The mantle — a 2,900 km thick layer of solid rock sandwiched between the Earth’s upper crust and lower core.
The mantle makes up the largest part of Earth.
  • The mantle’s viscous properties govern convection — the transfer of heat between areas of different temperatures. This enables plate tectonics.
Mantle convection results in the transport of rocks and heat.
The viscosity of the rocks in the transition zone between the upper and the lower mantle determines whether a plate sinks below another one (subduction) through it.
  • Statement 2 is incorrect.
  • The use of burnt bricks in the Harappan cities is remarkable because in the contemporary buildings of Egypt dried bricks were primarily used. We find the use of baked bricks in contemporary Mesopotamia, but they were used to a much larger extent in the Harappan cities.
  • The Indus people produced wheat, barley, rai, peas, and the like. Two types of wheat and barley were grown. A substantial quantity of barley was discovered at Banawali. In addition, sesamum and mustard were grown.
  • Although the Harappans practised agriculture, animals were raised on a large scale. Oxen, buffaloes, goats, sheep, and pigs were domesticated. Humped bulls were favoured by the Harappans. There is evidence of dogs and cats from the outset, and asses and camels were bred. Elephants were well known to the Harappans, who were also acquainted with the rhinoceros.

's crust and core.
The mantle is made up of mostly solid rock, but it can also contain pockets of molten rock or magma.
The mantle is responsible for the movement of tectonic plates and the formation of volcanoes and earthquakes.
The mantle extends from the crust to about 2,900 kilometers (1,800 miles) deep into the Earth.
The temperature and pressure increase with depth in the mantle.
The uppermost part of the mantle is known as the asthenosphere, which is partially molten and allows for the movement of tectonic plates.
Overall, the mantle plays a crucial role in shaping the Earth's surface and geological activity.
