Answer:
Fossil fuels are carbon-based energy sources like coal, oil and natural gas created from decayed plants and sea creatures that accumulated in the oceans. A biofuel is any fuel that's made from plant materials
Explanation:
Explanation:
The rainforests typically have high biodiversity i.e it has large covers of flora and fauna.
The tropical rainforests are considered to be the oldest biome on earth and that is why they have high biodiversity also there fact is the geographical area of these rainforests are pretty enormous and widespread across the globe.
the tropical rainforests provides equitable climate i.e good amount of rainfall and warm temperature which is a optimum conditions for plants and animal species to survive and also features the best conditions for regular food supplies and growth in natural biodiversity.
many different sources of food and types of shelters are also available in the tropical rainforest, fulfilling the conditions for a vast varieties in natural biodiversity. another important factor that the situations arises in this areas makes way for the new species such as natural disturbance and presence of mountain regions makes home for the refugee species to survive and live.
so these are the reasons why rainforests are typically so biodiversed.
plants and animals ecology in the rainforest has not been in the perfect condition which use to be some decades back it is worsening with time and is a matter of concern.
Tropical rainforests loss is a major environment concern today as because of global climate change has caused major deforestation in the tropical areas. people's influence on the rainforest is also a big problem to watch for.they have started clearing these huge forest cover for wood for furniture and for agriculture and cattle grazing. apart from these issues extinction of species due to global warming has also taken place.
Increase in green house gases and change in natural water cycle have started effecting the natural environment of these rainforests and so tropical rainforests today is big environment concern, as plants and animal's ecology has been disturbed.and losing of natural habitat.
Answer:
The Printing Press
Explanation:
In the 15th century, an invention called the printing press enabled people to share knowledge more quickly and widely. Civilization never looked back. Knowledge is power, as the saying goes, and the invention of the mechanical movable type printing press helped disseminate knowledge wider and faster than ever before.
Answer:
geomagnetic field.
Explanation:
The earth magnetic field can be likened to a bar magnet with a North and South pole. It originates from the movement of molten iron and nickel in the outer core.
At every point in time, the magnetic field orientation can change. We must note that the magnetic north lies close to that of geographic north axis of the earth.
Around the mid-oceanic ridges, new materials are brought to the surface. These new materials can contain magnetic minerals such as haematite which are capable of being magnetized as a result of the prevalent magnetic field of the earth. As different materials are brought up, the magnetic minerals preserves the details of the magnetic field at that point in time. Using this information can know the orientation of the magnetic field at any point in time if the magnetic history chart of the earth is constructed. Oceanic ridges becomes older as they move away from the divergent margins.
