Because the rest is reflected, absorbed, or scattered by the atmosphere and the things in it.
An increase in cloud cover or an increase in atmospheric particulates like aerosols would lead to a decrease in the amount of insolation absorbed at Earth's surface by reflecting more sunlight back to space before it can reach the surface.
Insolation refers to the amount of solar radiation received on a particular surface. Insolation temperature lag refers to the delay between the peak solar radiation and the peak temperature on a surface, as heat absorption and release processes take time to reach equilibrium. This lag can vary depending on factors like the material of the surface and its thermal properties.
It attempts to reach the surface of the Earth.
Surface waves are formed when waves reach the Earth's surface. These are seismic waves that travel along the Earth's surface and can cause the most damage during an earthquake.
More reach the surface of the moon because there is no atmosphere to heat and burn them up.
The lower solar angles in high latitude locations lead to lower levels of insolation because of how the earth tilts on its axis. The rays from the sun have less distance to travel before they reach the earth's surface.
Shooting stars that reach the Earth's surface are called meteorites. These are fragments of asteroids or other celestial bodies that survive the journey through Earth's atmosphere and land on the surface.
CFC's
The ozone hole allows some radiations to reach the earth's surface. These radiations are high energy UV radiations.

The Sun doesn't reach Earth's surface; the Sun stays right where it is, in the center of our Solar System.The Sun's light takes about 8 minutes to reach Earth (150 million km. / 300,000 km/second).The Sun doesn't reach Earth's surface; the Sun stays right where it is, in the center of our Solar System.The Sun's light takes about 8 minutes to reach Earth (150 million km. / 300,000 km/second).The Sun doesn't reach Earth's surface; the Sun stays right where it is, in the center of our Solar System.The Sun's light takes about 8 minutes to reach Earth (150 million km. / 300,000 km/second).The Sun doesn't reach Earth's surface; the Sun stays right where it is, in the center of our Solar System.The Sun's light takes about 8 minutes to reach Earth (150 million km. / 300,000 km/second).
