Compare and contrast up-lifted and fault-block mountains. Describe the mountains that form as a result of hot-spots in Earth's mantle. Features found at divergent boundaries include ocean ridges . ... Volcanoes that form over hot spots are often solitary and far from tectonic plate boundaries.
New species appear relatively quickly are associated with the theory of . (a) punctuated equilibrium. So option (a) is the correct answer.
A pattern of rapid evolutionary change followed by long periods of stagnation is a pattern explained by an interrupted equilibrium. Punctuation equilibrium states show that organisms do not change much as they appear in the fossil record.
Interrupted equilibrium predicts that many species evolutionary changes occur on short time scales associated with speciation events.
An intermittent equilibrium occurs as genetic variation passes more rapidly, increasing the rate of evolution and speciation. Tyrannosaurus fossils and mollusks species from the Turkana Basin are examples of intermittent equilibrium.

There are two distinct Cryogenian ice ages called Sturtian glaciation between 750 and 700 million years ago, followed by the Varanger (or Marinoan) glaciation, 660 to 635 million years ago which covered the earth ice. Also the Global sea level has fluctuated widely in the recent geologic past.
<u>Explanation:</u>
Cryosphere is the part of the earth’ surface where the land areas exits in the solid form when the warming temperature low. The snow and ice covers the 10% of the earth permanently in the ratio of 60% in northern hemisphere and less than in snow in southern hemisphere.
Its is formed due to lesser warm temperature. snow and the ice covered on the surface it store the fresh water under the floating ice, most of the fresh water is present in the two major ice sheets Antarctica and Greenland.
Melting ice does not cause any impact on sea because it was already floating on the sea surface. If the temperature become warm, its melt on the ocean itself.
Answer:
Gives more detailed look at cell OR shows cell ultrastructure (can be phrased either way)
Answer:
c2h4o
Explanation:
empirical formula is simplest whole number ratio of atoms in molecule
SINCE RATIO OF C,H O IS:
C : H : O
4: 8 :2
SIMPLEST RATIO ( DIVIDING BY 2)
2: 4: 1
C2H4O
