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.
Why do satellites need to reach a specific speed to escape earths surface?
Satellites need to reach a specific speed, known as escape velocity, to overcome Earth's gravitational pull and enter orbit or travel into space. This speed, approximately 11.2 kilometers per second (about 25,000 miles per hour), allows them to break free from the gravitational attraction without falling back to Earth. Achieving this speed ensures that the satellite can maintain a stable trajectory and avoid being pulled back by gravity. If a satellite doesn't reach this speed, it will not be able to escape Earth's atmosphere and will eventually descend back to the surface.
The deepest scientist have been able to study earths interior depth in Km?
The deepest scientist have been able to study earths interior depth is 12,262 meters
Why are UV rays from the sun able to reach earth's surface?
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.
As the amount of ozone in the stratosphere decreases what happens?
As the amount of ozone in the stratosphere decreases, more harmful ultraviolet (UV) radiation from the sun can reach Earth's surface. This can lead to increased health risks for humans, such as skin cancer and cataracts, as well as harm to marine life and ecosystems. Ozone depletion also affects weather patterns and can contribute to climate change.
What is one reason that ozone near the earths suface is dangerous?
Since stratospheric ozone is produced by solar UV radiation, one might expect to … Consequently, unabsorbed and dangerous ultraviolet-B radiation is able to reach the Earth's surface .
Is air pressure greater near the earths surface or at higher altitudes?
I am sure that if you think about the problems encountered by climbers on Mount Everest you might be able to answer that yourself. Near the Earth's surface.

Why is it important for geologists to understand how water moves beneath earths surface?
So that they are able to make decisions about how groundwater can be used without damaging this valuable resource

What planet is Venus of?
The surface composition of Venus is believed to be similar to Earths, largely silicon based rock. Its difficult to say exactly what the surface is as space craft cannot survive long enough on its surface to be able to analyse and send back detailed information.
Do you die in quicksand?
Yes you would because the sand would suck you in until you can no longer reach the surface. Therefore you wouldn't be able to breath

Is the earths surface made up of entirely iron and nickel?
You are thinking of the Earth's core, which is primarily iron, with nickel and a variety of other elements in smaller percentages; the Earth's surface has a much more varied chemical composition, which you should be able to observe, since we all live on the surface.
Can you get closer to the sun or the earths core?
You are already closer to the earths core than you will ever be able to get to the sun
How does light affect organisms lives?
When there is less light, plants may not be able to photosynthesis especially the aquatic plants because if there is very little sunlight, it would not be able penetrate through the water surface to reach the plants that are under the water surface and thus many plants will not be able to make food and will eventually die.
