The indus valley civilization exist in what is now pakistan for about 1,000 years. true or false

It is true that Indus Valley Civilization exists in what is now 'Pakistan' for about '1000' years ago.

Explanation:

Commercial, religious, artistic connections have been existing then. The life was 'highly developed' city life with wells, bathrooms, drainage system etc. It is believed that the "drying of the River Saraswathi " was the main reason for the decline of the 'Indus Valley civilization'. Floods in the area was also another cause of concern. This made the economy no longer sustainable.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
