Seismic waves help scientists understand Earth's layers by:

  • Scientists can observe how seismic waves change speeds when passing through different layers.
  • Scientists can observe which seismic waves cannot pass through certain layers.

<h3>What are Seismic waves?</h3>

These are waves which are generated as a result of the movement of

materials in the earth. They change speed as a result of the collision with

materials in the earth and know the types of material present as a result of

some types not being able to pass through certain medium.

Glia that provide myelin for neurons in the brain are called ________.
kati45 [8]

Answer:

oligodendrocytes

Explanation:

Glial cells are part of the nervous system. These are helper cells that support the function of the central nervous system (CNS) and can be called oligodendrocytes when they supply myelin to neurons.  These cells are responsible for producing the myelin sheath have the function of electrical insulator for CNS neurons. They have extensions that wrap around the axons, producing the myelin sheath.

It is estimated that there are 10 glia cells in the CNS for each neuron, but because of their small size, they occupy half the volume of nervous tissue. They differ in form and function and they are: oligodendrocytes, astrocytes, Schwann cells, ependymal cells, and microglia.

The picture is a scientific model which is used to explain the concept of the water cycle by means of pictures and descriptions.

<h3>What is a scientific model?</h3>

A scientific model is a representation which may be in form of pictures, illustrations, objects, or ideas which are used to explain a particular concept by scientists.

Scientific models are usually employed to explain either difficult to understand concepts or scarcely observable phenomena in order to enrich the knowledge and comprehension of others.

The given illustration is an example of a scientific model. It is used to explain the concept of the water cycle. By means of pictures and descriptions, the various processes of the water cycle can be fully comprehended.

Also, by means of a cyclical illustration, the model helps to explain that the water cycle is a continuous repetitive process.

In conclusion, scientific models may be in form of pictures, illustrations or objects.
