Answer:
A. The ice has a high albedo.
Explanation:
Albedo is a measure of ‘whiteness’ or reflectivity which is also the rate at which a surface is able to reflect a percentage of solar radiation it receives. White surfaces have a higher albedo which is why Arctic and Antarctic regions with lots of ice sheets have a high albedo. They play a big role in regulating global temperatures. The larger the ice sheet cover in the antarctic and arctic regions, the more they reflect solar radiation back to space hence keeping the temperatures on earth from rising considerably.
The Sahel is located in Africa. It is the region in Africa that transitions from the Sahara to the Sudanian Savanna. It stretches across in the region from the West of Africa to the East and includes parts of Senegal, Mauritania, Mali, Burkina Faso, Algeria, Niger, Nigeria, Chad, Sudan, South Sudan, Eritrea, CAR, Cameroon, and Ethiopia.
Most fo the hurricanes that affect the east coast of the United States originally form over the warm waters of the Atlantic Ocean in Summer (1). The warm waters of the Gulf Stream run along the east coast of the United States. This provides an environment which is conducive to the development of hurricanes. The basics of the formation of a hurricane are as follows. Winds start blowing in a circular motion. This causes hot, moist air to rise. Clouds are formed and the winds start blowing faster and faster. This forms a low-pressure zone. The surrounding high-pressure zones pull the hurricane towards them. As the hurricane moves, it either picks up speed or decreases its speed and intensity.
Answer:
"The asthenosphere (Ancient Greek: ἀσθενός [asthenos] meaning "without stength", and thus "weak", and σφαίρα [sphaira] meaning "sphere") is the highly viscous, mechanically weak and ductile region of the upper mantle of the Earth. ... In some regions the asthenosphere could extend as deep as 700 km (430 mi)."
