Question

Река Ориноко и река Сан-Франциско протекают в субэкваториальном поясе, но Ориноко разливается летом, а Сан-Франциско - зимой. Почему так происходит? ПОМОГИТЕ ПОЖАЛУЙСТА

Answer 1

Эти реки разливаются тогда, когда приходит влажный экваториальный воздух (мЭВ) и приносит много осадков (сезон дождей). Ориноко в сев. субэкватор. поясе и мЭВ приходит летом (июнь-август). В южном субэкватор. поясе, где р. Сан-Франсиску, в это время сезон засухи. Через полгода (декабрь -февраль), когда там начнется лето, туда придет мЭВ и принесет дожди.
В юж. полушарии - декабрь -февраль - это лето!

Answer 2

The Orinoco River and the San Francisco River

The Orinoco River and the San Francisco River are both located in the equatorial region. However, they have different flooding patterns. The Orinoco River experiences flooding during the summer, while the San Francisco River experiences flooding during the winter.

The reason for this difference in flooding patterns is primarily influenced by the climate and rainfall patterns in their respective regions.

The Orinoco River: The Orinoco River is located in South America, primarily flowing through Venezuela and Colombia. It is one of the longest rivers in South America and is known for its extensive flooding during the summer months. The flooding is mainly caused by heavy rainfall in the region during this time. The summer months in the equatorial region are characterized by high temperatures and increased precipitation, leading to a higher volume of water flowing into the river. This excess water causes the river to overflow its banks and flood the surrounding areas.

The San Francisco River: The San Francisco River is located in Brazil and is the longest river entirely within Brazilian territory. Unlike the Orinoco River, the San Francisco River experiences flooding during the winter months. The winter season in the equatorial region is characterized by a decrease in rainfall. The reduced precipitation during this time leads to a lower volume of water flowing into the river. However, the river's capacity to hold water remains the same. As a result, the river's water level rises, causing flooding in the surrounding areas.

In summary, the different flooding patterns of the Orinoco River and the San Francisco River can be attributed to the variations in rainfall patterns and climate in their respective regions. The Orinoco River floods during the summer due to heavy rainfall, while the San Francisco River floods during the winter due to a decrease in rainfall.
