This is false, as the equator does not run north-south. The equators is the line that goes all around the planet in equal distance from the two poles: so it runs west-east.
It is true however that it runs roughly through the middle of the continent of Africa, but rather on the west-east axis.

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.
Answer:
7.0 - 1.4 = 6.4
Explanation:
the pollution is increasing 1850 to1960 in a constant speed but from the year 1970 it start increasing very fastly
The different standard times are known as time zones. Time zones are useful because they can allow people to be active during the day and sleep during the night. If people spent hours with sunlight sleeping and worked in the dark, they would likely suffer health problems.
Big countries such as Australia and the United States have many time zones so that people can work and sleep in the time that is adjusted to the hours with sunlight in their specific location.
