B. because the rock is formed and it goes younger as it grows the rock is still old on the inner layers but it adds new layers as it goes
Answer with Explanation:
The Miocene epoch was deeply characterized by<em> seasonal conditions</em>, such as having more colder winters in the northern areas.
In the <em>late Miocene</em>,<u> open vegetation system expanded. </u>These included<em> grasslands, woodlands and shrublands.</em> As a result, more primates inhabited the area. Several habitats became diverse from each other, thus allowing the species to adapt, including their locomotion. For example, the species who used to live on trees, turn towards living on land (terrestrial life). Certain animals also came about such as <em>pigs, giraffes, monkeys, etc.</em> Scavenging hominins also scattered. When it comes to hominins, a major type of locomotion evolved called "bipedalism." <u>This allowed the hominins to walk using the lower limbs (two feet).</u>

BENEFITS:
The Descriptive investigation is used to describe a natural system when nothing or very little is known about the system. Like observing a new specimen in the microscope and describing it by observing the specimen.
A comparative analysis is used to compare two or more variable in nature by collecting data like observing the different colors of the rocks. It provides the data to show the similarity and dissimilarity of the population.
The Experimental investigation is used where experiments are performed to test and answer the scientific questions. The advantage is that data can be used as evidence for future research.
LIMITATIONS:
<u>descriptive method of investigation
</u>
It cannot be used to correct variable or be used to determine causes and effect of the problem
<u>experimental method of investigation
</u>
It might create an artificial situation that do not always represent the real life situation
<u>comparative method of investigation
</u>
It is not easy to control other variables that might influence the study
<em>Ngl, I just copy and pasted these answers from another brainly question</em>
No. Deep Brain Stimulation blocks the defective electrical signals that can cause tremors and more movement symptoms.
