Answer:
- Cold currents
- Warm currents.
Step-by-step explanation:
Sea currents, in a simplified form, are the streams of water with common characteristics that move along the oceans. As temperature is one of the main factors related to this ocean water dynamics, it is used as a criterion for the classification of ocean currents. Thus, the currents are divided into warm and cold.
Warm currents: They come from the equatorial ranges of the planet, where the heat stroke is higher and the temperatures too. These characteristics make them more shallow and move faster than other currents. In them, the evaporation rate is higher, which causes the areas bathed by them to receive a greater amount of moisture. The main warm currents are the Guyana, Gulf of Mexico and Brazil currents.
Cold currents: Conversely, cold currents come from polar bands with high latitudes and are therefore colder. They move toward the Equator Line. Because cold substances are naturally denser, these currents tend to be deeper and move more slowly. Similarly, the evaporation rate is lower, making the surrounding areas receive less moisture and rainfall. The main cold currents are those of Humboldt, on the west coast of South America, and the Antarctic Circumpolar.
