Artist 52 [7]

Answer:

<u>Searching For Facts</u>

  • You must first begin surfacing the net or other sources for facts about the Topic provided.
  • It also quite depends on the size of the scientific report you are preparing. (It is usually large about 4000 words).
  • If you are abundant with information, about the topic, write To-The-Point.
  • If there is a lack of information, try to expand about a sub-topic whilst including new facts about the same.

<u>Constructing a report:</u>

  • You can start with an appropriate title about your topic, just ensure that it doesn't go too long.
  • Begin the report with a short introduction about the report. If you are noting an experiment, include the apparatus required.
  • The body should provide a detailed description about the topic. You may use tables or paste images in the report.
  • If it's a report about an experiment, don't forget to write down the observations.
  • Lastly, a conclusion with a brief thought derived, must be included in the report.
  • If necessary, attach the References in the report too.

How does change in temperature occur depending on the altitude in troposphere and stratosphere?​
Shalnov [3]

Answer:

The temperature decreases with the rise in altitude in the troposphere.

The temperature increases with the rise in altitude in the stratosphere.

Explanation:

  • Troposphere is the  layer of atmosphere, closest to the ground.
  • It has maximum number of gases.
  • Troposphere gets heated up due to the radiations reflecting back from earth.
  • That means the layer of troposphere nearer to the earths surface is warmer than the higher layers.
  • Thus the temperature decreases with rise in altitude in the troposphere.
  • Troposphere is followed by a troposphere. This is a transition zone between troposphere and stratosphere. Here no changes takes place with rise in altitude.
  • Second layer of atmosphere, that lies next to troposphere is stratosphere.
  • Stratosphere has similar composition as that of the troposphere except for the presence of the layer of ozone in it.
  • The stratosphere gets heated up due to the trapping of heat by the ozone layer.
  • Ozone gets heated up due to the ultraviolet radiations of the sun.
  • That means the higher layers of the stratosphere is more heated up than the lower layers.
  • Thus, With increase in altitude the temperature also increases in the stratosphere.
