What are alkali and alkaline earth metals
They both basically belongs to the S-Block of the periodic table. Alkali metals are the 1st group elements and alkaline earth metals are 2nd group elements
Answer later
is earth system and science branch is Quivalevnt to applied geology?
Hi there. In response to your question the answer would be negative. Both of these branches are actually quite different which can be verified from the fact and brochure of a reputed institution offering both of these courses. The course pattern and subjects taught focus on different methodologies and hence it makes it different.
Hope this answer helps; best wishes
what is the name of primitive land surface of the earth
Hey there!
Hope you are doing great. The primitive surface of the earth is known as "Crust". Earth is divided into 4 layers. First one, is crust, it the outermost layer, where the landforms, air and water are covered. Second one is mantle, third goes the inner core and finally the deepest layer is the outer core.
Hope it helps!

Why do we live in earth and why do we come to earth
Hello Ashish
We must have food, water, air, and shelter to survive. If any one of these basic needs is not met, then humans cannot survive and for all these things are easily available on EARTH thats why we live on earth.
The metallic hailstorm that ensued likely lasted years, if not centuries, ripping oxygen atoms from water molecules and leaving hydrogen behind. The oxygens were then free to link with iron, creating vast rust-colored deposits of iron oxide across our planet's surface. The hydrogen formed a dense atmosphere that likely lasted 200 million years as it ever so slowly dissipated into space.
After things cooled down, simple organic molecules began to form under the blanket of hydrogen. Those molecules, some scientists think, eventually linked up to form RNA, a molecular player long credited as essential for life's dawn. In short, the stage for life's emergence was set almost as soon as our planet was born.
Thanks
