Answer:
Crust, mantle and core are three layers of earth
Explanation:
- The earth consists of three basic layers crust (uppermost), mental (middle layer), and the core as (bottom-most). Due to the variation in the rates of energy that moves between the three layers i.e the earth waves knows as P, S, and L waves are known to occur at various points of time.
- These waves are called seismic waves and the P is called primary waves that can moves between the solids and liquids while the S layer moves to form solid objects and L long waves move.
- All these moves through various velocities and on reaching the earth's surface tell about the depth, magnitude, and intensity which helps the earth scientists to determine the interior.
Answer:
C) Photosynthetic bacteria, invertebrates, vertebrates, reptiles, amphibians, mammal.
Explanation:
- From looking at the above records of evolutionary life on earth the traces of living fossils and organisms that are evolved to the biogenic carbon signatures and the earliest known stromatolite fossils on earth the evidence of 3.7 billion year rocks taken from western Greenland.
- All show the occurrence of first life forms as photosynthetic bacteria and evolution of soil and oxygen in it took place then the invertebrates plat and animals appeared on land and oceans like the nematodes and arthropods, after which started to evolve like the vertebrates like the tetrapod the first fish with four limbs in 360 million years.
- After which reptiles and dinosaurs are the largest land reptiles evolved and then came the amphibian likes and then lead to the evolution of man and other mammals.
