Explanation:

This is not pole reversal. Pole reversal does not control how a rocks are formed, they only align the orientation of magnetic minerals in a cooling rock.

Pole reversals occur when the direction of the magnetic north and south changes.

  • The rock type with the quartz band oriented perpendicularly from one another must have been formed along a fracture in the rock formation.
  • Fractures structurally controls how intrusions are formed.
  • The quartz band must have been a fluid from a magmatic body that crystallizes at the late stage with some other minerals.
  • Fractures acts as weakness planes in rocks and they are utilized by intrusive bodies to cool.

What are the four different cloud groups and how are they classified?
lara31 [8.8K]
1. High clouds—composed almost entirely of ice crystals, the bases of these clouds start at 16,500 feet (5,032 meters) and reach 45,000 feet (13,725 meters).

2. Cirrus —thin feather-like crystal clouds in patches or narrow bands. The large ice crystals that often trail downward in well-defined wisps are called mare's tails.

3. Cirrostratusis—a thin, white cloud layer that resembles a veil or sheet. This layer can be striated or fibrous. Because of the ice content, these clouds are associated with the halos that surround the sun or moon.

<span>4. Cirrocumulus—thin clouds that appear as small white flakes or cotton patches and may contain super-cooled water.</span>

What happens in winter in the Northern Hemisphere when the North Pole tilts away from the sun?
murzikaleks [220]

Answer:

B. Rays of sunlight hit less directly. The days are shorter and temperature colder.

Explanation:

When the north pole tilts away from the sun, the sun's rays are displaced below the equator line, that is, towards the southern hemisphere. It causes the northern hemisphere to receive fewer solar rays and to receive them indirectly, which leaves the atmosphere cooler and decreases the length of the day. This moment coincides with winter and autumn in the northern hemisphere. This inclination of the north pole lasts six months and after that period the moment of inclination of the south pole begins, which causes the sun's rays to be displaced towards the northern hemisphere.
