Answer 1

Answer:

Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing.

Answer 2

Answer:

1) The three layers of the earth are:

a) crust

b) Mantle

c) core

2) Any natural mass of mineral matter that makes up the earth's crust is called a rock.

3) Sedimentary Rocks

Igneous Rocks

Metamorphic Rocks

4) Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet.

5) The transformation of one type of rock into another, under certain conditions and in a cyclical manner is referred to as the rock cycle.

6) Uses of rocks are:

.It helps in making roads.

.It is used in the construction of houses and buildings.

.Small stones are used by children in different types of games.

.They are used in fertilisers.

7) Metamorphic rocks are the rocks that get formed under great heat and pressure. Igneous and sedimentary rocks, when subjected to heat and pressure, get transformed into metamorphic rocks.

8) Punjab is the 2nd largest province (area-wise) and has vast mineral potential in areas including coal, salt, iron ore, limestone, gypsum, and fire clay etc.

9) Since the temperature and pressure increase enormously as we go deeper and deeper inside the earth, we cannot go to the centre of the earth. ... Answer: Because of extreme heat and pressure, limestone undergoes a change in its form and turns into marble.So we cannot go to the centre of the earth.

Hope it helps you......
