What is a rift valley kid definition?

: an elongated valley formed by the depression of a block of the earth’s crust between two faults or groups of faults of approximately parallel orientation.

What is a rift valley simple definition?

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 rift valley with example?

The most extensive of the continental rift valleys are those of the East African Rift System, which extend northward to the Red Sea and eastward into the Indian Ocean. Other notable examples include the Baikal Rift Valley (Russia) and the Rhine Rift Valley (Germany).

Where is the rift valley?

Eastern Africa

The Rift Valley, located in Eastern Africa, covers just over 2% of the continent and spreads over seven countries (Map 5 and Table 29). min. max. The Rift Valley consists of a group of independent interior basins, extending from Djibouti in the north to Tanzania in the south, nearly half being located in Ethiopia.

What is a rift valley called?

Rift valleys are sometimes called grabens, which means “ditch” in German. While there is no official distinction between a graben and a rift valley, a graben usually describes a small rift valley.

Why is rift valley important?

The Rift Valley has been a rich source of fossils that allow study of human evolution, especially in an area known as Piedmont. Because the rapidly eroding highlands have filled the valley with sediments, a favourable environment for the preservation of remains has been created.

What is rift valley in India?

It is one of the rivers in India that flows in a rift valley, bordered by the Satpura and Vindhya ranges. As a rift valley river, the Narmada does not form a delta; Rift valley rivers form estuaries. The other rivers which flow through rift valley include Damodar River in Chota Nagpur Plateau and Tapti.

Is son a rift valley?

The correct answer is Chambal Valley. The Chambal River is famous for its extensive ravines which it has carved along in the lower Chambal Valley. Son, Narmada, and Tapti flow across rift valley.

Where is rift valley Found in India?

In India on the southern slopes of the Vindhyachal mountain ranges, at the Malwa plateau escarpment boundary is formed, under which the rift valley is formed and Narmada river flows in this valley in west direction.

Which river flows in rift valley?

The Narmada and the Tapi are the major rivers in India that flow through rift valleys.

How long is the rift valley?

approximately 7,000 kilometres

The Great Rift Valley is a series of contiguous geographic trenches, approximately 7,000 kilometres (4,300 mi) in total length, that runs from Lebanon in Asia to Mozambique in Southeast Africa.

Which is the largest rift valley in the world?

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 the Great Rift Valley was formed?

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.

How is a rift valley formed for kids?

tectonic activity creates rift valleys



The valleys form when continental crust is pulling apart allowing the land to drop down between parallel faults. These valleys also form when oceanic plates are moving apart forming a divergent boundary.

How old is the Great Rift Valley?

30 million years

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.
