Answer: A. Air bubbles trapped in a layer indicate how much CO2 was in the atmosphere the year the layer formed.
Explanation:
When ice cores were formed, they included air bubbles that got stuck during the formation. Scientists can study these air bubbles to find out how much carbon dioxide is in them as this will show the proportion of carbon dioxide in air at the time the core was formed.
They can then compare those figures to current carbon dioxide levels to see if there has been a change. This change will give proof of climate change.
Switching a lot of our energy consumption to renewable forms would significantly help the planet because it doesn’t put out pollution or waste, and doesn’t use the resources we are low on like coal or gas. Forms of renewable energy to switch to would be solar energy, wind energy, or hydroelectricity.
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.
