What physical forces shape the two types of Caribbean islands?
What physical processes have shaped the landforms of Central America and the Caribbean? Mountains formed in Central America and Lesser Antilles by plate collisions (subduction). Volcanoes formed islands and mountains. Coral reefs uplifted by tectonic collisions became islands.
What major landform has been created by the interaction of the Eurasian and African plates?
the Atlas Mountains Movements between the African and Eurasian plates created the Atlas Mountains. The Atlas Mountains are Africa's longest mountain range.
How has the Nile River been the lifeblood of North Africa?
How has the Nile River been the lifeblood of North Africa? It supports the growth of plant and animal life, and human settlement and development.
How have dams along the Nile River affected the natural landscape and soils of the region alluvial soil?
The dams were built to control the river's flow and reduce flooding. Dams were also built to provide year-round irrigation and hydroelectric power in Egypt. However, without the annual deposition of new alluvial material, soil fertility diminishes and requires the use of fertilizers.
How was the Caribbean formed?
The largest group of the Caribbean Islands were formed by volcanoes erupting from the ocean floor while many other islands broke off the North American continent millions of years ago. Several of the smaller islands are a result of coral buildup peeking through the ocean's surface.
What physical features do Central America and the Caribbean have in common?
Physical Features Sandy beaches, volcanic mountains, rain forests, clear blue water—these are images many people have of Central America and the Caribbean islands. This region's physical geography is beautiful. This beauty is one of the region's greatest resources.
What physical forces cause the creation of wadis quizlet?
Interpreting What physical forces cause the creation of wadis? braided stream patterns because of the deficiency of water and the abundance of sediments.
What physical processes are responsible for the creation of the rift valleys of eastern Africa?
Millions of years ago, the Arabian Peninsula was connected to Africa. Seafloor spreading caused the Arabian and African plates to rift apart. The Indian Ocean flooded the rift valley between the continents, creating the Red Sea.
How was river Nile formed?
A new study finds evidence that supports the latter theory: The Nile River may have emerged around 30 million years ago, driven by the motion of Earth's mantle — the thick layer of rock between the Earth's core and crust, a group of researchers reported on Nov. 11 in the journal Nature Geoscience (opens in new tab).
How have physical features affected the human geography of the eastern Mediterranean?
How have physical features affected the human geography of the Eastern Mediterranean? Mountains and deserts impact areas of settlement in the eastern Mediterranean. the poor soil in the Anti Lebanon mountains and the rocky terrain in the Galilee area are unsuitable for agriculture and have low population.
What caused the Nile river to flood?
The River Nile flooded every year between June and September, in a season the Egyptians called akhet – the inundation. Why did the Nile Flood? Melting snow and heavy summer rain in the Ethiopian Mountains sent a torrent of water causing the banks of the River Nile in Egypt to overflow on the flat desert land.
What causes the Nile to flood?
The flooding of the Nile is the result of the yearly monsoon between May and August causing enormous precipitations on the Ethiopian Highlands whose summits reach heights of up to 4550 m (14,928 ft).
What is the main tectonic process in the Caribbean?
The Caribbean plate is being pushed eastward due to a thick section of the South American plate called a "cratonic keel." This section of crust is three times thicker than its surroundings. Meanwhile, part of the South American plate is being pushed beneath the Caribbean plate, a process called subduction.
What type of plate boundary is Caribbean?
The South American plate lies mostly to the South. This is a transform plate boundary, and the Cocos plate lies to the west and this is a converging plate boundary. The northern boundary of the Caribbean plate with the North American plate is a transform plate boundary, as seen in the image above.
How was Central America formed?
Central America was formed more than 3 million years ago, as part of the Isthmus of Panama, when its portion of land connected each side of water. In the Pre-Columbian era, the northern areas of Central America were inhabited by the indigenous peoples of Mesoamerica.
What is the main physical feature of Central America?
Central America is a land bridge connecting the North and South American continents, with the Pacific Ocean to its west and the Caribbean Sea to its east. A central mountain chain dominates the interior from Mexico to Panama. The coastal plains of Central America have tropical and humid type A climates.
What geographical characteristics define the Negev desert?
The Negev is a rocky desert. It is a melange of brown, rocky, dusty mountains interrupted by wadis (dry riverbeds that bloom briefly after rain) and deep craters. It can be split into five different ecological regions: northern, western and central Negev, the high plateau and the Arabah Valley.
Why does Caribbean culture reflect a variety of different influences?
Why does Caribbean culture reflect A variety of different influences ? Because different types of people live there. What are the main economic activities in the Caribbean islands?
What type of plate movement caused the rift valley?
Areas where plates are colliding form convergent boundaries, and areas where plates are expanding create divergent boundaries. Rift valleys are formed by divergent boundaries that involve continental plates.
How are valleys formed by plate tectonics?
The valleys form when continental crust is pulling apart allowing the land to drop down between parallel faults. These valleys also form when oceanic plates are moving apart forming a divergent boundary.
What is the true source of the river Nile?
Lake Victoria Beginning in the mid-1800s, Lake Victoria was largely accepted as the source of the White Nile. But generations of explorers continued to push farther into the heart of Africa to discover tributaries of Lake Victoria that would qualify as the Nile's “true” source.
How do geologists explain the formation of the Nile Valley?
Answer: The Geologists explain that the entire soil of the Nile valley is the creation of the river itself. It was brought down as the finest silt in its flood waters, from the highlands of Abyssina and from remote Africa. Egypt, in fact, was made by its river.
What are some of the impacts the physical geography of Europe has had on the development of Europe?
Europe's moderate climates and favorable relative location are supported by its access to the many rivers and seas. These advantageous developmental factors supported the development of the Industrial Revolution in Europe, which gave rise to highly technical and urban societies.
How does physical geography affect the Middle East?
Rivers allowing for productive agriculture were the key factor in the settling of cities. Mountain ranges kept cultures in separate areas, providing natural barriers to imperialist agendas. The rich, fertile soil of the Middle East led early civilizations to settle, domesticate plants and animals, and thrive.

Meanwhile, part of the South American plate is being pushed beneath the Caribbean plate, a process called subduction.
How was the Caribbean plate formed?
The Caribbean Plate began its eastward migration 80 million years ago (Ma) during the Late Cretaceous. This migration eventually resulted in a volcanic arc stretching from northwestern South America to the Yucatán Peninsula, today represented by the Aves Islands and the Lesser and Greater Antilles.
How did Central America get divided up?
It is sometimes referred to as the United States of Central America. Between 1838-1841, multiple civil wars broke the republic apart. Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua became sovereign nations. Panama, in the meanwhile, was part of a colony that extended into South America.
What is Central America made of?
What is Central America? Central America is the southernmost region of North America. It lies between Mexico and South America, and it includes the countries Panama, Costa Rica, Nicaragua, Honduras, El Salvador, Guatemala, and Belize.
