Answer:
The solar radiation is one of the main factors that shapes the climate all over the globe, so the climate differs with the less or more solar radiation it gets. The polar regions are cold, this is due to the fact that the solar radiation in here is very obscure, because the solar radiation falls at a very wide angle the heat is dispersed over larger area, thus the land gets very little warmth. The Equator, on the other hand, gets direct solar radiation, the sun light falls at a 90 degrees angle or close to it, so the radiation is more concentrated on a smaller area, thus the warming is bigger.

Where does old sea floor sink back into the earth to be recycled
The worlds last supercontinent is known as __________.
And last,
How many years ago did the supercontinent Pangea begin breaking up?
Answer clearly,
I will know if you used the internet or not

Will mark Brainliest!
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.

Answer:
V = 5.5 mL
Explanation:
The volume filled in the graduated cylinder is 12.7 mL
now when a stone is dropped into the cylinder then the volume of liquid is raised to final level of 18.2 mL
so as per the theory of given by Archimidies we can say that the volume of the object is exactly same as the volume displaced by the object
So here the volume displaced by the object is given as
so the volume of the object is given as
A adding batteries to the circuit
B removing its iron core
C increasing the current through the coil
D increasing the number of wire loops in the coil
Answer:
B. Removing its iron core
Explanation:
In an electromagnet role of its core is very important as it concentrate magnetic flux to make magnetic field more powerful. Generally core of electromagnet is made up of a ferromagnetic material or of a ferrimagnetic material such as iron. Adding batteries to the circuit and increasing the current through the coil and increasing loops in the coil will increase magnetic strength of an electromagnet.
Answer:
B. removing its iron core
Explanation:
The iron core inside of the wire coil increases the strength of an electromagnet. So removing the iron core would decrease the strength of an electromagnet.
