Answer: According to the big bang theory, the galaxies, the solar system, the planets, all started from a single point, commonly known as the Singularity. From that point, the universe is continuously expanding and this is the reason why the galaxies, and other distant galaxies are moving further. The space itself is expanding more and more with time.
Explanation:
Tectonic Earthquakes
Earthquakes caused by plate tectonics are called tectonic quakes. They account for most earthquakes worldwide and usually occur at the boundaries of tectonic plates.
Plate tectonics
Induced Earthquakes
Induced quakes are caused by human activity, like tunnel construction, filling reservoirs and implementing geothermal or fracking projects.
Volcanic Earthquakes
Volcanic quakes are associated with active volcanism. They are generally not as powerful as tectonic quakes and often occur relatively near the surface. Consequently, they are usually only felt in the vicinity of the hypocentre.
Collapse Earthquakes
Collapse quakes can be triggered by such phenomena as cave-ins, mostly in karst areas or close to mining facilities, as a result of subsidence.
Answer:
Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, but since the 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels (like coal, oil, and gas) which produces heat-trapping gases, which is global warming.

Both tundra and deserts receive very little precipitation, and it can even happen that some places in a tundra receive more precipitation than some places in a desert! As a result the plants in both tundra and a desert have a waxy coating on leaves. - The correct answer is c.
