The answer is occluded front
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: Coffee (Café)
Explanation: Coffee is one of Costa Rica's biggest exports. (El café es una de las mayores exportaciones de Costa Rica.) It has become a very important part of the economy and aided in developing the country. (Se ha convertido en una parte muy importante de la economía y ha ayudado al desarrollo del país.) The coffee plantations have become major tourist attractions of the area. (Los cafetales se han convertido en las principales atracciones turísticas de la zona.)
Answer:
Explanation:
They are mostly soluble earth materials.
Dissolved loads are products of chemicals weathering.
Examples are dissolved soil minerals, dissolved rock minerals etc.
The products of chemical weathering of rocks dominate the dissolved loads in a stream. Most of these materials are in solution and can travel very far away unless they become precipitated.
To date, the majority of neandertal fossils have been found in Europe and western Asia.
There may have been little direct contact between neanderthals and modern humans over thousands of years. They might have contributed to the Neanderthals' impending extinction by preventing them from going back to the areas they liked best.
Around 40,000 years ago, all traces of Neanderthals vanished. The most recent Neanderthal fossils have been found at a few isolated locations in western Europe and the Near East, which was probably the last known location for this early human species.
