Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.
Distance between the sun and the planet. The strength of the gravitational force or pull depends on two factors,mass and distance. for example if one of the masses is doubled, the force of gravity between the objects is doubled. The force of gravity decreases when distance between the increases
Answers and Explanations:
1. Secant line
There are various different kinds of lines in geometry, and each has its own aspects. A secant line is a line that crosses the shape or graph at exactly two points. Here, we can see that line BC crosses circle A at two points: B and C, so we know it's a secant line.
2. Chord
A line segment that connects two points on a circle without crossing the center is called a chord. Now, if the segment <em>had</em> crossed the center, then it would have been called the diameter.
3. Tangent line
As aforementioned, there are different kinds of lines in geometry. Where a secant line has two intersection points, a tangent has only one. Tangent literally means "touching", and we can see from the picture that the line running through point B is "touching" circle A at exactly one point: B.
