Answer:

At the bottom of the sequence

Explanation:

According to the "principle of superposition of strata", the oldest rocks are formed at the bottom of sedimentary rock sequences.

The oldest rock layer would contain the the oldest fossil. Weathering, erosion, transportation and deposition would bring all sediments which includes rock materials and remains of living organisms to the basin where they would be lithified to form sedimentary rocks. This makes the oldest fossil to be at the bottom of the sequence. As time progresses, the fossil sequence would continue to accumulate and young upwards as the strata becomes relatively younger. Also, we know that fossils succeed one another in a definite manner.

This why relative dating of rocks can be possible.

Answer:

The correct answer is - Friction occurs irrespective of the state of the matter.

Explanation:

Friction is the force that takes place when there are two different surfaces slide or moves across one another and causes a resistance between surfaces. The friction always takes place opposite direction to the other surface direction of moving.

Pushing a book on a table, pulling a heavy cart on road all are examples of friction. The friction that occurs in liquids and gases is called fluid friction. Thus, the friction takes place irrespective of the state of the matter.
