Which of the following geographic features sits on a divergent plate boundary?

A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.

Where does the heat exchange occur that moves tectonic plates?

Heat is continuously flowing outward from Earth’s interior, and the transfer of heat from the core to the mantle causes convection in the mantle (Figure 1.7). This convection is the primary driving force for the movement of tectonic plates.

What geologic structures are created when one tectonic plate dives below another?

In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.

What continent is most affected by water scarcity?

Sub-Saharan Africa has the largest number of water-stressed countries of any region.

Which of the following are created along divergent plate boundaries?

Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.

Where is a divergent boundary most likely to be found?

mid-ocean oceanic ridges
Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land). The mid-ocean ridge system is a giant undersea mountain range, and is the largest geological feature on Earth; at 65,000 km long and about 1000 km wide, it covers 23% of Earth’s surface (Figure 4.5.

What type of plate boundaries exist in South American and Antarctic plates?

The easterly edge is a divergent boundary with the African Plate; the southerly edge is a complex boundary with the Antarctic Plate, the Scotia Plate, and the Sandwich Plate; the westerly edge is a convergent boundary with the subducting Nazca Plate; and the northerly edge is a boundary with the Caribbean Plate and the …

Which type of tectonic plates move towards each other?

Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries.

What type of heat transfer is tectonic plates moving?

Convection & Convection Currents

Heat from the core and the mantle causes convection currents in the mantle. This is how the heat is transferred, and how the earth’s plates are able to move. There are three kinds of plate boundaries: divergent boundaries – when the plates divide/ seperate and create a rift.

What type of heat transfer drives plate tectonics?

Convection
Convection, or the flow of mantle material transporting heat, drives plate tectonics.

When convergent plates collide and both are continental plates what geologic feature is formed?

The compressional forces stemming from a convergent plate boundary, where two plates collide with one another, can create fold mountains. This may involve the collision of two continental plates or a continental plate and oceanic plate, forcing sedimentary rocks upwards into a series of folds.

What type of plate tectonic boundary is associated with the Marianas Trench?

The boundary between the Mariana and the Pacific Plate to the east is a subduction zone with the Pacific Plate subducting beneath the Mariana.

What type of plate boundary is formed between two plates sliding past each other?

transform fault boundary
When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed. No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault.

Which regions are called water stressed countries?

Twelve of the 17 most water-stressed countries are in the Middle East and North Africa, with Qatar, Israel and Lebanon topping the list. According to the WRI, hot and dry conditions mean water supply in the region is low to begin with, but population growth has put more demand on existing resources.

Where is the most water scarcity?

Focus Areas. The Middle East and North Africa (MENA)* is the most water-scarce region of the world. Home to 6.3 percent of the world’s population, the region contains only 1.4 percent of the world’s renewable fresh water. As population pressures in the region increase, the demand for water resources rises.

Where in the Middle East and North Africa do they deal with scarcity of water issues?

Jordan, located in the Syrian Desert, and Yemen, on the southern tip of the Arabian Peninsula, both endure severe water scarcity in the Middle East.

Which country has the cleanest water?

1) Switzerland

Switzerland is repeatedly recognized as a country with the best quality tap water in the world. The country has strict water treatment standards and superior natural resources with an average rainfall per year of 60.5 inches. In fact, 80% of the drinking water comes from natural springs and groundwater.

Which zone is formed in the divergent plate boundary?

Divergent boundaries within continents initially produce rifts, which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges.

Which of the following is formed through divergence of plates?

When two plates move away from one another, the space left behind is filled with magma and other material from inside the earth. If this happens in the ocean, an oceanic ridge forms or a volcanic island. If two plates diverge within a continent, then a rift will form and this rift will eventually become a valley.

What kind of landform is created at divergent?

Two landforms that are created from divergent boundaries are rift valleys and mid-oceanic ridges.

Where is a divergent boundary most likely to be found quizlet?

Most are in the ocean (Mid Atlantic Ridge). The Great Rift Valley in Africa is an example of a divergent plate boundary on land. Eventually The Great Rift Valley will fill with water and become a sea. Places where tectonic plates move apart.

Where are convergent plate boundaries found?

In the ocean basins, convergent plate margins are marked by deep trenches in the sea floor. The convergent plate boundaries that occur on continents are the collisional mountain belts. Following are 3 examples of different tectonic settings of convergent plate boundaries.

What are divergent boundaries?

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. The Mid-Atlantic Ridge is an example of divergent plate boundaries.

Is the Antarctic Plate convergent or divergent?

Divergent Boundaries

-The Antarctic forms an underwater divergent boundary with the Pacific Plate and the South American Plate.

What type of plate boundary is the Antarctic Plate?

divergent plate boundaries
Today, about 95% of the Antarctic plate is surrounded by divergent plate boundaries: the Southwest Indian Ridge, the Southeast Indian Ridge, and the American-Antarctica Ridge.

What type of plate boundary is the Antarctic Plate and Pacific Plate?

The southern side is a divergent boundary with the Antarctic Plate forming the Pacific–Antarctic Ridge.

How often do plate tectonics move?

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.

What type of plate boundary do most volcanoes occur along?

divergent plate boundaries
Sometimes, the plates collide with one another or move apart. Volcanoes are most common in these geologically active boundaries. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries.

Are the Pacific Plate and the Antarctic Plate moving toward each other?

Are the Pacific Plate and the Antarctic Plate moving toward each other, away from each other or past each other? There is a spreading center between the Pacific and Antarctic plates so they are moving away from each other.
