The zenith angle id the angle the sun makes with the ground it is used to calculate the incoming solar radiation. If the sun is directly overhead, the solar radiation has less distance to travel throught the atmosphere and it is less likely to get scattered and absorbed so more uv will reach the surface
In short the zenith angle is when the sun is at its highest in the sky
"Picture a mountain peak" is a good way to remember the definition for zenith.
The highest point. It is used especially about the position of the sun; when the sun is at its zenith, it is as far from the horizon as it gets. At the equator, when the sun is at the zenith, it is right overhead.
30 degrees for observers at a latitude of 30 degrees north

It means angle.
The Zenith Angle has 341 pages.
The Zenith Angle was created in 2004-05.
solar altitude angle= (90 degree - zenith angle )

Zenith is in a 90 degree angle and Horizon is a left and right direction
90 degrees.

If I understand the question, then it includes a false statement.The angle between an object and the horizon is the object's 'elevation' angle.'Zenith' is a point in the sky . . . the point directly over your head, whoseelevation angle is 90 degrees regardless of which direction you're facing..
By definition at mid day
The definition of critical angle is the angle of incidence that refraction can still occur.
