Answer:
I believe that climate change is one of the most serious problems of young generations. At the current pace of greenhouse gas production global warming will increase exponentially, which will result in rising sea levels, certain animal species going extinct. Deforestation also severely adds to this problem as wood is a finite resource on Earth and the more trees we destroy the less oxygen there is relative to the amount of carbon dioxide in the atmosphere. This will continue to weaken the ozone layer which could result in catastrophe from sun flares or radiation. I do believe that in the near future drastic measures will be taken to prevent these events.

Answer:
The correct answer - The Gas giants are much much larger in size.
Explanation:
There are two distinct types of planets that are four rocky planets and four gas giants plants. Mercury, Venus, Earth, and Mars are four rocky planets, and Neptune, Uranus, Saturn, and Jupiter are four gas giants.
The Gas giants plants are much much larger in size in comparison to the rocky planets. It is because rocky planets have relatively low gravity than gas giants and were not able to attract large amounts of gas to their atmospheres.
Thus, the correct answer - The Gas giants are much much larger in size.

Answer:Spectroscopy helps astronomers to determine the composition, temperature, density, and motion of an object.
Infrared spectroscopy helps to identify the atoms and molecules in the object.
The red shift or blue shift (Doppler Effect) in a spectral line tells how fast the object is receding from Earth or coming toward it.
The Doppler shift enables astronomers to discover extrasolar planets.
As a planet orbits its star, the star is alternately moving away from or toward us.
Astronomers can use the Doppler shifts to calculate the speed of the star and the mass of the planet that is tugging on it.
