Which layer block the harmful ultraviolet rays from the sun?

The ozone layer
The ozone layer protects us from potentially harmful ultraviolet (UV) radiation.

Which layer protects Earth from harmful rays of the sun?

ozone layer
The stratospheric ozone layer is Earth’s “sunscreen” – protecting living things from too much ultraviolet radiation from the sun. The emission of ozone depleting substances has been damaging the ozone layer.

Which layer protect us from the scorching heat of the sun?

The correct answer is Ozone. The Ozone is a gas composed of three atoms of oxygen (O3).

How does the ozone layer block ultraviolet rays?

Ozone absorbs UV-B radiation from the sun. When an ozone molecule absorbs UV-B, it comes apart into an oxygen molecule (O2) and a separate oxygen atom (O). By absorbing UV-B in the stratosphere, the ozone layer prevents harmful levels of this radiation from reaching Earth’s surface.

Who protects the Earth from the harmful rays of the sun and the scorching heat?

Which layer protect us from the scorching heat of the sun atmosphere biosphere hydrosphere?

The atmosphere is the thin layer of air that surrounds the earth. The gravitational force of the earth holds the atmosphere around it. It protects us from the harmful rays and scorching heat of the sun. It consists of a number of gases, dust and water vapours.

How does the sun affect the ozone layer?

Solar changes. The formation of stratospheric ozone is initiated by ultraviolet (UV) radiation coming from the Sun (see Figure Q2-1). As a result, an increase in the Sun’s radiation output increases the amount of ozone in Earth’s atmosphere.

What layer is the ozone layer in?

the stratosphere
Most atmospheric ozone is concentrated in a layer in the stratosphere, about 9 to 18 miles (15 to 30 km) above the Earth’s surface (see the figure below). Ozone is a molecule that contains three oxygen atoms. At any given time, ozone molecules are constantly formed and destroyed in the stratosphere.

Which layer protects us from harmful rays of the sun lithosphere hydrosphere atmosphere biosphere?

The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. When the sky is clear, there is an inverse relationship between stratospheric ozone and solar UVR measured at the Earth’s surface.

Who protects the Earth from the harmful rays and the scorching heat of the sun?

How does the atmosphere block UV rays?

A layer of ozone in the upper atmosphere absorbs UV radiation and prevents most of it from reaching the Earth. This means that more ultraviolet radiation can pass through the atmosphere to the Earth’s surface, particularly at the poles and nearby regions during certain times of the year.
