Answer:
b. measuring the pulsations of the Sun from stations around the world.
Explanation:
The Global Oscillation Network Group (GONG) is a community-based program that wants to conduct a detailed study of the internal structure of the sun by using helioseismology. GONG relies on a team of six observatories around the world to perform its work. One of the duties of GONG is to measure the pulsations of the Sun from six stations located all over the world.
I would say D is NOT one of the reasons why life is found only on Earth
Answer: Super cell thunderstorm
Explanation: When cold and warm air masses collides with each other, balancing the total air mass, then this condition is called the stationary front. This front often creates heavy flooding occurring in a particular region with heavy thunderstorm, which is known as the super cell thunderstorm.
Super cell thunderstorm are enormous, destructive storms which are formed due to the instability in the air masses, moisture content in the air masses, wind speed as well as lifting mechanism of the air mass. It is the strongest of all the thunderstorm types.
Thats because on the side of the moon that's facing the Earth, gravity is more powerful on this side, thus, the moon's gravity pulls the ocean's water in this direction, which is called a bulge. On the other side of the moon, inertia is the one that's powerful, this also creates a bulge. These two forces creating bulges at the same time is what causes multiple high tides.
Hope this helps!
