The correct answer is - Olmec.
The Olmec civilization was existing in the period between 1,200 BC up until 400 BC. This civilization developed in Mexico, more specifically in the south-central lowlands of the country. The Olmec were a very advanced civilization for their time, and they are considered as the civilization that set the basis for all the others civilizations in Mesoamerica, like the more ''famous'' Maya and Aztec civilizations. The trademark of the Olmec is the big stone heads, about which there's lot of debates about their purpose and means.

4) Polaris
Stars emit light with energy generated by nuclear fusion, think of the Sun as an example. Polaris is a star, it's the brightest star in the little bear constellation, and therefore the correct answer.
Answer:
At convergent point of plate boundaries, sedimentary rock that is present at ocean floor is pushed down into mantle. Due to the continuous movement of rock into the mantle increase the crust the temperature. Thus after continuous rise of temperature, crust melts down and eventually rise to surface of earth in the form of volcanic eruption. and after cools down gives rise to formation of igneous rock.
Explanation:
Process of igneous rock is given below

There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water.
