When the Sun's rays strike earths surface energy is what?
Absorbed
What is the definition for direct rays of sunlight?
a direct ray is where the sun light hits the earth at a 90 degree angle so the angle of sunlight is perpendicular to the earths surface
Do x-rays have more energy than gamma rays?
No, gamma rays have the highest energy of all the waves in the Electromagnetic Spectrum.
If a dark field condenser causes all light rays to bypass the objective where does the light come from that makes an object visible in a dark field?
Oblique rays that strike the object. Oblique rays strike the object being viewed, illuminating the object and reflect light rays up through the objective.
How is energy tranferred to the air near the surface of the esrth?
A mix of conduction and convection. (We're talking heat energy from solar radiation here.)
When the Sun's rays strike earths surface energy is what?
Absorbed
When the suns rays strike the earths surface energy is absorbed or reflected?
absorbed
How does the angle of which the suns rays strike the earth affect the temp at the earths surface?
blah
When the suns rays strike earth's surface energy is?
Absorbed
When the sun rays strike the earth's surface energy is?
Absorbed
What is the colder at high latitudes because the sun's rays strike earths surface at a angle there?
Oblique
Is energy absorbed or reflected when the sun's rays strike the earth's surface?
Energy is being absorbed AND being reflected when the sun's ray strike the Earth's surface.
What happens to temperature as the angle at which the sun's rays strike the earths surface decreases?
Usually, as the angle of incidence of the sun's rays decrease (i.e. when the sun is nearer to the horizon than to the zenith) the temperature decreases.
What is the different between oblique rays and vertical rays?
Either the answer will be that they contain more solar energy, it strike's the earth at an angle greater than 90 degrees, or it could be that they spread energy over a larger surface area.
What layer of the atmosphere protects the earths surface from UV rays?
The Ozone layer.
What are the two sources of energy in the earths system?
The sun's rays and wind.
How are oblique rays different from vertical rays?
Obviously the angle of incidence is different. The oblique rays spread their energy over a larger area of the surface than vertical (also called perpendicular or normal rays)
