When two air masses with different temperatures or humidity levels meet, they do not immediately mix or blend. Instead a line or boundary forms between them. This boundary is called a......<u>front</u>
Explanation:
Due to the different properties, especially temperatures. The less-dense air mass tends to rise while the denser tends to dive at the front causing turbulence. There are four main types of fronts;
- Cold front – bring rainfall and thunderstorms
- warm front – associated with less intense weather
- Occluded front – when a warm air mass is in between two cool air masses
- Stationary front - can be warm or cold but barely moves
Answer:
The six essential elements are The World in Spatial Terms, Places and Regions, Physical Systems, Human Systems, Environment and Society, and The Uses of Geography.
Answer:
Drought is a dangerous condition which decreases the quality of life. It is termed as a natural disaster with harmful effects. A drought usually occurs when a region faces a shortage of water. This is mainly due to lesser rainfalls. In addition, droughts have proven to be fatal for mankind and wildlife as well.
Moreover, drought is the most dangerous for a farmer. As they do not have an ample supply of water, their crops dry out. This becomes a reason for worry as it is their sole income. Furthermore, drought also leads to various other problems for the environment and mankind.
Causes of Drought
Drought is caused due to various reasons. One of the main reasons is deforestation. When there will be no trees, the water on land will evaporate at a faster rate. Similarly, it lessens the soil capacity to hold water resulting in evaporation.
Moreover, lesser trees also mean lesser rainfall which eventually leads to drought.
Furthermore, as the climate is changing, the water bodies are drying up. This results in a lower flow of surface water. Therefore, when the rivers and lakes will dry out, how will the people get water? In addition, global warming is a major cause of this. The greenhouse gas emitted causes the earth’s temperature to rise. Thus, it results in higher evaporation rates.
Subsequently, excessive irrigation is also a great cause of droughts. When we use water irresponsibly, the surface water dries up. As it does not get ample time to replenish, it causes drought.
