What is the concentration of ozone in the stratosphere?
The concentration of ozone varies with altitude. Peak concentrations, an average of 8 molecules of ozone per million molecules in the atmosphere, occur between an altitude of 30 and 35 kilometers. Ozone in the stratosphere absorbs most of the ultraviolet radiation from the Sun.
What percentage of the atmosphere is good ozone?
Stratospheric “good” ozone. That may seem like a lot, but it is only 0.00006 percent of the atmosphere. The peak concentration of ozone occurs at an altitude of roughly 32 kilometers (20 miles) above the surface of the Earth. At that altitude, ozone concentration can be as high as 15 parts per million (0.0015 percent).
What is an ozone peak?
Peak concentrations, an average of 8 molecules of ozone per million molecules in the atmosphere, occur between an altitude of 30 and 35 kilometers. Ozone in the stratosphere absorbs most of the ultraviolet radiation from the Sun. Without ozone, the Sun’s intense UV radiation would sterilize the Earth’s surface.
What is a dangerous level of ozone?
Tropospheric “bad” ozone. In the troposphere near the Earth’s surface, the natural concentration of ozone is about 10 parts per billion (0.000001 percent). According to the Environmental Protection Agency, exposure to ozone levels of greater than 70 parts per billion for 8 hours or longer is unhealthy [1].

In which temperature zone of Earth's atmosphere is the polar jet stream located?
The 50°-60° N/S region is where the polar jet located with the subtropical jet located around 30° N . Jet streams vary in height of four to eight miles and can reach speeds of more than 275 mph (239 kts / 442 km/h ).
In which temperature zone of Earth's atmosphere will most meteors burn up?
Above the stratosphere is the mesosphere. It extends upward to a height of about 85 km (53 miles) above our planet. Most meteors burn up in the mesosphere.
What is the approximate distance from the Sun to the asteroid belt Regents?
13. The center of the asteroid belt is approximately 503 million kilometers from the Sun. Draw an X on the model between two planets to indicate the center of the asteroid belt.
Which event occurred approximately 4.6 billion years ago?
The hydrogen protons began fusing, forming helium and releasing massive amounts of energy. This led to the formation of the star that is the center point of our solar system—the sun—roughly 4.6 billion years ago. The formation of the sun consumed more than 99 percent of the matter in the nebula.
In which layer of the atmosphere do we find ozone layer?
the stratosphereThe ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth's surface, in the stratosphere.
What temp is the stratosphere?
In this region the temperature increases with height. Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere.
How long would it take for a spaceship to get to the asteroid belt?
With current technology the journey to the asteroid belt would be greater than 18 months, suggesting that a crewed mission may be beyond our current technological capabilities.
What is bigger than a solar system?
From largest to smallest they are: Universe, galaxy, solar system, star, planet, moon and asteroid.
How long would it take to get to the asteroid belt at light speed?
It will take between 26.7 and 35 26.7 and 35 minutes to travel at light speed from Earth to the asteroid belt.
How the Earth evolved in the last 4.6 billion years?
The Sun and its family of planets formed when a cloud of dust and gas condensed 4.6 billion years ago. Several hundred million years after the Earth took form, an outer crust developed. But these surface rocks are no longer available for study: they have disappeared into the interior of our dynamic planet.
How much old is our world?
4.54 billion years oldEarth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date. In northwestern Canada, they discovered rocks about 4.03 billion years old.
Which allowed scientists to determine that Earth was at least 4.3 billion years old?
By dating the rocks in Earth's ever-changing crust, as well as the rocks in Earth's neighbors, such as the moon and visiting meteorites, scientists have calculated that Earth is 4.54 billion years old, with an error range of 50 million years.
What meteor burns up in Earth's atmosphere?
When meteoroids enter Earth's atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.
What is the temperature of meteors?
3000 degrees FahrenheitThe small stuff is often dust left by a passing comet. When they plow through the atmosphere, meteors are heated to more than 3000 degrees Fahrenheit, and they glow. Meteors are not heated by friction, as is commonly thought.
Do most meteors burn up in the atmosphere?
Most (between 90 and 95 percent) of these meteors completely burn up in the atmosphere, resulting in a bright streak that can be seen across the night sky, Moorhead said. However, when meteors survive their high-speed plunge toward Earth and drop to the ground, they are called meteorites.
How far is the North Pole from the Equator?

How much ozone is in the atmosphere?
The total mass of ozone in the atmosphere is about 3 billion metric tons. That may seem like a lot, but it is only 0.00006 percent of the atmosphere. The peak concentration of ozone occurs at an altitude of roughly 32 kilometers (20 miles) above the surface of the Earth.
How high is ozone?
At that altitude, ozone concentration can be as high as 15 parts per million (0.0015 percent). The concentration of ozone varies with altitude. Peak concentrations, an average of 8 molecules of ozone per million molecules in the atmosphere, occur between an altitude of 30 and 35 kilometers.
How long is ozone bad for you?
According to the Environmental Protection Agency, exposure to ozone levels of greater than 70 parts per billion for 8 hours or longer is unhealthy [1]. Such concentrations occur in or near cities during periods where the atmosphere is warm and stable.
How is ozone created?
In the lower atmosphere (the troposphere) near the Earth’s surface, ozone is created by chemical reactions between air pollutants from vehicle exhaust, gasoline vapors, and other emissions. At ground level, high concentrations of ozone are toxic to people and plants.
What is the best place to find ozone?
Stratospheric “good” ozone. Ninety percent of the ozone in the atmosphere sits in the stratosphere , the layer of atmosphere between about 10 and 50 kilometers altitude. The natural level of ozone in the stratosphere is a result of a balance between sunlight that creates ozone and chemical reactions that destroy it.
Where is UV radiation absorbed?
Solar ultraviolet radiation is largely absorbed by the ozone in the atmosphere —especially the harmful, high-energy UV-a and UV-b. The graph shows the flux (amount of energy flowing through an area) of solar ultraviolet radiation at the top of the atmosphere (top line) and at the Earth’s surface (lower line).
Does ozone have UV C?
Ozone screens all of the most energetic, UV-c, radiation, and most of the UV-b radiation. Ozone only screens about half of the UV-a radiation. Excessive UV-b and UV-a radiation can cause sunburn and can lead to skin cancer and eye damage.
