Mantle convection - is when the plates move around the asthenosphere and the magma moves in circular patterns due to heat.
Movement of tectonic plates is related to convection currents in the earth's mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
The correct answer is - True.
<h3>The mangrove forests</h3>
The mangrove forests act like a natural barrier, a defense system if you will when it arrives to the negative effects of the hurricanes. These forests are located between the beach and the landmass.
They are very thick and resilient woods. Because of that, the mangrove forests tend to lower the speed of the winds, and split up the big waves, but also accumulate a lot of water in them.
All of those things combined manage to mitigate the storm harm in the places on the mainland, thus being a solid natural guardian.

Answer: c. Oxygen, silicon, and aluminium
Explanation:
The common elements in the Earth's crust in order of decreasing abundance are as follows:
Oxygen: Oxygen is the most abundant element on earth's crust. It makes up 46.6%. It exists as compound of the silicate minerals. It is used for industrial, commercial and medical purposes.
Silicon: Silicon is the second most common and abundant element on the earth crust. It makes up the concentration of 27.7%. It combines with the minerals of silica to form the silicate minerals. It is used for the purpose of ceramics, cosmetics, glass and other products.
Aluminium: Aluminium is the third most common and abundant element on the earth crust. It makes up the concentration of 8.1%. The aluminum exists in the form of aluminium oxide, potassium aluminium sulfate and aluminium hydroxide. It is used for the purpose of manufacture of rockets, machinery and automobiles.
Answer:
Non-conformity
Explanation:
An unconformity is a time gap or break in stratigraphic record of sedimentary rock layers. It is usually depicted by a period of non-deposition or erosion.
There are different types of unconformity:
>Disconformity
>Non-conformity
>Para-conformity
>Angular unconformity
Non-conformity is a type of unconformity marked by different rock types. The boundary between such rock types is an unconformity surface. For example, the boundary between an igneous rock that caps a sedimentary sequence is an unconformity.
