Answer:
The Hadean eon represents the time interval between 4.6 billion to 4 billion years back. It is marked by the initial formation of the earth , right from the time of gathering and accumulation of interstellar dust particles and gases, and there was frequent collision between the planetesimals of relatively larger in size. The core and the crust formed and started to become stable and also gradually led to the formation and expansion of the ocean and the earth's atmosphere.
This is how the earth gradually started to form and develop and took the shape during the time interval between 4.6 billion to 4.2 billion years old, and where the oldest rocks found on earth is dated from about 4.2 billion years in the past.
We select the symbol of '<' if we assume temporarily for 4x+3 12.
Assume temporarily for 4x+3 12, we select the symbol of '<' because the real equation is "4X+3>12" in which the symbol '>' is used. The symbol '>' is used to show the greater number and a smaller number. The pointed side shows that the number is smaller.
while on the other hand, the wider part shows that the number or value is greater than the other one so we can conclude that we select the symbol of '<' if we assume temporarily for 4x+3 12.

Answer:
I think twice the size of Olympic park
The statement underlying mantle layer is molten where convection currents cause the movement of the lithospheric plates explains the movement of these lithospheric plates.
<h3>What is tectonic plate movement? </h3>
The theory discusses how Earth's surface is composed out of rigid slabs of <em>rock</em> that are known as plates. These <u>large pieces </u>of plates under the Earth's surface are regarded as the lithosphere.
Therefore, convection currents that appear in the mantle lead to movements in the plates due to the flow of current to heat up the mantle.
