Answer:
This occurs due to the convergence of different air masses with different temperatures, density, and humidity. The turbulent conditions are produced, and cyclonic rain occurs along the fronts of the cyclone. The layer separating them is known as a front. The front has two parts – the warm front and the cold front.
At the warm front, the lighter warm air that is less dense usually forced to rise over denser cold air and thereby leading to cyclonic rain. A variety of clouds get formed, and they generally lead to moderate to heavy rainfall.
Causes for Occurrence of Frontal Rainfall
A tropical warm air mass comes in contact with a cold air mass of polar region. The less-dense, lighter warm air is then forced to rise over the denser, cold air.
It causes warm air to become cold. As the warm air is forced to rise further, it condenses to form the stratus cloud.
After becoming saturated, the stratus cloud begins to precipitate.
Frontal or cyclonic rain falls gradually for a few hours which can also extend up to a few days.
It is prevalent in Britain and Ireland, which is associated with the movement of depressions over the country. In north-west Europe, warm oceanic air and cold continental air converge to produce heavy rainfall in adjacent areas.

Answer:
Explanation:
The three main types of volcanoes are as follows:
1. Composite volcanoes: These are also called as strato volcanoes. These are steep and formed by the layers of ashes and lava. The eruption from these volcanoes is in the form of pyroclastic flow. The pyroclastic flow is in the form of superheated mixture which consists of rock dust, ash, and hot steam. These volcanoes can rise above the 8000 feet. These are found in the destructive plate margins. Example of these volcanoes include the Mount Fuji in Japan.
2. Shield Volcanoes: These volcanoes are low and they have gentle sloping sides. These are formed by the layers of lava. Their eruption of lava is non-explosive. These produces the fast flowing fluids that can flow to many miles. These can destroy the nearby surrounding regions can cause injury and even death. These volcanoes are found in the region of constructive boundaries and also at the volcanic hotspots. The examples of shield volcanoes include the Maunaloa on Hawaii.
3. Dome volcanoes: These are also called as acid lava cones as these emit acid which is much thicker than that of the lava. These have steeper sides as compared to the shield volcanoes. The lava is thick and sticky as a result of this it cannot flow to far region and it cools and solidifies. The example of dome volcanoes include the Puy de Dome of Auvergne, France.
