Why there is an atmosphere around the earth while many planets don't have? |
|
Answer» Actually, other planets in our solar system do have an atmosphere – certainly Venus and Mars do. The gas giants are in a sense all atmosphere. The moon however, doesn’t have atmosphere. Basically this is because it is sufficiently small that the force of gravity on the moon is so weak that it can’t hold on to any gas. Earth has more atmosphere than most of the other inner planets for three reasons. Gravity Volcanism. Temperature Being the most massive of all of the inner planets, Earth can hold more atmosphere to its surface by its gravity alone. Furthermore, volcanos continually spew out gasses into the Earth's atmosphere at a rate faster than they escape into space. Temperature is a big factor : if a planet or moon is too cold, then the atmosphere will freeze and fall to the surface. Pluto spends part of its orbit with an atmosphere, but when it’s furthest away from the Sun it freezes. On Earth, the amount of energy coming in from the Sun and being lost to space is about the same, meaning that the planet can stay at a constant temperature. |

Why do stem and root move (grow) towards light and the centre of gravity of the Earth respectively? |
|
Answer» It is due to auxins (plant hormones) produced by the shoot apex and root tip. In stem, growth is more on the shaded side (lower side of apex) due to accumulation of auxins. In root, growth is more on the illuminated side as auxins accumulated on the lower side (shaded side) of root tip inhibits the growth of that side. Thus, there is greater growth on the upper side (illuminated side), resulting in the growth of root apex towards gravity of Earth |

Explain why burning of wood and cutting it into small pieces are considered as two different types of changes. Describe how crystals of copper sulphate are prepared. |
|
Answer» Burning of wood is a chemical change because during burning new substances are formed and we cannot get back the original substance(wood) back. Cutting of wood into small pieces is a physical change because no new substances are formed. Crystals of copper sulphate are prepared in the following way: 1. Take a cup full of water in a beaker. 2. Add few drops of dilute sulphuric acid. 3. Heat the water. 4. On boiling add copper sulphate powder slowly and stir continuously. 5. Continue adding copper sulphate powder till the solution becomes saturated. 6. Filter the solution and allow it to cool. 7. The solution should be kept undisturbed. 8. Slowly the copper sulphate crystals separate out. |
