The type of solar weather during which we can predict power grid operations on Earth to degrade is Coronal Mass Ejections
Coronal Mass Ejections are what we call the sudden bursts of plasma and charged ions released from the suns solar corona. These CMEs tend to occur during solar flares and release the charged ions into the solar wind.
Despite the presence of all of the options during a solar storm, the correct option is option 3, Coronal Mass Ejections because without the presence of the CME , solar wind and flares are not dangerous to the Earth. The charged ions from the CME collide and warp the Earth's magnetic field, removing it's protection and causing <u>power grid failures and radio communication disruptions throughout the Earth.</u>

Answer:
The material through which a wave travels is called a medium
Explanation:
Answer:
The correct answer will be option-D
Explanation:
Acid deposition is the process by which the acid formed in the atmosphere falls off with the rain and gets deposited in the lithosphere.
The deposition of the acid in the soil causes many adverse effects on the living organisms especially plants as deposition of acid leads to the reactions which result in the release of the elements from their compounds via a process known as "leaching".
The leaching of the elements leads to the decrease in the fertility of the soil and thus productivity of the plants or crops.
Thus, option-D is the correct answer.
Answer:
Yes
Explanation:
When you put any force on an object (depends on how much mass it has), it should be moved by the force.
It wasn't that the favourable traits were passed down through generations of species, it's that natural selection removed the species who simply couldn't survive. Here's an example: There are two species of moth in a forest, one is brown and the other is black. The trees in the area have trunks that are brown like the moth's wings, so it can camouflage very well compared to the black moths. Eventually, more black moths were being eaten by various amphibians and bugs than brown moths. So, the favourable trait of brown wings continued to be passed on, whereas the black wings went extinct as they were all eaten. Hope that helped :D
