What is the term for long thin valleys that formed as a result of continental plates pulling apart?

long thin valleys that formed as a result of continental plates pulling apart. rift valleys. longest river in the world. nile.

.

In this manner, what does the pulling apart of continental plates create?

A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust.

Likewise, what industry has caused severe environmental damage to the Niger Delta? Crude oil is known to contain heavy metals and oil spills contaminate the environment and can result in human exposures to heavy metals. As the seat of crude oil activities, the Niger Delta region experiences the highest rate of oil spills in Nigeria.

What causes continental drift?

The causes of continental drift are perfectly explained by the plate tectonic theory. The earth's outer shell is composed of plates that move a little bit every year. Heat coming from the interior of the earth triggers this movement to occur through convection currents inside the mantle.

What are the 3 causes of plate movement?

Mantle convection currents, ridge push and slab pull are three of the forces that have been proposed as the main drivers of plate movement (based on What drives the plates? Pete Loader). There are a number of competing theories that attempt to explain what drives the movement of tectonic plates.

What happens when two continental plates collide?

Plates Collide When two plates carrying continents collide, the continental crust buckles and rocks pile up, creating towering mountain ranges. The Himalayas were born when the Indian subcontinent smashed into Asia 45 million years ago.

What is it called when two plates meet?

The location where two plates meet is called a plate boundary. Plate boundaries are commonly associated with geological events such as earthquakes and the creation of topographic features such as mountains, volcanoes, mid-ocean ridges, and oceanic trenches.

What major plate is the largest?

Pacific plate

What landform is created when two continental plates collide?

Collision boundaries form great mountain chains on Earth. The European Alps and the Himalaya Range are examples of the land forms visible on Earth where continental crusts came together. Great volcanic mountains like Mount Rainier form in a subduction zone on the continental side of a subduction zone.

What are the 12 major plates?

Primary plates

• African plate.
• Antarctic plate.
• Indo-Australian plate.
• North American plate.
• Pacific plate.
• South American plate.
• Eurasian plate.

What happens when two plates of oceanic crust collide?

When two plates collide, the density of the plates determines which one comes out on top. Oceanic crust becomes cooler and denser as it spreads away from the mid-ocean ridge. Where two plates carrying oceanic crust meet at a trench, the plate that is more dense sinks under the other plate.

What percent of Africa is Savanna?

65 percent

What percent of Africa is desert?

25 percent

What is a steep slope with plateau on top?

An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations. Usually scarp and scarp face are used interchangeably with escarpment.

Is Africa mostly desert?

Africa, the second largest continent in the world, has a variety of geographic features and vegetation zones. Many people think of Africa as consisting mostly of vast stretches of dry desert. While the Sahara Desert covers approximately one third of th e continent, it is not the largest vegetation zone.

What takes up the southern edge of the Sahara?

The Sahara divides the continent into North and Sub-Saharan Africa. The southern border of the Sahara is marked by a band of semiarid savanna called the Sahel; south of the Sahel lies the lusher Sudan.

Why is half of Africa desert?

African deserts are the sunniest and the driest parts of the continent, owing to the prevailing presence of the subtropical ridge with subsiding, hot, dry air masses.

What is the most dominant physical feature of southern Africa?

What is the most dominant physical feature of Southern Africa? Looming up behind this coastal plain are high steep cliffs known as the Great Escarpment. These cliffs form an almost unbroken U-shape.

What are two significant geographic features of East Africa?

The physical geography of East Africa is dominated by the Great Rift Valley, which extends through the middle of the region from north to south. Associated with the rift valleys are vast savannas such as the Serengeti Plain, large lakes, high mountains, and the highlands of Ethiopia.

What covers most North Africa?

The world's largest hot desert, the Sahara covers most of North Africa.

Why is Africa called the plateau continent?

Why Is Africa Called the "plateau Continent"? Africa is called a "plateau continent" because much of the land is raised well above sea level, dropping off sharply near the coastline.

What does Niger Delta mean?

The Niger Delta is the delta of the Niger River sitting directly on the Gulf of Guinea on the Atlantic Ocean in Nigeria. The Niger Delta is a very densely populated region sometimes called the Oil Rivers because it was once a major producer of palm oil.
