Answer: One of the major environmental concerns in South and Southeast Asia is pollution. Water pollution in the region is caused by industrial waste and untreated sewage. Industrial waste often travels downstream and affects the water supplies in cities and farms. Cities often dump sewage into rivers without treating and cleaning the water. The untreated water contains bacteria or parasites. People can become very sick when they drink the polluted water or use it to grow crops. People may end up with severe diseases or long-term health conditions. Air pollution is caused by slash-and-burn farming, fires, and airborne chemicals from vehicles and industries. The smoke and haze released into the air can travel hundreds of miles and affect entire regions. People can become ill when they breathe the air.

Answer:
E. hydrologic cycle
Explanation:
The transfer of water between the atmosphere, the oceans, and the continents is known as the hydrologic cycle which involves water moving from the surface most importantly from the oceans to the atmosphere, over the land and everywhere in between. In phases of water, the earth is a sealed system, so water is not joined or withdrawn from the earth, it is simply transformed, transported, and even recycled.
Since the hydrologic cycle has no start or end, you can dive in at any step. A great place to start is in the oceans, where most water of the earth is stored.
A common crescent-shaped dune with horns pointed downwind is called a barchan dune.
A barchan or barkhan dune is a crescent-shaped dune. Barchan ("BAR-kahn") dunes form in areas with only one wind direction, and little or no vegetation. If conditions were "perfect"—the landscape was flat, winds blew from only one direction, vegetation could not grow, and sand was available but limited —barchan dunes would dominate a sandscape. One of the commonest types of dunes, it occurs in sandy deserts all over the world. Barchans are mostly formed by the wind from one direction and appear convex. They are arc-shaped, significantly asymmetrical in cross-section, with a gradual slope towards the wind sand ridge, and made out of well-sorted sand.
