Explanation:

Not the ocean, impossible to be in top of the core, not in the air

The modern model of the Plate Tectonic Theory suggests that the continents and the major tectonic plates drift slowly on the Earth's core. The Earth's surface is divided in the many layers.

What is the shape of Earth ?

The shape of the Earth is said be oval where the planet is little bent over the sides but seems round. The question seems to be controversial.

Earth's outer surface is the outer layer of the planet which is made up of many layers and this is called as lithosphere where the several plates glide over the surface.

The rocky surface of Earth made up of several layers glide over one another and make the surface a little uncomfortable. The gliding causes a movement of tectonic plates that leads to earthquake.

The gliding theory has many concepts related to it. The plates are acting like a hard plates in comparison to the Earth's plate.

Therefore the correct answer is the upper layer of the Earth's mantle.

Why is acid precipitation such a problem all around the world?

Answers

Acid rain is linked to both natural and man-made sources. Nitrogen oxides are formed through the extreme heating of air when a thunderstorm produces lightning. Also, sulfurous gases are discharged from erupted volcanoes and rotting vegetation. ... For this reason, acid rain is considered a global problem.

Acid rain can be very problematic, because many environments can’t handle the change to their ph levels. Wildlife such as forests and ponds have been greatly devastated by these means, which forces many animals out of their habitats. Acid precipitation can also have an effect on buildings and man-made structures, because of the materials they are built with. As an example, many medieval sculptures made out of sandstone have been detrimentally damaged from acidic rain. Not only can it hurt the environment, but also thwarts the acquisition of historical knowledge. Hope this helps!!

Gravity on Earth is 9.8 m/s2, and gravity on the Moon is 1.6 m/s2.

So, if the mass of an object on Earth is 40 kilograms, its mass on the Moon is____ kilograms and its weight on the Moon is _____newtons.

Answers

Answer:

Mass = 40 kg Weight = 64 N

Explanation:

Mass does not change. 40 kg on Earth = 40 kg on the moon = 40 kg on Saturn, etc.

Weight = Force = Mass*Acceleration

So, Weight = 40 kg * 1.6 M/s^2 = 64 newtons
