Question 583. Consider the following statements:
- When the Sun, the Earth and the Moon are aligned in a straight line, the position is referred to as SYZYGY.
- When the Sun and Moon are in straight line, it results in spring tide.
- When the Sun and Moon are in right angle, it results in Neap tide.
Answer: Option B. -> 1, 2 and 3
Answer: (b)
Answer: (b)
Answer: Option A. -> Both 1 and 2
Answer: (a)The nearest large galaxy of Milky Way is Andromeda galaxy. At a distance of about 2.5 million light-years, the Andromeda galaxy (also known as NGC 224 and M31) is the nearest galaxy to the Earth apart from smaller companion galaxies such as the Magellanic Clouds.The Sun’s nearest known star is a red dwarf star called Proxima Centauri, at a distance of 4.3 light-years away.

Answer: Option B. -> 1, 2, 3, 4, 5 and 6
Answer: (b) From electromagnetic radiation to the revolution of the earth, everything is responsible for bringing dynamic changes on the surface of the earth. For example,Electromagnetic radiation brings changes in the field of microwaves, wavelengths of radio, UV rays, infrared rays, X rays, and gamma rays. Geothermal energy is the heat received from the earth’s core. This heat continuously flows outward. It transfers to the surrounding layers of rock, the mantle. When temperature and pressure become very high some mantle rocks melt becoming magma. It then either comes out as lava or heats up the nearby rocks and water which comes out as hot springs or geysers. Gravitational force is constantly working on all physical bodies. It is giving weights to objects with mass and causes them to fall to the ground when dropped. Plate movement is a dynamic change on the surface of the earth. It explains many aspects of the interrelationship of volcanoes, earthquakes, climate change, and the evolution of life itself.Everything about our planet is related either directly or indirectly to plate tectonics. Rotation causes day and night. Revolution causes seasons, change in the length of day and night.

Answer: Option D. -> Kepler’s second law
Answer: (d)Kepler’s second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the sun. It states that a line between the sun and the planet sweeps equal areas in equal times.Thus, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.

Answer: Option C. -> The predominant element in the composition of Earth is silicon.
Answer: (c)The Earth is the densest of all the planets in our solar system. The density of the Earth is 5.513 g/cm3. This is an average of all of the material on the planet.
