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:
Food security comprises of availability, access, utility and stabilization.
Explanation:
Food security is a measure to check the availability of food to individuals and their affordability being a prime factor. In other terms, it means that everyone has a sufficient amount of health food i.e it can be measured by calorie intake per person to lead healthy lives.
Food availability in developing countries is cause and an effect of several factors like poverty, status, political stability and infrastructure etc. Most of developing countries in the world have an undernourished or are malnourished population . Mostly in the African countries and the Asian countries like Afghanistan, Domenico republic of congo and Mexico which is dealing with acute food insecurity. As compared to developed countries like in Australia and North America have low food insecurity but they still face global water crisis, land degradation and impact of climate change along with food wastages.
Programs that help developing countries reach food security goals.
Use of genetically modified crops.
Boosting agricultural science and giving agricultural insurance.
Making food security gender-equal.
Reducing land-use changes.
Answer:
Due to the strong economic recession that the country is experiencing, which promotes the dismantling of refineries.
Explanation:
Venezuela has a very extensive complex of oil refineries, which is the most valuable Venezuelan product. However, due to the crisis in the oil sector, Venezuela has experienced a strong economic recession, which has caused a dismantling in refineries that has suffered a severe and constant degradation. This has increased the number of accidents with oil causing the contamination of various ecosystems. The government has not worked to solve these problems due to the lack of economic resources and the need to further degrade the oil industry.
