It's not! The heat (infrared) energy reaching Earth's surface is many times
more than the energy in the visible range ... the visible is practically negligible
in comparison, and then you have the energy in all the other electromagnetic
bands in addition.
Ozone
Ozone in the atmosphere blocks most of the UV radiation from the Sun... Without it's protection - the planet would overheat.
Infrared radiation
Visible light is an insignificant portion of the solar radiation that warms the Earth. The sun's infrared radiation, also known as 'heat', is responsible for virtually all of it.
Yes, reflection and absorption by the atmosphere can prevent some ozone from reaching Earth's surface. Ozone in the stratosphere absorbs much of the sun's ultraviolet (UV) radiation, protecting the Earth's surface from harmful UV rays. However, some ozone does reach the surface, where it can also have positive effects, such as reducing air pollution.
Ozone
commonly 'sunlight', but more specifically UltraViolet radiation
It blocks (some of) it from reaching the surface of the Earth.
Visible light and infrared radiation are mainly reflected away from the Earth's surface. These wavelengths are absorbed by the atmosphere and then reflected back out into space, helping to regulate Earth's temperature.
Albedo refers to the reflectivity of a surface. Surfaces with high albedo reflect more solar radiation back into space, which can cool the Earth's surface and lower temperatures. Surfaces with low albedo absorb more solar radiation, leading to warming of the Earth's surface.

the greenhouse effect!
The Sun is the primary source of radiant energy that emits electromagnetic radiation toward Earth's surface, including visible light, infrared radiation, and ultraviolet radiation. This energy is essential for sustaining life on Earth through processes like photosynthesis and heating the planet.
Atmospheres have many different purposes, however the Earths atmosphere is vital to its existense as it prevents the suns harmful radiation from reaching the Earths surface. Moreover, from an enviromental standpoint the errosion by pollutants will eventually destroy the delicate atmosphere and the Earths protective barrier will be gone.
Oxygen in the atmosphere helps to absorb and scatter incoming ultraviolet (UV) radiation from the sun. This process occurs in the stratosphere, where oxygen molecules break apart the incoming UV radiation. This absorption and scattering of UV radiation by oxygen prevent a large amount of harmful UV radiation from reaching the Earth's surface.
