater the tilt, the more solar energy is directed at the northern hemisphere. Along with precession, they also affect the length of days and nights experienced by certain parts of the Earth.


The eccentricity of the orbit affects the distance of the Earth to the Sun during its revolution in orbit. The orbit is an elliptical path followed by the Earth, with the Sun not exactly at the center. Thus, there is a time when the Earth is closest to the Sun (perihelion) and this allows the Earth to experience radiation the most. On the other hand, there is also a time when Earth is farthest to the Sun (aphelion). This difference in distance creates a heat exposure retained by the Earth. From the time of perihelion it absorbs so much solar energy and is gradually expended revolving but at the same time still absorbing solar heat – hotter global temperature .


If the orbit was more circular, the distance of the Earth to the Sun will always be the same at any point in the orbit. Thus, allowing equal exposure to the Earth at all times. There will be no point in time in which the Earth will absorb so much heat. This will cause a cooler global temperature compared to the elliptical orbit.

Why was carbon-14 perfect for determining the dates that organisms died?
Alex777 [14]

Answer: B.

Explanation:

cant be 'A' cause carbon 14 is found in any living organism and mammals are not the only living organism on this planet

cant be 'C' cause ancient plants still replenish carbon 14 molecules and it'd be impossible to now its age when its still alive

couldnt be 'D' cause yeah while alive organisms do absorb carbon 14 that still defeats the purpose of dating with the carbon 14 method cause its still also taking in carbon dioxide, so the carbon-14 molecules will just keep filling until the organism dies. the whole point of dating with carbon 14 is to measure its deplenish (dying) not continual replenish (living)

dont know if that makes any sense to you but yeah 'B' is the answer, if it isnt im stoopid but im not
