Equinoxes: This refers to periods of time when the mid-day sun is directly overhead at the equator. It occurs on March 21st and September 23rd when equal day and equal night exist, that is 12 hours of darkness. March 21st is called spring equinox while September 23rd is called Autumn equinox.
Great Circles: These are those circles that divides the globe into two halves or hemispheres. The equator is a great circle and all lines of longitude including the Greenwich meridian line. There are lots of great circles existing and they extend in any direction East to West, north to South and so on.
Twilight period is longer along the artic circle than the equator because at the equator, the sun rises and sets rapidly where as the artic circle, the sun rises and set more slowly. At the equator, the sun rises vertically from the horizon but it rises and sets at low angles in the artic circle.

(i) It involves blowing.
(ii) It involves rolling of loose material along the ground.
(iii) It usually results in lowering of land surface.
(iv) Deflation is associated with wind.
(i) It involves hauling rock against rock surface by wind.
(ii) Rock surface are polished, scratched and worn away.
(iii) Abrasion is most effective at the base of rocks.
(iv) Abrasion can be caused by wind, water and wave.
Examples of Abrasion is ZEUGEN:
Zeugen is formed when a tabular mass of rock which has a layer of soft rock lies under a layer of a more resistant hard rock. It is lying horizontally to the direction of wind. The mass of rock is then attacked by wind Abrasion. This wind abrasion wears the mass into a ridge and furrow landscape leading to the formation by opening up joints of the surface of hard rocks.
(i) In arid regions, temperatures change greatly from night to day, which produces wind.
(ii) Because in humid regions smaller particles are held together by the moisture in the soil and by plant roots from the vegetation
(i) Tabular data
(ii) Land surveying
(iii) Remote sensing
(iv) Map scanning
Remote sensing provide extremely useful tools for environmental and natural resources management. Remote consists of the main sources of digital data for input in a GIS. Remote sensing are widely recognized as supporting and management of appropriate utilization of resources at the country, regional and global levels.
(ii) Coastal development and management.
