What happens when the Earth is in its perihelion on January 1 or 2?
A. It becomes hotter on Earth.
B. It becomes colder on Earth.
C. It moves faster.
D. It moves slower.
once is enough, please.
moves faster at perihelion, regardless of the date
review Kepler's Laws
Oh, sorry.
But the earth also moves faster during perihelion?
I dunno which is which but thanks
becomes colder*
Quoted "It might seem logical to think that temperatures would rise when Earth is closest to the sun. In reality, Earth is at its coolest at perihelion! That's because rocks heat up much more quickly than water. Most of the landmass on Earth is in the Northern Hemisphere, and most of the Southern Hemisphere is ocean."
The Earth's perihelion refers to the point in its elliptical orbit around the Sun where it is closest to the Sun. This occurs around January 1 or 2. To determine what happens during this time, we need to consider the effects of this proximity.
A. It becomes hotter on Earth: When the Earth is in its perihelion, it does not directly cause a change in the Earth's temperature. The Earth's axial tilt is primarily responsible for the seasons, not its distance from the Sun.
B. It becomes colder on Earth: Likewise, being in perihelion does not directly cause a drop in temperature on Earth. The local climate is determined by various factors such as atmospheric conditions, ocean currents, and land properties.
C. It moves faster: This statement is true. According to Kepler's second law of planetary motion, a planet moves faster when it is closer to the Sun in its elliptical orbit. Therefore, when the Earth is in perihelion, it travels at a higher speed.
D. It moves slower: This statement is incorrect. As mentioned earlier, the Earth moves faster in its orbit when it is closer to the Sun, so it actually moves slower during other parts of its orbit.
So, the correct answer is C. It moves faster.
