Stratigraphy is a branch of geology which studies rock layers (strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks. Stratigraphy has two related subfields: lithologic stratigraphy or lithostratigraphy, and biologic stratigraphy or biostratigraphy.
Answer:
The study of the interaction of electrical and magnetic fields, and their interaction with matter, is called Electromagnetism
Answer:
1.solar energy drives the cycle by evaporating water from its source and water moves from plants by the process of transpiration
2. in precipitation because the water falls from the sky
3.liquid and gas
For Ar :
1 mol ------------ 22.4 L ( at STP )
7.6 mol ---------- x L
x = 7.6 * 22.4
x = 170.24 L
-----------------------------------------------------------------
For C2H3:
1 mol ------------ 22.4 ( at STP)
0.44 mol --------- y L
y = 0.44 * 22.4
y = 9.856 L
hope this helps !.
Answer: Bonding always involve a pair of electrons and atoms and are shared between two non metals.
