Scientists want to learn about life on Earth long ago, so they dig for fossils. A fossil is what is left from a living thing that died long ago. Most fossils are found in layers of rocks. Most form after a plant or an animal dies and is covered rapidly with dirt and sand.

Fossils can help scientist learn more about plants and animals from long ago. Using fossils, they can figure out how the organisms were composed. In the case of dinosaurs, it helped figure out their diets.

The skeletal part of the musculoskeletal system: helps the body to create heat. protects the organs of the body. produces facial
vovangra [49]
It protects the organs of the body. Think about this..... Your bones are arranged so that each organ is protected. Each bone is like a border so that your organs are not exposed. If you didn't have bone then, if you got hurt then your vital organs could get hurt. It doesn't eliminate wastes from the body because that's the excretory system. It doesn't produce facial expressions since that is the nervous system ( heat is also controlled by the nervous system).

Most metamorphic processes take place
natka813 [3]

Most metamorphic processes take place B. a few kilometers below Earth’s surface.

<h3>Further explanation </h3>

Metamorphism is the change of minerals or geologic texture in pre-existing rocks without the protolith melting into liquid magma. Metamorphism often occurs on two scales: contact and regional. Contact metamorphism occurs  locally in areas adjacent to igneous intrusions or in areas that are in contact with hot water known as hydrothermal fluids. Whereas regional metamorphism occurs over much larger areas such as rising mountain ranges, large igneous intrusions can form and warp overlying strata increasing the pressures above the intrusion. Regional metamorphism usually produces foliated rocks such as gneiss and schist.

There are other ways that metamorphic rocks can form,  Dynamic metamorphism. Dynamic Metamorphism also occurs because of mountain-building. The huge forces of heat and pressure cause the rocks to be bent, folded, crushed, flattened, and sheared.

Metamorphic rocks form when increased heat and pressure force physical changes in the crystalline structure of an existing rock. Under the right conditions, any type of rock can become a metamorphic rock including igneous rocks, sedimentary rocks, and even other metamorphic rocks. Therefore metamorphic processes result due to intense heat and high pressure below the Earth's surface.

Which explanations most likely the reason for the evolution of the larger brains and human?
zubka84 [21]

The reason is that of the significance of the brain in human existence. In biology, the traits that provide an advantage in the environment are preserved and improved upon.   Therefore, as humans continue to use their brains to influence their environment, as the society rewards those with higher intelligence (associated with bigger brains),the bigger brains will be favored by natural selection.
