Answer:
the positive and negative effects that occur when people interact with their environment.
Answer:
The ozone layer is usually referred to as a blanket that protects the earth from the harmful incoming solar radiation. It is located in the Stratosphere layer but also there is another ozone layer in the troposphere, commonly known as the troposphere ozone.
The stratospheric ozone is considered to be good ozone because it is located at a high altitude and it directly acts as a shield protecting the earth from the solar radiation, which can cause various types of skin diseases and also can increase the surface temperature of the earth.
On the other hand, the troposphere ozone is considered to be bad as it is located near to the ground surface and is mainly comprised of the greenhouse gases, that are harmful to the atmosphere and also increases the surface temperature of the earth.
CFC is one of the greenhouse gases that are harmful to the atmosphere because CFC molecules are continuously hit by the solar radiations that breaks the bond between the carbon and chlorine, resulting in the production of a single Chlorine atom, which eventually breaks down down the ozone layer by reacting with it. This is how the CFCs depletes the stratospheric ozone.
The depletion of the ozone layer leads to the global climatic changing, affecting all the biotic and abiotic components of the earth. This is a long term effect. This global warming is a threat to destroy the earth, so preventive measures must be taken in order to reduce the causes and use of those substances that can lead to catastrophic changes.
Answer:
1. disk
2.halo
3. globular cluster
4.spiral arm
5. spiral galaxy
6. bulge
Explanation:
1. In Spiral or Lenticular galaxies, the galactic disk is the flat portion that consists of 2 components; the stellar component and the gaseous component. The stellar component consists of the galaxy stars while the gaseous component consists of cool gas and dust.
2. The galactic halo is the first portion of the galaxy to be formed. Formation of halos is caused by increased gravitational effects and the presence of primordial black holes. When baryonic and dark matter merges, halos are formed.
3. A globular cluster is a large compact spherical star cluster, typically of old stars in the outer regions of a galaxy.
4. Spiral arms are region of a large concentration of stars in a spiral galaxy. This large concentration of stars are usually very bright and easily noticeable.
5. The Milky Way galaxy consists of flat, rotating disk containing stars, gas and dust, and a central concentration of stars known as the bulge. The spiral arm that I explained above extends from the center of spiral galaxies. This extension makes it resemble a spiral and thus give spiral galaxies their name.
6. The bulge is a large concentration of stars.
