Befitting a lush, tropical island stranded in the middle of the ocean, Madeira's origins are shrouded in mystery and fanciful legend. Some claim that the archipelago is what remains of Plato's lost Atlantis, or part of a landmass that once fused the continents of Europe and America. The Portuguese Step Ashore: Recorded history of the volcanic archipelago begins in relatively recent times: 1418, just as the golden age of Portuguese discovery was erupting. Under the leadership of Henry the Navigator, caravels set out from the westernmost point of the Algarve, in southern Portugal, in search of foreign lands, fame, and wealth. João Gonçalves Zarco, sailing in the service of Prince Henry, made the first of many famous Portuguese discoveries, which would culminate a century later in Magellan's historic circumnavigation of the globe. Zarco happened upon a small volcanic archipelago 1,000 km from Lisbon. Perhaps Zarco knew precisely where he was heading, having learned of the existence of Madeira from a Castilian source. After all, the waters of the Canary Islands, only 445 km (275 miles) to the south, had occupied busy shipping lanes for very nearly a century, and Genovese maps from the mid-14th century depict both Madeira and Porto Santo. More likely, Zarco was heading for Guinea and storms forced him onto the beach of Porto Santo. If so, then he was extremely fortunate, for he managed to land on the only large, sandy beach for hundreds of miles around. Little wonder he subsequently named it Porto Santo (Holy Port). The following year Zarco returned to claim the larger island he had seen from Porto Santo, and with him went Tristão Vaz Teixeira and Bartolomeu Perestrelo. They officially became the first men to set foot on the heavily forested island, naming it Ilha da Madeira, "Island of Timber. " The Portuguese Crown, delighted with its first important discovery, immediately embarked on a program of colonization. Zarco and Teixeira were appointed co-go­vern­ors of Madeira, while Perestrelo was awarded Porto Santo.

When a stream or river slows down, it starts dropping its sediments. Larger sediments are dropped in steep areas. Some smaller sediments can still be carried by a slow moving stream or river. Smaller sediments are dropped as the slope becomes less steep. Alluvial Fans In arid regions, a mountain stream may flow onto flatter land. The stream comes to a stop rapidly. The deposits form an alluvial fan. Deposition also occurs when a stream or river empties into a large body of still water. In this case, a delta forms. A delta is shaped like a triangle. It spreads out into the body of water. 

Question: "What kind of shape does a river or stream emptying into the larger body of water sculpts the delta into?"

Response: "A triangle"
OPTIONS:
- no
- yes

A: yes
Problem: The highest point of a wave is the crest. The lowest point is the trough. The vertical distance between a crest and a trough is the height of the wave. Wave height is also called amplitude. The horizontal distance between two crests is the wavelength. Both amplitude and wavelength are measures of wave size. The size of an ocean wave depends on how fast, over how great a distance, and how long the wind blows. The greater each of these factors is, the bigger a wave will be. Some of the biggest waves occur with hurricanes. A hurricane is a storm that forms over the ocean. Its winds may blow more than 150 miles per hour! The winds also travel over long distances and may last for many days. 

Question: "How many times is wind mentioned?"

Answer: "More than Five"
