Answer:
Arctic is degrading fast while antarctica is degrading slowly both by air and water.
Explanation:
- Its true that most of the arctic and the Antarctic ice sheets have melted and the earth surges steadily towards the dangerous wrath of the planet, various reports have given proof that the arctic ice or that of the north pole melting fast at an alarming rate as the altitudinal conditions and the impacts of the climate changes are more profound in this region.
- With the rise of temperature of more than 1.8° F, in the past decades, the temperature of this region the current rate of the greenhouse emission has destroyed about 90% of the ice that is left. And is projected to a 3.7° F rise as the threshold of the impact of man activities.
- <u>Antarctica, on the other hand, is not fast as arctic but thew studies have shown that is somewhat similar to average global warming. The antarctic absorbing up the heat from the southern ocean water bodies. Also in the past years, the invasion of species and the uneven cooling has led to 2 °C warming of the continent.</u>
The basic theory of plate tectonics is that along seafloor spreading zones, the continents are separating from one another. As they spread apart, magma comes to the surface and becomes new continental crust. As the tectonic plates move away from spreading zones, they collide with one another.
Answer:
The true statement is - Sympatric speciation only occurs in areas where there is local variation in environmental resources
Explanation:
- Sympatric speciation means the evolution of new species from an ancestor species which are occupying in the same area and no geographical barrier takes place.
- Overlapping of ranges takes place to the organism and old and new species are living i the same geographical region.
- A dam diving a fish population could lead to allopatric speciation where geographical barrier causes formation of new species which are completely different from their ancestor species.
I think its c because coal isnt considered a mineral/rock because it is organic(?)
