Answer:
Natural groundwater recharge occurs as precipitation falls on the land surface, infiltrates into soils, and moves through pores spaces down to the water table. Natural recharge also can occur as surface water leakage from rivers, streams, lakes, and wetlands or For example groundwater can be artificially recharged by redirecting water across the land surface through canals, infiltration basins, or ponds; adding irrigation furrows or sprinklers systems; or simply injecting water directly into the subsurface through injection wells.
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.

Answer:
Option (D)
Explanation:
Historical geology usually refers to the study of the changes and the variation that occurs at or below the surface of the earth. In simple words, it mainly involves the study of past events. This includes the variation and evolution of different life forms that existed on earth over a time of about 3.8 billion years until the present. It basically comprises the important part of geology namely Paleoclimatology, Paleontology and Paleoseismology. This historical geology is also known as Paleogeology.
Thus, historical geology involves the biological changes that occur over a definite time.
Thus, the correct answer is option (D).
Answer: c. paleomagnetic data from ocean crust
Explanation:
Alfred Wegener was a German meteorologist and geophysicist, who in 1915 published his work <em>"The Origin of Continents and Oceans"</em> with a hypothesis that was radical for his time.
In this publication he proposed that during the end of the Paleozoic period and the beginning of the Mesozoic period the land masses were united in a single supercontinent, which he called <u>Pangea</u>, which was surrounded by a huge ocean, which he called <u>Panthalassa</u>. As proof of this, he was based on the way in which the coasts of Africa and South America seemed to fit on each side of the Atlantic Ocean, as if it were a puzzle. In addition to <u>the distribution of certain geological formations, native flora and fauna and the fossils found in the northern continents and places currently geographically far from each other. </u>
At the time, this idea was not accepted and Wegener was ridiculed by the scientific community, because despite its evidence, in its publication did not explain how those land masses moved.
Years later, in the decade of 1960, the theory of plate tectonics related to the movement of the continents according to the paleomagnetic evidence was developed and it was shown that Wegener was right.
