Quick Answer: In what geographical direction that South America is moving away from Africa based on the current position of the continents?

The two continents are moving away from each other at the rate of about 2.5 centimeters (1 inch) per year. Using this standard South America is moving west away from Africa.

In what direction is South America moving away from Africa based on the current position of the continents?

Based on the current position of the continents South America is moving away from Africa in the direction of (a) west. Explanation: Antarctic plate, South America plate This plate starts at the western edge of South America and stretches east into the southwestern part of the Atlantic Ocean.

What direction is South America Moving?

Geological research suggests that the South American Plate is moving westward away from the Mid-Atlantic Ridge: “Parts of the plate boundaries consisting of alternations of relatively short transform fault and spreading ridge segments are represented by a boundary following the general trend.” As a result, the eastward …

How did South America and Africa move away from each other?

Chapter 2: How did the South American Plate and African Plate move? Students figure out: The South American and African plates moved apart as a divergent boundary formed between them and an ocean basin formed and spread. Earth’s plates move on top of a soft, solid layer of rock called the mantle.

Why is South America moving away from Africa?

According to the study, the tectonic plates attached to the Americas are moving apart from those attached to Europe and Africa by four centimetres each year. … Researchers reported that it is typically believed that the shifting of tectonic plates is driven by forces of gravity or the plates sinking back into the Earth.

What direction does South America is moving away from Africa?

The two continents are moving away from each other at the rate of about 2.5 centimeters (1 inch) per year. Using this standard South America is moving west away from Africa.

What is the geologic features of oceanic oceanic?

There are many geologic features on the ocean floor. Trenches, ridges, rises, and islands are the result of continental or oceanic plate movement. Volcanic eruptions and earthquakes are also the result of tectonic plate movement.

Which direction is the African plate moving?

For millions of years the African plate, which contains part of the Mediterranean seabed, has been moving northward toward the Eurasian Plate at a rate of about an inch every 2.5 years (a centimeter a year).

What is Antarctic and South American Plate?

The South American–Antarctic Ridge (SAAR or AAR) is the tectonic spreading center between the South American Plate and the Antarctic Plate. It runs along the sea-floor from the Bouvet Triple Junction in the South Atlantic Ocean south-westward to a major transform fault boundary east of the South Sandwich Islands.

What direction is the Antarctic Plate moving?

Antarctic plate, South America plate. This plate starts at the western edge of South America and stretches east into the southwestern parst of the Atlantic Ocean. This plate moves north and slightly west towards the Caribbean plate and the North America plate.

What type of plate boundary is located halfway between South America and Africa?

The Mid Atlantic Ridge, like other ocean ridge systems, has developed as a consequence of the divergent motion between the Eurasian and North American, and African and South American Plates.

Why the East Coast of South America is shaped like the west coast of Africa?

The Atlantic coasts of Africa and South America appear to fit together neatly, like the pieces of a jigsaw puzzle. The same shape is also traced out by the Mid-Atlantic Ridge, shown on this map by the light-colored area (representing relatively shallow seas) between the two continents.

How long it took for South America and Africa to move far away from each other?

The research team looked at the ancient supercontinent of Pangaea, which now accounts for South America, Africa, Antarctica, India, and Australia. For 40 million years, the plates that made up Pangaea moved apart from each other at a rate of 1 millimetre a year.

Is South American Plate oceanic or continental?

two of these plates—the continental South American Plate and the oceanic Nazca Plate—gave rise to the orogenic (mountain-building) activity that produced the Andes.

What plate boundaries are Antarctic and South American plates?

The two longest boundaries—those with the Antarctic and South American plates—are both sinistral strike-slip boundaries (Thomas et al., 2003). The southern border with the Antarctic plate, known as the South Scotia Ridge, moves with a rate of 7.5-9.5 mm/yr.

Is South America and Africa moving further apart?

The continents are still moving today. … The two continents are moving away from each other at the rate of about 2.5 centimeters (1 inch) per year. Rift valleys are sites where a continental landmass is ripping itself apart. Africa, for example, will eventually split along the Great Rift Valley system.
