Answer: The structure and curvature of the Earth results in beams of sunlight glancing off the equator and reaching other areas of the Earth. This means that the areas at the equator receive more energy as the sun's rays hit them directly. :)
Answer:
:/ what about it? is this your question? if so you need to add more detail then that so people know what your talking about
Explanation:
Answer:
composition of meteorites
Explanation:
The continental drift theory has been based upon several evidence. The shape and perfect fit of South America and Africa is one of those evidence. The fossil records are another very strong evidence, as there are fossils of the same species on different continents that are not connected to each other in the present, and in nature is practically impossible to have the same species in different continents. The evidence about the climate also suggests that the continents have been moving, as there are remains of glaciers at places that nowadays are deserts and savannas. The meteorites are not one of the evidence though, and their composition doesn't have anything to offer in this tehory, as their composition is not related to the Earth and the processes on it.
The answer is B. Cnidarians
Cnidarian body has no left or right side, only tom and bottom surfaces. If you divide cnidarian a about central point, you will get equal parts. So, cnidarians are radially symmetrical animals. This group includes hydroids, jellyfish, anemones, and corals. In all groups, animals have stinging cells on tips of tentacles. They use them to capture the prey. Their name literally means stinging creatures.
