Answer:
Option (A)
Explanation:
The Precambrian represents the time period, right from the beginning of the earth to about 540 million years back. It is divided into 3 parts, namely the Hadean, the Archean and the Proterozoic. Throughout this geological time, vast changes have taken place on earth. The first life forms of about 3.8 billion years old, that existed on earth were the simple unicellular organisms, whose traces were only found at some particular places. These organisms were very small and are comprised of soft bodies, so they were affected by the earth's dynamic processes. The organisms in order to get fossilized must contain hard parts. Due to the presence of soft bodies, the organisms were not fossilized and so it took a long time to demarcate that the late Precambrian organisms were animal-like life.
hence, the correct answer is option (A).
Water that falls as precipitation<span> flows along the surface of the ground. This surface water infiltrates into the ground surface and is held in </span>soil pore spaces<span> and in the fractures of rock formations. Gaining access to groundwater sources therefore requires digging or drilling through the ground and into an aquifer.</span>
There are many ways they can disrupt their new environments.
They can often carry diseases or parasites that native species are unequipped for. A good example of this is cats being brought to Australia, a continent with no native felidae. Cats are one of the main carriers of toxoplasmosis and many species in Australia had not evolved alongside felidae and were relatively unequipped to handle these parasites if their immune system was vulnerable.
They can also cause issue simply because they are so different, and the animals and plants living I. These areas are simply unable to defend themselves or keep up as a result. Such as pigs (and other animals brought over by humans) eating dodo bird eggs (these birds roosted on the ground) and domestic cats overhunting for sport.
Hope this helps a bit! It's a pretty broad topic and definitely one worth researching even more
Answer:
Energy is transferred through the oceans, the atmosphere, and the geosphere by convection. Energy is transferred between the geosphere and the atmosphere by conduction.
