Answer:
1) Seven tectonic plates can be identified in the earth today.
2) The old sea floor sinks back into the earth to be recycled at the subduction zone.
3) The world's last supercontinent is known as Pangaea.
4) Pangaea began breaking up approximately 175 million years ago.

B.the area nearest to the Earth's crust
C.the area in-between the Earth's crust and core
D.the area nearest to the Earth's core
The area of the Earth'smantle that is the densest is the area nearest to the Earth's core. The correct option is D.
The earth is divided into three layers: the crust, the mantle, and the core. This is the earth's outer layer, and it is composed primarily of solid rock, primarily basalt and granite.
Oceaniccrust and continental crust are the two types of crust. The oceanic crust is denser and thinner, and it is mostly made up of basalt.
The five Earth systems (geosphere, biosphere, cryosphere, hydrosphere, and atmosphere) interact to create the environments we know.
The core is the earth's densestlayer, with a density ranging from 9.5 to 14.5g/cm3.
The Core is divided into two layers: the inner core and the outer core. The interior core is solid, while the exterior core is liquid (or semi-liquid).
Thus, the correct option is D.

Answer:
True
Explanation:
As per the gravitational law, the gravitational force (F) can be expressed as
------------- (1)
where,
Gravitational force
Gravitational constant
Mass of the Earth
Mass of the object
Distance between Earth and object
Also, the force due to gravity,
------------- (2)
where,
Gravitational force
Acceleration due to gravity
Mass of the object
Deducing both the equations
From the above equation it is clear that the acceleration due to gravity is independent of the mass of the object.
