Question
Scientists observe several strata that are tilted at an angle. What most likely caused the tilting?
A. The strata were deposited at an angle.
B. Fossils were deposited within each stratum.
C. The strata were moved after they were deposited.
D. The strata were deposited in a small area.
Answer:
c) The strata moved after they were deposited
Explanation:
Strata can be defined as a layer or layers of sediments, sand e.t.c. that have been deposited at a particular area or land on the earth surface thereby leading to the formation of sedimentary rocks. Strata possesses distinct features that separates it from other layers in the rock.
Strata in rocks occur in an horizontal form or horizontally. If the strata or layers of the rocks look tilted it is because strata was moved after it was deposited.
A chemical formula is obtained from the number of atoms in a compound.
Chemical compounds are composed of atoms. The number atoms of each element in a compound determines the correct formula of the compound. Before I can write the chemical formula of any compound, I must first determine the number of each atom in the compound.
For instance, phosphorus trichloride contains one atom of phosphorus and three atoms of chlorine hence I would place a 1 in the box for P and 3 in the box for Cl.
