Answer:

a) Mid ocean ridges

Explanation:

  • The mid-oceanic ridges underling the hot asthenosphere which creates a depression that causes the melting of the peridotites at shallow depths. As they rise that results in mafic magma and this only takes place at divergent boundaries.
  • Here the plates sperate and move away, causing magma below to rise and ill spaces of low pressure. The rocks then cool and new crust is firmed. The mafic rocks crystallize at higher temperatures and pressure.

IrinaK [193]

<u>Erosional deformation </u>   is not a form of rock deformation.

Answer: Option B

<u>Explanation:</u>

Rocks are all the time being subjected to force within the surface of earth because of which these rocks tend to twist, bend or get fractured. This causes the rock to change in their shape or size which is known as the deformation of rock and this deformation is affected by temperature, rock type, time and the pressure. Rocks deform in two ways which are ductile and brittle deformation.

What are the similarities between the North-west Passage and the Khyber Pass?
sergejj [24]

Answer:

Explanation:

Khyber Pass, Khyber also spelled Khaybar, orKhaibar, most northerly and important of the passes between Afghanistan and Pakistan. The pass connects Kābul with Peshāwar. The pass has historically been the gateway for invasions of the Indian subcontinent from the northwest. The name Khyber is also applied to the range of arid, broken hills through which the pass runs and which form the last spurs of the Spin Ghar (Safīd Kūh) Range. On either side of the connecting ridge are the sources of two small streams, the beds of which form the Khyber gorge. This narrow gorge forms the Khyber Pass; it winds between cliffs of shale and limestone, 600–1,000 feet (180–300 m) high, and enters the Khyber Hills from the Shadi Bagiār opening, a few miles beyond Jamrūd, Pak., and continues northwestward for about 33 miles (53 km). Just beyond the old Afghan fort of Haft Chāh, it opens onto the barren Lowyah Dakkah plain, which stretches to the Kābul River.

The Northwest Passage is a sea route that connects the Atlantic and Pacific Oceans through the Canadian Arctic Archipelago. In the past, the Northwest Passage has been virtually impassable because it was covered by thick, year-round sea ice.

djyliett [7]
A. The spelling of the two words might be similar and some sounds might be the same.

Although it is possible for words in two different languages to have the same spelling and/or pronunciation, it is much more likely that they would be similar. Since, the languages are derived from the same root and belong to the same family, it would make sense that the words would be similar, if not exactly the same.
