How was Earth’s crust formed?

Answer 17

Earth is one of the only planets in the solar system on which life has evolved. Earth is said to have formed atleast 4.5 billion years ago. The temperature was so high that the Earth was a white hot mass of melted rock. It witnessed frequent volcanic eruptions. Many number of comets and meteorites collided with earth in its early evolution. One such large collision have caused the Earth’s tilt and formation of moon. The earth remained in the molten state for many million years and then began to cool. The volcanic activities also reduced considerably. The gradual cooling of the earth made the outer side to become solid , which is called the Earth’s crust

Question 18

How was food and shelter responsible for human evolution?

Answer 18

Hominoids- the hominoids lived on trees. The trees provided protection from predators. The hominoids were food gatherers. They procured food by gathering seeds, nuts, fruits, berries, tubers etc. they were not meat eaters.

Hominids- hominoids began to adapt to land . The change in climate or ice age reduced the forests and expanded the grasslands, plains and deserts. They were forced to come on to land to procure food. Initially they came on land for brief periods of time which gradually began to grow into longer periods. Then they adapted to land dwelling. The hominids began to use caves and extended stone boulder as shelter. These shelters on land provided them with considerable safety from predators and from rain, wind and the sun. The Neanderthal man was the early cave dwellers the shortage of food made them scavenge for food.
Hominines- and the archiac human species began planned hunting and fishing to the already existing gathering, foraging and scavenging techniques. The earliest evidences of planned hunting and butchery of large animals is traced in two sites
1) boxograve in England about 500,000 years ago
2) schoningen in Germany about 400,000 years ago
Planned hunting required developing tools and cooperation from fellow beings as the animals they hunted were stronger, larger and faster
