Answer:
Volcanoes and Earthquakes occur more frequently where tectonic plates meet or separate
Explanation:
Volcanoes do occur underwater at mid - oceanic ridges but it often occurs when the plates are separating and this usually forms new islands
The discovery of Gold caused people to start rushing to California.
Answer:
B. He learned in the hopes of improving his life as a slave,if not total escape from slavery.
Answer:
Hail actually falls as a solid. Hailstones are formed by layers of water attaching and freezing in a large cloud. A frozen droplet begins to fall from a cloud during a storm, but is pushed back up into the cloud by a strong updraft of wind. When the hailstone is lifted, it hits liquid water droplets
Explanation:
Answer:
1. Focus
2. Aphelion
3. Ellipse
4. Semimajor axis
5. Perihelion
6. Eccentricity
Explanation:
In Kepler's first law of planetary motion, he says that planets orbit around the sun, not in perfect circles, but in ellipses (3.) the Earth also orbits the sun in this shape. The shape of the ellipse is determined by two focii. The closer these two points are to each other, the more the ellipse will resemble a circle.
The moon for example, orbits around the Earth. The moon is not always at the same distance from the Earth in all points of the orbit. So the shape is an ellipse, which is made with Earth as one of its focus(1.).
Eccentricity(6.) describes the flatness the orbit is, or how elliptical the orbit is. Remember Kepler's first law, he says that planets move in elliptical orbits and not perfect circles. So it is simply how different from a perfect circle an orbit is. Pluto is known to have a large eccentricity.
Because of the shape of an ellipse, there are going to be points where a planet is closest to the sun and where a planet is farthest from the sun. This is where Kepler's 2nd law of planetary motion comes in. When the planet is closest to the sun, this is called the perihelion (5.) where a planet would be traveling the fastest at this point of the orbit. When the planet is at its farthest point from the sun, this is called the aphelion (2.) where a planet would be traveling the slowest.
The third law of Kepler describes the relationship between the period and the average distance of the sun. The semimajor axis(4.) is the average distance of the planet object from the sun and is measured in Astonomical units (AU). The period is measured in years.
