Photosphere temperature : 5‚770 K Core temperature : 150‚000‚000 K Absolute visual magnitude : 4.75 Rotation (as seen from the earth at the equator) : 25.38 days Rotation (near the poles) : 33 days The sun consists of 71% of Hydrogen‚ 26.5% Helium and 2.5% of other elements. The rays of the Sun take about 8 minutes to reach the earth. PLANETS (1) MERCURY : It is the planet nearest to

Exercise 17 Problems - Part I: Answers 1. The temperature contrast between the equator and the Arctic region is greatest in the winter‚ because the Arctic region is furthest away from the Sun during that time. 2. (a) The one region of the world where the hypothetical isotherm pattern is actually observed is in the Southern Hemisphere‚ starting at approximately 30° S. (b) The hypothetical pattern is seen here‚ because the oceanic and atmospheric circulations in this region constantly run from

Its greatest extent is found in the lowlands of the Amazon‚ Congo D.R‚ Malaysia and the East Indies. -Further away from the equator‚ the influence on the on-shore Trade Winds gives rise to a modified type of equatorial climate with the Monsoon influences. -Within the tropics‚ the equatorial highlands have a distinctively cooler climate‚ modified by altitude such as the Cameron highlands‚ northern

pressure cells to form. With three cells in total‚ the first being the Hadley cell‚ devised in 1686 and revised in 1735‚ Hadley proposed that warm tropical air rises and spreads towards the poles at high altitudes‚ with a return flow towards the equator at low level. He added in 1735 the effects of the Earth’s rotation‚ deflecting winds towards the right hemisphere and to the left in the southern hemisphere; this however failed to explain westerly winds in the temperature latitudes. In 1856 Ferrel

longitude: meridians are lines of constant longitude. The plane through the centre of the Earth and orthogonal to the rotation axis intersects the surface in a great circle called the equator. Planes parallel to the equatorial plane intersect the surface in circles of constant latitude; these are the parallels. The equator has a latitude of 0°‚ the North pole has a latitude of 90° north (written 90° N or +90°)‚ and the South pole has a latitude of 90° south (written 90° S or −90°). The latitude of an

passes almost in the middle of India‚ so definitely KanyaKumari is to the south of Tropic of cancer. But as we know the Equator does pass through India. So these two statements prove that KanyaKumari is North to the equator and South to the Tropic of Cancer. The location of kanyakumari is as follows: South of tropic of cancer. North of tropic of capricorn as well as of equator. 4. Palghat gap is used for the internal communication between Madurai to Trivanantapuram. The palghat gap separates the
