Slide 1: New Interchange Level 4 Unit 14: The biggest and the best! Slide 2: Grand Canyon The Grand Canyon is a steep-sided gorge carved by the Colorado River in the U.S. state of Arizona, and parts of Nevada. The canyon is 277 miles (446 km) long, ranges in width from 4 to 18 miles (6.4 to 29 km) and attains a depth of more than a mile (1.6 km). Slide 3: ANGEL FALLS Angel Falls (indigenous name: Kerepakupai merú) is the world's highest free-falling waterfall at 979 m (3,212 ft), with a clear drop of 807 m (2,647 ft). It is located in the Canaima National Park, in the Gran Sabana region of Bolivar State, Venezuela Slide 4: OKEFENOKEE The largest swamp in North America The Okefenokee Swamp covers roughly 700 square miles and is located in the southeastern corner of Georgia. Slide 5: The Zillertal branches off from the Inntal near Jenbach, about 40km northeast of Innsbruck, running mostly in a north-south direction. The Zillertal Slide 6: LAKE SUPERIOR The largest lake in the United States is Lake Superior, one of the Great Lakes, located on the United States / Canada border. It is largest in both surface area 31,700 square miles (82,103 square kilometers) and in volume of water 2904 cubic miles (12,100 cubic kilometers Slide 7: Mount Roraima It is the highest mountain in Guyana, but Venezuela and Brazil have higher mountains. The triple border point on the summit is at 5°12'08N, 60°44'07W. With a peak at 2,810 metres (9,219 feet), the mountain is the highest of Venezuela's distinctive table-top mountains, known as tepuis. Slide 8: Missouri River The longest river in the United States of America. The Missouri begins at the confluence of the Madison, Jefferson, and Gallatin rivers in Montana, and flows through its valley south and east into the Mississippi north of St. Louis, Missouri. At 2,540 miles (4,090 km) in length, it drains about one-sixth of the North American continent. Slide 9: BRACKISH The Baltic Sea is a brackish inland sea located in Northern Europe, from 53°N to 66°N latitude and from 20°E to 26°E longitude. It is bounded by the Scandinavian Peninsula, the mainland of Europe, and the Danish islands Slide 10: Malvern Hills The Malvern Hills are a famous beauty spot, with scenic views over both Herefordshire and Worcestershire. The Hills run north/south for about 13 km (eight miles), in between Great Malvern and the village of Colwall, and overlook the River Severn valley to the east, with the Cotswolds beyond. The highest point of the hills is the Worcestershire Beacon at 425 metres (1395 ft) above sea level (OS Grid reference SO768452), though they give the impression of looking considerably higher. Slide 11: Beresford Pass occurs on the south side of the Barrier and has a very narrow strip 1-200 yards wide. The Red Hills are the most colourful and geologically interesting range in New Zealand and one of the more unusual world wide. They are mainly formed of a peridotite A dunite consists mainly of the mineral olivine (Mg,Fe)SiO4) with accessory chromite and spinel. Sometimes harzburgite containing minor orthopyroxne and a little gabbro and anorthosite may be found. Because of the high iron content, the hills weather a deep red, brown and orange from the limonite formed. Being deficient in Ca, Na, K, P, Bo and other essential minerals, no vegetation grows on them, but they are not "toxic" as often reported, merely deficient in essential elements. The Red Hill Range Slide 12: The Arenal Volcano is one of the biggest tourist attractions in Costa Rica, and La Fortuna, the most popular destination to see the rumbling giant The Arenal Volcano is the only volcano in Costa Rica constantly active since it woke up after 400 years with the big 1968 eruption producing huge ash columns, explosions & glowing red lava almost every day. It is considered one of the ten most active volcanoes in the world. Arenal volcano Slide 13: The pacific ocean The Pacific Ocean is the largest of the Earth's oceanic divisions. Its name is derived from the Latin name Mare Pacificum, "peaceful sea", bestowed upon it by the Portuguese explorer Ferdinand Magellan. It extends from the Arctic in the north to Antarctica in the south, bounded by Asia and Australia on the west and the Americas on the east. At 169.2 million square kilometers (65.3 million square miles) in area, this largest division of the World Ocean – and, in turn, the hydrosphere – covers about 46% of the Earth's water surface and about 32% of its total surface area, making it larger than all of the Earth's land area combined.The equator subdivides it into the North Pacific Ocean and South Pacific Ocean. The Mariana Trench in the western North Pacific is the deepest point in the Pacific and in the world, reaching a depth of 10,911 metres (35,798 ft). Slide 14: The majority of deserts are in the Arabian Peninsula, Australia, The Americas, North and South Africa, India and Pakistan. The largest desert is the Sahara, in North Africa, and is about 3,500,000 square miles. Deserts are characterized by extreme heat and dryness, very hot in the daytime and chilly or even cold at night. Deserts represent one-fifth (20%) of the land surface of the world. The Sahara Desert Slide 15: The Portland park The park covers more than 5,100 acres (21 km²)of mostly second-growth forest with a few patches of old growth and is threaded by more than 70 miles (110 km) of recreational trails. Forest Park stretches for more than 8 miles (13 km) Slide 16: The West Siberian Plain The West Siberian Plain is a large plain that occupies the western portion of Siberia and Russia. It has been described as the world's largest unbroken lowland—more than 50 percent is less than 330 feet (101 m) above sea level and covers an area of about 2.6–2.7 million km² which is about one third of Siberia, extending from north to south for 2,400 km, from the Arctic Ocean to the foothills of the Altay Mountains, and from west to east for 1,900 km from the Yenisei River to the Ural Mountains. Slide 17:  Yosemite Falls is the highest measured waterfall in North America. Located in Yosemite National Park in the Sierra Nevada mountains of California, it is a major attraction in the park, especially in late spring when the water flow is at its peak. The total 2425-foot (739-m) distance from the top of the upper falls to the base of the lower falls qualifies Yosemite Falls as the 6th highest waterfall in the world (with the recent discovery of Gocta Cataracts it presently appears on some lists as the seventh). Although often referred to as a "two-stage drop", the falls actually consist of three sections: Yosemite Falls
