Answer:
B. The Earth is tilted relative to the ecliptic
Explanation:
- Its due to the earth has an axial tilt of 23.5 degrees which is an inclined motion, relative to the orbital plane of rotation. This is the angle of obliquity of the earth from its center.
- For this reason, the earth has solstice in summer, winter, vernal and equinoxes and owning to the fact that the continents in the north have winter in the Northern hemisphere and continents in the south have summer.
- Without this tilt, the earth would have climatic extremes. Day and night time of the earth are also influenced by the same rotational motion.
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:
Difference is given as under
Explanation:
- Mountain belts or mountain ranges are a line of hills connected by high ground. Usually an orogeny most of them are a result of plate tectonic effects and maybe young may be old depending upon their characteristic composition. Like the Himalayas is a young fold mountain formed in the tertiary system of rocks.
- Usually, the mountain is separated from highlands, valleys, and passes. Usually, they tend to regulate the climate affecting snow and rainfall patterns. As compared to the stable interiors upon concerning their age are mostly young as they are continuously on the move and their formation is impacted by erosion and continuous wear and tear of geomaterials.
- Concerning the height, the continents are lower as compared to the high elevated landmasses. Though the continents have large landmass and landscape is composed of various elements as mountain belts are smaller as composed to chains connecting the continents at the edges and borders.
- Only continental mountain belts like the arctic and antarctic circle have a large scale of mountain chains and ranges on earth that are since millions and billions of years ago the formation of super landmasses.
All positions along a circle that runs parallel to the equator and 30° south of it.
The Soil is less rich in minerals and other things that make good fields and better crops.
