Answer:People have made art for thousands of years. Some of the earliest art comes from the Stone Age, a time period during which early humans first made and used simple stone tools. Scholars divide the Stone Age into three spans of time: the Paleolithic (the word literally means old stone age), which runs from 2,500,000 to 10,000 BC; the Mesolithic, from 10,000 - 4000 BC; and the Neolithic, from 4000 - 2000 BC. In each period, the tools became a little more complex. The art from this time is also sometimes also called prehistoric art, because it was made before recorded history.
The people who created Stone Age art relied on natural materials they found in their environment. They used all types of stone and also mammoth ivory, animal bones and antler out of which they carved small figurines. They painted on cave walls, using clay ochres and iron oxide for yellows and reds, and manganese oxide and charcoal (burnt wood) for black. Think of the first ancient painters. How did they figure out what substances left the best mark? Stone Age art is an interesting glimpse into the ingenuity of early humans.

<span>Igneous
rocks are formed through the lava and magma cools then crystallizes.
Igneous rocks can also be form without going through crystallization. The occurrence
of igneous rocks may undergo with 2 different process; the intrusive or
plutonic, or the extrusive or volcanic. Intrusive igneous rocks are from magma
that cools and became solid inside the crust of the earth surrounded with
country rocks. While the extrusive igneous rocks are those rocks that formed in
the crust surface as a result of melting of rocks inside the mantle.</span>
