What the affects the angle at which the suns rays hit earth?
The light from the sun travels in a straight line, and we can assume the light rays to be parellel. The angle of incidence on the earths rounded surface depends on where you are on the earth and what time it is. Mid-day on the equator and the rays would hit the ground straight on. Further to the north or south, or later/earlier in the day and the light rays would hit at more of angle. The rays would also have to penitrate more of the earths atmosphere as the angle increases, which takes more `strength` out of the sun.
Earths rotational axis is oriented perpendicular to the suns rays on the first day of?
The plane upon which the Earth travels round the Sun is called the ecliptic. It is only when two bodies are on this plane, and in line with the Sun, that an eclipse is observed. Hence the name ecliptic. The Earth's spin axis is always oriented about 23.4 degrees from the ecliptic plane. The Earth's spin axis is never perpendicular to the Sun's rays. You may be referring to the Sun being directly overhead at the Equator twice per year.
At 11 am on January 13 If the length of the shadow is 2 m and 44 cm what is the Suns zenith angle?
The angle of the sun can be worked out through trigonometry, but first you will need the height of the object that is causing the shadow, since a taller object will make a longer shadow. Tan a = H/2.44 Where a is the angle and H is the height of the object. And the date is not relevant.
What are the cooler areas on the suns surface?
sunspots
What is the suns rotational period?
25 days
Does The angle that the Suns rays strike a region of Earth determine the amount of heat transferred.?
true :)
When do the Suns Ray strike latitude 23.5s at an angle of 90 degrees?
June 21
What happens to temperature as the angle at which the suns rays strike the earths surface decreases?
As the angle at which the sun's rays strike the Earth's surface decreases, the energy from the sun is spread over a larger area, leading to lower intensity of heating. This results in a decrease in temperature as less heat is absorbed by the surface.
When the suns rays strike earth's surface energy is?
Absorbed
How do the suns rays strike earth in the polar zones?
Obliquely
Do the suns rays that are at an angle produce more heat?
no
What is the tilt of the earth for winter?
In summer the suns rays travel directly to the surface at a steep angle, so are still warm. In winter the rays strike at a shallower angle, and cool down rapidly as they travel a longer distance through the atmosphere before reaching the surface.
When do the suns most direct rays strike in the western hemisphere?
During the daytime.
When the suns rays strike the earths surface energy is absorbed or reflected?
absorbed
What angle will the suns rays most directly hit the earth?
the equater A+ 90 degrees
How are the suns rays different at the equator compared to the poles?
Only in the angle of incidence.
The tilt of earth changes how the suns rays strike the?
The tilt of the earth changes how the sun stikes
