Answer:
Tectonic plate motions generate volcanoes around the boundary of the plate, which erupt and form the mountains. A volcanic arc structure is a sequence of volcanoes forming near a subduction zone where the surface of a sinking oceanic plate melts and drags water down with the subducting crust.:
Answer:
Perimeter of quadrilateral = 12.35 units
Explanation:
To find - Find the perimeter of a quadrilateral with vertices at C (−2, 4), D (−3, 1), E (1, 0), and F (−1, 2).
Proof -
The figure becomes :
We have the points -
C (−2, 4),
D (−3, 1),
E (1, 0),
F (−1, 2)
Now,
We know that -
The perimeter = Distance of (CD + DE + EF + FC)
Now,
Distance of CD = √(-3 + 2)² + (1 - 4)²
= √(-1)² + (-3)²
= √1 + 9
= √10 = 3.16
⇒Distance of CD = 3.16
Now,
Distance of DE = √(1 + 3)² + (0 - 1)²
= √(4)² + (-1)²
= √16 + 1
= √17 = 4.12
⇒Distance of DE = 4.12
Now,
Distance of EF = √(-1 - 1)² + (2 - 0)²
= √(-2)² + (2)²
= √4 + 4
= √8 = 2.83
⇒Distance of EF = 2.83
Now,
Distance of FC = √(-2 + 1)² + (4 - 2)²
= √(-1)² + (2)²
= √1 + 4
= √5 = 2.24
⇒Distance of FC = 2.24
So,
Perimeter of quadrilateral = 3.16 + 4.12 + 2.83 + 2.24
= 12.35 units
⇒Perimeter of quadrilateral = 12.35 units
A pearl Harbor. that was when we went from staying neutral to entering the war
Answer:
Because the climate of Western part of the country is much more favorable in comparison to the Eastern part. Most of the Eastern part, called Siberia is practically unsettled, because the climate is unfavorable. The average temperature is below zero, and it is practically impossible to crop anything. On the other part, the more you go to west, the climate is more favorable, and also a fertile land where you can crop different vegetables is available.
Explanation:
The chernozem is characteristic not only for Western Russia, but also in the Continental Europe. For example large part of Pannonia is covered with chernozem. That is why this is the part of Russia where agriculture is boosted.
