BartSMP [9]3 years ago
4 0

Answer:

The scientist is determining the relative age of the rock and the method is known as relative dating of rocks.

Explanation:

The relative dating method is based on the fact that more older the rock layers, the more it would be deeper. The overlying layer of rock will be located in less deeper location, henceforth it would be less older rock layer. This method is mainly used by the scientists, for determining the age of the rocks or fossils embedded in it, before any absolute dating method like radioisotope dating of rocks is discovered.

Zolol [24]

Answer:

In quiet breathing inspiration involves muscular contractions and expiration is passive.

Explanation:

Respiration process involves two different stages, inspiration - inhalation- and expiration - exhalation-.

During inspiration, the diaphragm <u>contracts</u> and goes down, while intercostal muscles also <u>contract</u> and go up. These actions enhance the size of the thoracic box and <u>reduce internal pressure</u>. As a result, air flows in and fills the lungs.

During expiration, the <u>diaphragm relaxes</u> and the volume of the thoracic box diminishes, which causes the <u>pressure inside to increase</u>. In consequence, the lungs contract and the air is expulsed outside.
