Honduras is positioned on the Chortis Block near the junction of three tectonic plates: the North American , the Cocos, and the Carib- bean. The large arrows indicate the direction of motion of the plates. The Cocos plate is being thrust under the Caribbean plate along the Middle America Trench.
What type of boundary is the Juan de Fuca plate?
The Juan de Fuca and Gorda ridges mark the divergent plate boundary (the spreading ridge) with the Pacific plate.
Which country is on the Cocos and Caribbean plates?
The Cocos Plate in the Pacific Ocean is subducted beneath the Caribbean Plate, just off the western coast of Central America. This subduction forms the volcanoes of Guatemala, El Salvador, Nicaragua, and Costa Rica , also known as the Central America Volcanic Arc.
What tectonic plate do we live on?
California is located at the seam of the Pacific Plate , which is the world’s largest plate at 39,768,522 square miles, and the Northern American plate.
Is the South American Plate oceanic or continental?
The South American Plate is a major tectonic plate which includes the continent of South America as well as a sizable region of the Atlantic Ocean seabed extending eastward to the African Plate, with which it forms the southern part of the Mid-Atlantic Ridge.
Is the Juan de Fuca Plate getting bigger or smaller?
| Juan de Fuca Plate | Speed 1 26 mm/year (1.0 in/year) | Features Pacific Ocean | 1 Relative to the African Plate |
|---|
What is the smallest tectonic plate?
The Juan de Fuca Plate is the smallest of earth’s tectonic plates. It is approximately 250,000 square kilometers. It is located west of Washington...
Which direction is the Cocos Plate moving?
The Isla del Coco and thus the Cocos Plate is moving at a steady rate of about 91 millimeters per year in a northeast direction relative to the International Terrestrial Reference Frame (IRTF2008), based on the 10 months of data from the new island station (ISCO).
Is the Cocos Plate growing or shrinking?
The Cocos Plate, running along the ocean floor off the Pacific coast of Central America, moves 75 mm or 3 inches a year — almost 25 feet per century. That’s roughly twice the average velocity of the earth’s plates.
Is Iceland a convergent boundary?
Iceland lies on the Mid Atlantic Ridge, a divergent plate boundary where the North American Plate and the Eurasian Plate are moving away from each other.
What causes tectonic plates to move?
Earth’s crust, called the lithosphere, consists of 15 to 20 moving tectonic plates. ... The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.
What is the most active plate?
These plate boundaries are associated with geological events such as earthquakes and the creation of mountains, volcanoes and oceanic trenches. Most of the world’s active volcanoes occur along plate boundaries – the Pacific plate’s Ring of Fire is the most active.
How tectonic plates are formed?
The plates — interlocking slabs of crust that float on Earth’s viscous upper mantle — were created by a process similar to the subduction seen today when one plate dives below another , the report says. ... Other researchers have estimated that a global tectonic plate system emerged around 3 billion years ago.
How did the South American and African plates move?
How did the South American Plate and African Plate move? Earth’s plates move on top of a soft, solid layer of rock called the mantle. ... The South American and African Plates moved apart as a divergent boundary formed between them and an ocean basin formed and spread .
Why is the Nazca Plate getting smaller?
The Nazca Plate is getting smaller. ... On the Nazca Plate’s eastern boundary with the South American Plate, the Nazca Plate is forced down toward the mantle where it melts. The destruction of the eastern edge of the plate far outpaces any growth on the plate’s western edge.
Is Nazca Plate continental or oceanic?
The Nazca Plate or Nasca Plate, named after the Nazca region of southern Peru, is an oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South America.
