Answer:
The main conclusion that can be determined by observing the map of Africa is that the borders of the nations of modern Africa were determined by the colonial powers that distributed the territories of the continent after the Berlin Conference. Thus, the present borders of the continent do not respect the historical nationalities that the African tribes give each other, with which ethnic conflicts occur in many of these nations, especially in central Africa. Thus, although today it is a practically impossible situation, in case of wanting to respect the historical nationalities of the peoples of the continent, the current national borders should be modified taking into account the ethnic, social and cultural differences of its inhabitants.
Answer:
"The tilt of the Earth's spin axis with respect to the plane of its orbit about the sun (the ecliptic plane) is important for a habitable Earth. The Earth's spin axis is tilted 23.5° with respect to the ecliptic, giving moderate seasons and preventing temperature extremes anywhere on the planet"
Explanation:
A biome is defined as the large ecological area where the formation of plants and animals with common characteristics gather due to the similar climates. If I were an ecologist, and i will be determining whether an entire river and lake biome is being threatened by human activity, the indicator species that i might look for are the ones that have been introduced into the biome.

During a full or new moon, when the Earth, moon and sun align, spring tides form, creating higher and lower than normal tides. During the first- and third-quarter moon phases, when the moon and sun are at right angles to the Earth, neap tides occur, creating low and high tides with minimal difference in heights.
The correct answer is - Seafloor spreading at the mid-ocean ridge provides the mechanism for tectonic plate movement.
Harry Hess is one of the people that is most important when it comes to the proving and world wide acceptance of the continental drift theory.
Hess was very interested in the topic, and he was constantly looking for clues that would bring light to it and finally have a definite proof of it. While sailing through the Atlantic and doing some examinations, Hess noticed that there high mountains in the water, having flat peaks, and being arranged in an interesting manner. These underwater mountains, named guyouts, were the highest at a certain point, and than on both sides, as the distance was increasing they were becoming smaller and smaller.
What Hess stumbled upon was the seafloor spreading and how it works, and he recognized that quickly. He immediately went on to share what he discovered, that there's magma coming from bellow, solidifying and spreading, thus creating new crust while pushing the old crust away from the center, which is the reason why the continents are moving.
