I have a question about the sun....?

Question

Hi, I was washing the dishes this morning and thought of this... why is the sun cold in the morning but hot in the afternoon (i mean like weak and strong)? Does it get closer to the earth in the afternoon or what??

Answer 1

  You are separated by more atmosphere in the morning and evening than at noon when the sun is straight up.

Answer 2

good question. it's cooler in the morning because the sun isn't exposed as  long  when rises compared to when it is fully risen. for example, think a stove top. when you turn on the gas or electricity, the coils are cooler than when you let it sit on that set dial for a period of time.  why? because the molecules on the coil have only begin to vibrate (warmer) when you initially turn on the stove and eventually reaches a max temperature as the maximum amount of heat inputted is reached (equivalent to mid-day).

a second factor is the amount of sun exposure at the specific face you are at.  as you know, the earth rotates and certain sides of the earth face the sun at a given time.  at sun rise, there could be only 30 percent of the sun visible on the face of the earth you are living at thus not as many rays are pointed and heating the air molecules.  an example would be a fan.  if you allow the fan to blow air but cover half of the circumference then a smaller area of air molecules will be blown.

Answer 3

The earth rotates every day! It's hottest around noon because the sun is directly over your position on the planet, and has less atmosphere to go through as opposed to the angles in the morning and evening. The heat goes to you more directly, so more intensely.  The sun isn't moving...you are.

Answer 4

my best guess is that in the morning you ain't facing the sun like you are in the afternoon

Answer 5

Like all of us it takes a while to get working at full strength.

In the early morning its not operating at full steam but by the afternoon its firing on all cylinders so it feels hotter.  

Answer 6

The sun takes time to warm up, just like the engine of your car.  It is cold at first but then warms up.  At the end of the day it turns off and then slowly cools off.

An interesting aspect of this is that because the earth is a sphere, while you get a nice warm sun during the day, people on the other side of the earth are in constant shadow and never get to see the sun.

Answer 7

it always hot it's the sun. it just  take time for it to heat up the earth

Answer 8

something related to wavelengths

varies with the position on earth

Answer 9

In the morning, the sun is close to the horizon and the light has to travel through a lot of atmosphere before it gets to you. The heat is absorbed by all the air along the way and only some of it reaches you. In the afternoon, the sun is high in the sky, so the light only travels through a small amount of atmosphere to reach you.

Answer 10

Because during the morning the sun's rays are hitting the Earth at an angle so it is spread out and not as powerful. During midday, the rays are more direct and more intense.

Answer 11

The suns temperature doesn't change. The earth rotates. Thats why we have days. In a 24 hour span the earth will rotate once. When it rotates half of the world is facing the sun and half isn't. Naturally, the side facing the sun will be hotter and as the Earth rotates the area of the Earth facing the sun will change. Think of it like this: spin a basketball on your finger. Your face is the sun. Whenever you see the logo of the basketball its daytime in that area. when you don't its night time in that area. its hot in the day, cold in the night. i probably could have explained it better. i'm sorry if it doesn't make sense.  

Answer 12

What you said is correct...you got ur answer logically...

Answer 13

Common sense really it take a while to heat the area in much the same way as you may heat a cold room.

However the sun is stronger when it is closer to the earth especially if you are living close to the equator, then of course we have global warming.

Answer 14

The higher the sun is in the sky, the more energy per square foot strikes the surface of the earth (or you, if you are in the sun.) Precisely speaking, the amount of solar energy per unit area is proportional to sin^2 a, where a is the altitude of the sun over the horizon.

Answer 15

no doubt, this is elementary education. in the morning the sun isnt straight above u like it is midday, so the suns uva uvb and gamma rays are on an angle and hence, weaker.

Answer 16

Good question. Many people don't know the answer to it.

The sun itself doesn't change temperature. The Earth's rotation causes it to change position relative to the Earth's atmosphere.

The main reason for the temperature change is because of the horizon, and the atmosphere. Because of the Earth's curvature, the atmosphere curves too. When the sun is at the horizon, it is passing through more atmosphere than it is when its straight above us. When it passes through the atmosphere, the sun's light gets scrabbled, and not as many rays are directed towards you, thus making a colder temperature.

The temperature is usually higher when the sun sets than when the sun rises. Again, this is because of the atmosphere. Earth's atmosphere makes Earth capture and reflect a lot of the sun's heat back onto the Earth's surface. This is why the Earth's temperature doesn't drop to low temperatures at night. This is because of Earth trapping a lot of the heat. When the sun sets, the sun has been shining on the Earth all day. But when the sun rises, it has been night, and a lot of the sun's heat escapes.

The sun doesn't get any closer to the Earth at any noticeable distance when it rises and sets.

Answer 17

If you take a flashlight into a large dark room and point it toward the floor on the other side of the room the beam is considerably spread out and relatively weak.  If you now shine it directly down the light is far more concentrated.  The morning angle spreads out the sun's light on any flat ground while the light is concentrate when the sun is directly overhead.  Also, in the morning it takes time to remove the night chill and the suns light seems cooler.  Also, in the morning the light must travel a longer path through the atmosphere (than at high noon) and much sun light is lost due to greater diffusion.  It is possible to look at the sunrise or sunset but not at the sun directly overhead.

Answer 18

Its not fully out in the morning.

Answer 19

Well when you wash dishes, better think about dishes otherwise they can remain unclean!!!!!!

And yes, i think the sun is closer to us in afternoon, and thats why its hot.

Answer 20

because the longer its up there the more heat you get. cooler when there is no sun.

Answer 21

It all has to do with the cycles of the sun. As you know, it gets dark at night and light during the daytime. This is because the sun is at a certain angle towards Earth and the spot it's closest to is where it's the warmest and brightest. In the morning, the sun has not fully reached the area of the world you live in and is still in the process of moving (although it never stops). This explains the cooler temperature in the morning because the sun can not fully concentrate its heat there when it is not completely there. In the afternoon, the sun is much closer to the area of the world you live in and therefore, it is much hotter and brighter.

Answer 22

duh!!! cuz its on the sides of the earth not on the top...in the morning, half of the sun's light is reflected by the atmosphere... as for in the afternoon the sun's light is Vertical on earth so the light can't be reflected as much as it is in the morning.

can u answer mine?

Answer 23

The sun feels cooler in the morning because it hasn't warmed up the cold night air yet. Also, the suns rays have to cut through the atmosphere at an angle so in effect, it IS further away and being filtered through more air than when it is right above you.

Answer 24

the shade is cool right
