Answer:
1. Air- We humans and other living creatures depend on air for staying alive, humans, animals and plants all need air to breathe, it’s the main thing that keeps us alive and growing on.
2. Soil- We depend on soil for vegetations and these vegetations keep us alive, it also prevents plants roots from getting out of place and they hold water and nutrients.
3. Water- helps to transport nutrients in our body and regulates the body heat. Without water, the ground will soon become bare and will start to crack, many living organisms will start dying from thirst too.
4. Fire- It protects us from predators, a source of light when we’re lost in the dark, keeps us warm from the cold and vegetation that got burned by fire provides useful nutrients for the soil.
5. Space- Space exploration allows us to discover new materials and objects that may be useful in our life or for the upcoming inventions of the future and it also expands technology .
Without any one of these elements, living species will struggle and deteriorate. They will not be able to increase in population meaning that the species will disappear in the next generation thus becoming extinct. All living things will die from hunger, diseases, cold and lack of natural resources .
Answer:
The oldest rocks of the oceanic crust are found in deep ocean trenches far away from active mid-ocean ridges.
Explanation:
Beginning in the late 1940s, oceanic expeditions continued to map the Atlantic ocean floor using new equipment and collecting thousands of rock samples. These works made it possible to map a gigantic system of submarine mountain ranges, called meso-ocean ridges. By perfecting the method of dating rocks, scientists have been able to determine the true age of seabed rocks. They found that the closer to the mid-ocean ridge the rocks were much younger than imagined, while rocks close to the continents were increasingly older, thus corroborating the Continental Drift.
Answer:
The statement that is NOT true about Guinea worm disease is It is a noncommunicable disease
Explanation:
The Guinea worm disease is a disease that infects people who drink water contaminated with copepods carrying worm larvae. It can be prevented by filtering drinking water and stopping infected people from entering shared water sources. People with blisters and visible worm wounds/ infections could potentially release the female worm or a liquid which in contact with water release more larvae.
