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.

Secretary of State John Foster Dulles defined the Middle East as "the area lying between and including Libya on the west and Pakistan on the east, Syria and Iraq on the North and the Arabian peninsula to the south, plus the Sudan and Ethiopia."
For Earth to make one complete revolution around the Sun takes 365.24 days. This amount of time is the definition of one year.
Effects of Revolution of the Earth: Certain areas are tipped towards, or away from, the sun at different times of the year. This tilting causes the four seasons of the year. The tilting also creates opposite seasons in the Northern and Southern Hemispheres.
If the region rises in population it will most likely cause a bigger scarcity in water, which may lead to a drought. A drought can ruin crops and leave land dry.
Answer:
Development geography is a branch of geography which refers to the standard of living and its quality of life of its human inhabitants. In this context, development is a process of change that affects peoples' lives. It may involve an improvement in the quality of life as perceived by the people undergoing change.
