UV rays from the sun can reach Earth's surface because they are part of the electromagnetic spectrum and travel in waves. While some UV radiation is absorbed by the ozone layer in the stratosphere, a significant portion still penetrates through this layer and reaches the ground. Factors such as altitude, latitude, and cloud cover can influence the amount of UV radiation that actually reaches the surface. This is why UV protection is important, even on cloudy days or at higher altitudes.

How are ultraviolent rays fron the sun are able to reach earths surface?
Ultraviolet (UV) rays from the sun travel through the vacuum of space and reach Earth’s atmosphere. While some UV radiation is absorbed by the ozone layer, which protects the surface from harmful effects, a portion still penetrates through. This allows UV rays to reach the Earth's surface, contributing to processes like photosynthesis and skin tanning, but also posing risks such as skin cancer and eye damage.
How are ultraviolet rays from the sun able to reach Earth's surface?
Ultraviolet rays from the sun are able to reach Earth's surface because they have shorter wavelengths compared to visible light and can penetrate the atmosphere. While some UV radiation is absorbed or scattered by the atmosphere, enough reaches the surface to cause effects such as sunburn and skin damage.
What happens to ultra violet rays as they reach earths surface?
As ultraviolet (UV) rays from the sun reach Earth's surface, a significant portion is absorbed by the ozone layer in the stratosphere, which protects living organisms from harmful effects. The remaining UV radiation that reaches the surface is primarily UV-A and a smaller fraction of UV-B, both of which can cause skin damage and increase the risk of skin cancer. Additionally, UV rays can contribute to environmental effects, such as affecting ecosystems and degrading materials like plastics.
What effect does the earths magnetic field have on the intensity of cosmic rays striking the earths surface?
The Earth's magnetic field acts as a shield, deflecting charged particles (cosmic rays) away from the surface. This helps reduce the intensity of cosmic rays reaching the Earth's surface. However, cosmic rays can still penetrate the atmosphere at higher latitudes where the magnetic field is weaker.
X-ray telescopes are located in orbit around the Earth because?
X-ray telescopes are placed in orbit around the Earth to avoid absorption of X-rays by Earth's atmosphere. By being in space, these telescopes can capture high-energy X-ray emissions from celestial objects that do not reach the surface due to the atmosphere.

What is the effect of solvents on the air?
Solvents take away the ozone layer, letting UV rays reach the Earths surface easier.
Do any gamma rays at all make it to the surface of Earth?
Almost all gamma rays are absorbed by the Earth's atmosphere, or deflected by the magnetosphere, but some do manage to get through. Those that reach the surface of the Earth are mostly secondary comic rays, which are produced when gamma rays or primary cosmic rays hit the top of the atmosphere.
What kind of radiation passes through the atmosphere and reaches the earths surface?
Most of the visible light and some of the ultraviolet and infrared radiation from the sun pass through the atmosphere and reach the Earth's surface. Other forms of radiation, such as gamma rays and X-rays, are mostly absorbed by the atmosphere and do not reach the surface.

When the suns rays strike the earths surface energy is absorbed or reflected?
absorbed
What layer of the atmosphere protects the earths surface from UV rays?
The Ozone layer.
What is the colder at high latitudes because the sun's rays strike earths surface at a angle there?
Oblique

What is the name for the effect that is produced when warm air near earths surface bends light rays?
greenhouse effect
How does sun cream protect from the UV rays of the sun?
The cream is opaque and reflects the UV rays before they reach the skin's surface.
