Answer:

Correct option are Basalt, gabbro and peridotite.

Explanation:

Igneous rocks like basalt, gabbro, dunite, diabase, and peridotite contains the olivine mineral. These are the dark coloured rocks and found within the surface of earth mostly in the areas around the tectonic plates. Olivine is known for its crystallization at high temperatures. It crystallize itself from the heat of the earth. Common olivine minerals are Forsterite, Fayalite, Monticellite and Tephroite.

IceJOKER [234]

Answer:

  • upwelling
  • obliquity
  • thermohaline circulation
  • Milankovitch cycles
  • eccentricity
  • precession

Explanation:

  • Upwelling is a process of the winds that drives away the warm water from the surface and bring up the cold and dense water from below.
  • Obliquity is the nature of the axial tilt of the earth i.e 23.5 ° Due to the equator bulge and other properties of the earth.
  • The thermohaline circulation is the global circulation of the waster that is created by the gradient flow of the surface heat and the freshwater influxes.
  • Milankovitch cycles are the effect of the changes in the earth's movements in climatic patterns over a thousands of years period.
  • Eccentricity is the orbital rotation of the earth around the sun on its axis and has more of a circular elliptical path.
  • The precession is the change in the orientation of the axial tilt of the planet in reference to the rotating body.

Visitors commonly note the rounded appearance of the back side of Half Dome. It was not polished by glaciers but rather fracture
ipn [44]

This process where the sheets might peel off like an onion is called exfoliation.

Rock exfoliation can be described as a process that occurs causing sheets of rocks to be peeled from the surface of a rock. The process is also describes as Onion skin weathering.

Pressure release that happens during erosion could also be responsible for this happening. Curved plates of rocks would be stripped from underneath.

All of the following are effects of rotation on the physical characteristics of Earth's surface EXCEPT:
Flura [38]

Answer:

<u>the Coriolis effect</u>

Explanation:

  • Coriolis force or effect is the effect that is produced due to the rotation of the earth on its axis and another physical feature is the same as the length of day and night, tidal motion by the air currents and seasonal changes on earth.
  • All these are physical characteristics or effects on the earth's surface. Coriolis force deflects the winds in the right direction as per the northern hemisphere and deflects the winds towards the left side of the southern hemisphere as the rotation of the earth at the speed of 460 meters per second for about 23 hours, 56 minutes and 4.0 seconds.
  • Hence,  producing equinoxes and solstices.

Based on the following chart of nuclear weapons and nuclear weapons history of the “nuclear club”, what can you infer about the
miss Akunina [59]
The answer is (B) beginning in the 1940s, both the United States and Russia lead the way and successfully testing nuclear weapons

U.S. conducted six atomic tests before Russia developed their very first atomic bomb (RDS-1) and tested it on the 29th of August, 1949. Testing these bombs back then for both countries were relatively infrequent because they did not have very many atomic bombs to spare. The Trinity was tested on the 16th of July 1945 and yielded around 20 kilotons. 

Trinity, which was conducted in New Mexico was tested to give an idea of the actual size and the after- effects of a nuclear explosion. Operation first lightning or the RDS-1 also known as Joe 1 in the west was tested on August 29th 1949 and considered this test as the first Soviet nuclear test.
