Answer:false its not true
Answer:
The most likely explanation is that the star is a member of an eclipsing binary star system.
Explanation:
An eclipsing binary star system takes place when two stars which are close to each other move in an orbit in which sometimes, one star can hide the light behind the other.
There are two types of eclipses depending on the orientation of the orbit and the size of the stars: the totals or the annular ones. It may also be the case that the eclipses are partial.
<em>Algol </em>is the best known eclipsing binary star, and the first of this kind to be discovered. Its interval between eclipses is 173 hours (2.9 days).
When this type of eclipses happens, the brightest star provides 92% of the light of the system, while the eclipsed only contributes less than 8%, and there is a third star, which is not eclipsed.
Therefore, if there is any star that has been bright most of the time, and during certain time intervals it becomes dimmer, that star is being overshadowed.
<span>Wegener had the evidence that there are similar rock formations on different continents and that the shape and rock formations of continents on either side of an ocean fit quite nicely. However, he could not find the mechanism that caused the continents to move across the ocean floor. I hope this helps. :)</span>

Explanation:
Importance of troposphere to life on earth
The study of the troposphere is very important because we breathe the air in this layer of air. ... Tropospheric processes, such as the water or hydrologic cycle (the formation of clouds and rain) and the greenhouse effect, have a great influence on meteorology and the climate.
The force of gravity increases - when an objects mass increases.
Weight is - caused by gravity affecting mass.
Mass is - the amount of matter in an object.
The force of gravity decreases - when distance increases.
