Types of Sand Dunes

In this Geoshortqa we are going to know about types of Sand Dunes. Types of Sand Dunes, Geoshortqa Sand Dunes Sand dunes are heaps of sand found in deserts . Generally , their heights vary from a few metres to 20m , but in some cases dunes are several hundred metres high and 5 to 8 km long .   The formation of sand dunes requires  • Wind of high velocity  • Abundant sand  • Obstacles such as trees , bushes , forests , rock outcrops , walls against , which dunes may settle  • Ideal places i.e. dune complex , dune colony or dune chain . Dunes formed due to obstacles like hushes , walls etc. are called nebkhas , where dune formed besides desert depressions are called lunettes.   Dunes are classified on the basis of morphology , structure , orientation , location , internal structure , ground pattern and number of slip faces . These are the various types of sand dunes  a) Transverse Dunes are dunes deposited transverse to the prevailing winds direct...

Seven Seas of the world

 In this Geoshortqa we know about Seven Seas of the world. Seven Seas, geoshortqa "Sailing the seven seas" I'd familiar phrase in literature and song, but are there seven sea?

Important Ecology and environmental terms

In this Geoshortqa we know about some important Ecology and environmental terms i) 1869 , German biologist  Ernest Haeckel  first coin the term  ecology .
