Answer:
The earth undergoes various types of geological processes that control different conditions on the earth's surface. When these processes are very severe along with human activities, then the organisms and humans have to face a lot of difficulties. Due to the occurrence of heavy flood in any region, the people lose their houses, the agricultural crop fields are affected by losing their fertility. Water is one of the essential elements for the survival of life and it creates havoc when they are contaminated because they become unfit for drinking. So a lot of problems is needed to be faced due to natural calamities like floods, tsunamis, and droughts.
Human beings can meet up the challenges of these impacts by undertaking certain steps-
(1) The waster materials produced from the industries and factories must be collected and dumped somewhere instead of allowing it to get mixed up with the rivers and streams.
(2) The dams must be properly constructed and should be periodically surveyed.
(3) Water must be preserved and make proper and minimum use of it.
(4) Pollution must be reduced as much as possible.
(5) Afforestation must be done so that the plants and trees can hold the soil and maintain its fertility, rather than getting eroded.

Answer:
The luminosity of both the stars is same star A is closer to the planet Earth as compared to star B.
Explanation:
From the mentioned case we can infer that the most accurate relation between the stars and the astronomer on earth observing for over a period is that the luminosity of the stars is same.
The more drawn out the pulsation time frame, the more brilliant the star. The period-luminosity connection for old style Cepheid was found in 1908 by Henrietta Swan Leavitt in an examination of thousands of different stars in the Magellanic Clouds.
Colliding boundaries are convergent so the boundary would be convergent.
