An active volcano is a volcano that has had at least one eruption during the past 10,000 years.
Volcanic eruptions can affect the atmosphere and climate in the immediate vicinity of the volcano and also around the entire planet if the eruption is large enough. The main effect eruptions have on the weather near the volcano is producing large amounts of thunder, lightning and rain.
These effects are due to the large amounts of ash and debris that are released during the eruption, which attract water molecules from the atmosphere. This leads to the formation of clouds and eventually rain. Scientists are still not sure exactly what causes the increase in lightning, but the most accepted theory is that the ash separates into positively and negatively charged particles as it moves through the air.
Eruptions can also lead to large amounts of volcanic fog, as in the case of Hawaii. Volcanoes also release large amounts of sulfur dioxide, which leads to acid rain when it mixes with the water droplets in the atmosphere. This then has the effect of severely diminishing the overall air quality in the area.
Most eruptions are not powerful enough to send ash into the upper layer of the atmosphere, the stratosphere, which is why these effects normally only occur near the eruption. In most cases, the ash only goes as high as the troposphere, where it is washed away due to precipitation. However, larger eruptions that send particles into the stratosphere can lead to either a sudden cooling or warming of the Earth, depending on the size of the particles and how much heat they trap in or sunlight they block out.
Answer:
Explanation:
1. Kuwait, Israel, Iran, Lebanon
2.The world's demand of water is increasing because populations are increasing at a high rate and it will be used by farms, people for drinking water and agriculture.
3.The Middle East depends heavily for water supplies because the majority of their water comes from underground stores which are quickly draining. Therefore, people will most likely get less water per year.
4.Water is scarce because of the amount of water that is used by farmers for their crops.
Answer:
plate tectonics and climatic force.
Explanation:
- The Mojave desert is on the eastern side of the coast and is a rain shadow desert driest part of the North America found in southeastern California see in southeastern Nevada. And s border the great desert basin in the north and presence of the numerous ranges, basin lakes and pans are formed by the geologic crustal thinning that has created open valleys.
- <u>Similar the Atacama desert of the plateau region in south America contains of 1000 km of the lands and receive less rainfall, which accounts for a 105,000 km square. And the desert has a low relief similar to the giant uplifted traces and intermediate depression.</u>
