How are minerals formed by crystallization from magma

Geography
1 answer:

Answer:

Minerals are formed by crystallization of magma or lava. Crystallization involves a process by which atoms are  laid out to form a material with a crystal structure.

Explanation:

Minerals get created by crystallization of magma which involves cooling of magma inside the crust or crystallization of lava which involves cooling and hardening of lava on the surface. When magma or lava cools down and comes to a solid state, they create crystals.  The size of these crystals depend on three factors. They are:

  • The amount of gas magma holds.
  • The chemical composition of magma.
  • The rate at which magma cools  down: Slow cooling causes formation of large crystals.  While cooling down, if they remain undisturbed, then they grow  in a regular pattern.  Magma or lava that is closer to the surface cools down at a faster rate than magma that  hardens deep below the ground.  Rapid cooling leaves no time for magma to form large  crystals.  If magma erupts and spreads on the surface, it becomes lava which cools down quickly and forms minerals with small crystals.

How do you find the contour interval on a map?
PolarNik [594]

Answer:

How do you find the contour interval on a map?

Explanation:

near Denver might have index contours of 5,000', 5,100' and so on with a contour interval of 20 feet. This means that there would be five "spaces," and four non-index contour lines, between each index contour. Often, index points are given along with index contours.

mixas84 [53]

Answer:

A

Explanation:

Olive trees are found largely along the coast of Mediterranean climates where the have the ideal precipitation and temperature conditions to thrive. In the mountainous areas further inland, the trees would have to adapt to more extreme temperatures and generally dryer conditions.

The Arabian peninsula does not feature a Mediterranean climate, but instead a desert climate that does not permit the growth of trees outside oases.

4 men and 6 women can complete a work in 8 days, while 3 men and 7 women can complete
olga nikolaevna [1]
4 men x 8 days = 32 days work content & 6 women x 8 days = 48 work content

6 women at 1/400 per day x 8 days is 48/400. 352+ so 1 mans daily output is 11 work units per day x 4 men = 44 work output per day x 8 days = 352 total work output

3 men x 10 days = 30 days work content & 7 women x 10 days = 70 work content
1 man work output is 11 x 3 men x 10 days = 333 work units

one woman’s work output is 1/400 per day x 7 women = 7/400 per day x 10 days = Total of 70 work output plus men’s output of 330 = 400 work units.

10 women x 40 days = 400 work content

so if 10 men carried out the work its 11 x 10 men = 110 work units per day

400 work units + 110 work units per day = 3.6363 days work for 10 men.

1 women daily work output = 1/400 unit per person x 10 women or 10/400 work units per day so 10 x 40 days

4 Men & 6 Women = 8 days (men = 4 x 8 x 11 = 352)( 6 x 8 x 1/40 = 48/40
3 Men & 7 Women=10 days (men = 3 x 10 x 11 = 330)(7 x 10 x 1/40 =70/40)
10 women at 1/400 each per day x 40 days is 400 work units

while 10 men x 11 units is 110 units per day so for 400 units it’s 3.6363 days

1 man is equal approximately to 11 Women

10 men can do job in 3.6363 days x ratio of 11 =

Answer: It will taken 10 women x 40 days to complete the same job.
