What is the origin of rift?

A rift valley is a lowland region that forms where Earth's tectonic plates move apart, or rift. Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading.

What is the word origin of rift?

rift (n.) early 14c., "a split, a breaking, an act of tearing or rending," from a Scandinavian source (compare Danish and Norwegian rift "a cleft," Old Icelandic ript (pronounced "rift") "breach;" related to Old Norse ripa, rifa "to tear apart, break a contract" (see riven).

How was the rift created?

Rift valleys form when tectonics plates beneath the Earth's surface diverge (or move away from one another in opposite directions). It is important to note here that rift valley formation, unlike rivers and glacial valleys, are solely created as a result of tectonic plate movement.

When was the rift formed?

It included what today is called the Lebanese section of the Dead Sea Transform, the Jordan Rift Valley, Red Sea Rift and the East African Rift. These rifts and faults were formed 35 million years ago.

Where did the Rift Valley come from?

Geologists know that the Rift Valley was formed by violent subterranean forces that tore apart the earth's crust. These forces caused huge chunks of the crust to sink between parallel fault lines and force up molten rock in volcanic eruptions.

The RIFT - An In Depth Look

Did humans originate in rift valley?

The great Rift Valley that runs through Ethiopia has played a pivotal role in human evolution. It is both the location of the earliest fossils of anatomically modern humans and, later, become an important route for human migrations 'out of Africa'.

What is the oldest rift valley?

Site of some of the oldest hominid fossils, The Great Rift Valley in East Africa refers to a massive land depression, formed approximately twenty million years ago when two parallel fault lines pulled apart.

How old is rift?

The rift has been forming for some 30 million years (as Africa and the Arabian Peninsula separated) and has been accompanied by extensive volcanism along parts of its length, producing such massifs as Kilimanjaro and Mount Kenya.

When did the rift end?

The Rift lasts for 70 Days and generally opens the day after the release of a Mid-Chapter Patch (odd numbers).

What is a rift in the universe?

In astronomy, the Great Rift (sometimes called the Dark Rift or less commonly the Dark River) is a dark band caused by interstellar clouds of cosmic dust that significantly obscure (extinguish) the center and most radial sectors of the Milky Way galaxy from Earth's perspective.

What could a rift become?

Rifting and Passive Continental Margins. Rifting is defined as the splitting apart of a single tectonic plate into two or more tectonic plates separated by divergent plate boundaries. The rifting of a continental tectonic plate creates normal fault valleys, small tilted block mountains, and volcanism.

Who discovered a rift?

In 1953, American physicists Maurice Ewing (1906-1974) and Bruce Heezen (1924-1977) discovered that through this underwater mountain range ran a deep canyon. In some places the canyon, called the Great Global Rift, came very close to land.

What's the definition of a rift?

: an opening made by splitting or separation : cleft. : a normal geological fault. : a break in friendly relations : breach. rift.

What is the Norse word for rift?

Middle English rift, of North Germanic origin; akin to Danish rift, Norwegian Bokmål rift (“breach”), Old Norse rífa (“to tear”).

Is a rift a volcano?

Rift zones are areas of weakness in the volcano which form early in its lifetime, likely due to spreading of the volcano as it settles. This linear area that is being rifted, or pulled apart, remains active through most of the volcano's building stages.

Where is the rift the oldest?

Lake Baikal, the rift lake over the Baikal Rift Valley in Siberia, is the deepest and oldest freshwater lake in the world. The deepest parts of Lake Baikal are 1,642 meters (5,387 feet), and are getting deeper every year.

What is the largest rift on Earth?

The longest rift on Earth's surface, the Great Rift Valley is a long, deep depression with steep, wall-like cliffs, extending from Jordan in southwestern Asia southward through Africa to Mozambique.

How long is rift in time?

When focusing on the main objectives, Ratchet & Clank: Rift Apart is about 11 Hours in length. If you're a gamer that strives to see all aspects of the game, you are likely to spend around 18½ Hours to obtain 100% completion.

How big is rift?

Hard Drive: 15.0 GB available.

What is rift's real name?

Born Robert Pawlikowski in Paterson, New Jersey, Rift was raised in Parsippany-Troy Hills, New Jersey and moved to Los Angeles while in his mid-20s.

How long until Africa splits?

How long will Africa take to split? It is thought it will take “at least 5 million to 10 million years” before a new ocean forms and splits the continent in two.

What is the largest Rift Valley in the US?

The Great Rift is one of only two such features in the world. At 635 square miles, it is considered to be the largest, deepest, and most recent volcanic rift system in the continental United States. Many of Idaho`s most fascinating geological features lie along this potential wilderness.

Why is Africa splitting apart?

Shifting tectonic plates have been splitting the continent since the East African Rift – a 35-mile-long crack in Ethiopia's desert – emerged in 2005. Tectonic plate shifts in Ethiopia show that the African continent is splitting in two – paving the way for Earth's sixth ocean to emerge, according to researchers.

Is Africa the birthplace of the human race?

Our species, Homo sapiens, has now spread to all parts of the world but it's generally believed that we originated in Africa by about 200,000 years ago. We interacted with local archaic human populations as we colonised the globe.
