Transcript of The way Angel Falls and many other waterfalls are formed is

The way Angel Falls and many other waterfalls are formed is when water rushes down steep hillsides and quickly erodes the rocks. The height and number of waterfalls along a stream or river depends upon the type of rocks that are being eroded by the water. Some types of rocks (shale, for example) wear away more easily than others (such as sandstone or limestone).As the river or stream wears away the weak rocks; they travel across the surface of stronger rocks. These more resistant rocks become the capstones to waterfalls and control how many vertical drops there is on each waterfall.

Angel Falls
Significance
Angel falls is mainly significant due to it being the highest waterfall in the world. The highest point of the falls reaches 979 meters, with water falling from a height of 807 meters. The height of the falls is so great that by the time it reaches the ground the tiny particles of water turn into fog. Angel falls is also a UNESCO world heritage site. The water fall was named after Jimmie Angel, a Us aviator, who was the first person to fly over the falls in the mid-twentieth century. After Jimmie angels death his ashes were scattered of the falls in 1960.
Due to Venezuela being close to the equator the weather varies very little throughout the year. The closest main city to angel falls is Canaima, as you can see above it is a very sub-tropical area. There are tremendous gusts of winds and spray that are created by the water crashing onto the rocks ad ito the cave.

The Pemon Indians call the mountains which hold the falls ‘Tepuis’. They believe that it is supposed to be where the gods live. As well as that, they believe that the sinkholes located in the mountains are supposed to be the cooking pots of the god of rain and thunder. The Angel Falls and Tepuis are a great deal of significance to the natives and affects many cultural aspects.
Angel falls is one of the seven natural wonders of the world so it makes it a major tourist attraction. The locals such as the Pemon Indians make a living by guiding tourists and running hotels. Angel Falls is in a very remote place so people can only reach there by boat or plane. The natives also make a living by operating these boats, which are usually canoes or small planes. The region is very lush and tropical which makes it easier for the locals to grow crops to make money.

Cultural significance and human impact
The tropical wildlife in the area includes monkeys, poison arrow frogs and hundreds of species of orchids. Mammals are usually hard to spot but include giant ant eaters, armadillos, porcupines, three- toed sloths, otters, jaguars, pumas, tapirs and capybaras. Dense jungles surround the falls. One third of the plants found here are found nowhere else on the planet.
Angel falls is a paradise of orchids. Orchids are grown by thousands and over three hundred species are found here. They grow by the waterfalls, by the rivers and even in rocky areas.

THREATS
There are no major threats to angel falls today, but in the past there were two main threats to Angel falls and its surrounding areas. The local people that inhabit this area (the penom) have been a threat due to the population rising quickly in the past 20 years. Which has bought a great demand on the parks natural resources. The tourism industry has been threat by hikers going off-trail and destroying the plants, the industry also continues to develop the park without planning before-hand.

Protecting angel falls for the future
Since the past, it has been observed that there have been vegetation changes and the air surrounding angel falls has become more humid. The area is really remote so there aren’t many threats to angel falls which needs protecting. As mentioned earlier, tourists trample the plants when they go off-trail. If this problem can be solved, lesser plants will be destroyed.
