<u>Answer:</u>

Liquid in the thermometer expands and rises when it exposed to warm air.

<u>Explanation:</u>

The Thermometer can be used to measure the temperature of the air. When a thermometer is exposed to the atmosphere, the thermometer’s temperature tries to equalise the temperature of the surrounding air.

The state at which the temperature of the thermometer is equal to surrounding air temperature is called as Thermodynamic Equilibrium. To reach this state the liquid present inside the thermometer must either heat up or cool down.

So when a thermometer is exposed to warm or hot air, the liquid inside the thermometer(mercury) gets heated up. This heat causes the liquid to expand to reach the equilibrium state. Similarly, when the thermometer is exposed to cool air, the liquid condenses to match the outer temperature, thereby reaching the thermodynamic equilibrium.

This map uses red arrows to show the direction and magnitude of tectonic plate movement.
Fittoniya [83]

The correct answer is - b. African.

The African tectonic plate will move the most of all tectonic plates. It is moving into a northeastern direction, and it is pushing towards the western part of the Eurasian tectonic plate and it is squeezing the Arabian tectonic plate between itself and the Eurasian tectonic plate. Because of this movement, the African tectonic plate in a relatively small amount of time (geologically speaking) will merge with Europe, and since both of the plates are of same density a large mountain range will start to form because of the pressure between the two plates. Also, the Mediterranean Sea will be cut of from the Atlantic Ocean and it will dry out.

Why are the mountains thinly populated? Answer long in points . Please!​
RUDIKE [14]

Answer:

The main reason why mountains are rarely populated is because of the harsh climate that are dominating in those areas. On the other side, another important reason is that mountainous areas are not fertile enough and people are not able to grow crops. Lack of resources therefore is obliging people to move from the mountains to lower terrains.

Explanation:

Because of the mentioned reasons most of the people since the beginning of civilization were inhabiting river valleys and the areas that have better climate.

For example, Chinese civilization developed in the valley of Yangtze and Huang He and not Himalayas.
