The answer is A) Birth rate
<u>Answer:</u>
A solid hollow cylinder has an "infinite number of planes of symmetry".
<u>Explanation:</u>
- Two or more faces are said to be symmetric when they have the same dimensions and are geometrically identical.
- When these faces are placed in a setting with 'X', 'Y' and 'Z' axes "perpendicular to each other", they make a plane with three lines of symmetry. A circle has "infinite lines of symmetry".
- Thus, a cylinder with two openings has an "infinite number" of "planes of symmetry".
Answer:
Infrequent but highly explosive
Explanation:
At a subduction zone, the descending plate carries with it sediments containing water and carbon dioxide.
These substances are trapped as fluids at high pressure in the rising magma.
When they reach atmospheric pressure at the surface, they become gases that expand suddenly and explosively.
