Since the fault separates the layers, we can tell that the fault occurred after all the layers were deposited.
Answer and explanation:
On a flat, smooth surface, such as a flat mirror, all rays that strike the same direction will be reflected at the same angle.
Parallel rays that fall on a flat surface will remain parallel after reflection. The reflection on these smooth surfaces is called specular reflection.
When the surface is irregular, such as a curved or rough surface, the rays that appear at different positions on the surface arrive at different angles of incidence, because there are normal changes along the surface.
The angle of reflection remains the same as that of incidence, but they are reflected at different angles for those looking at the surface. This type of reflection is called diffuse reflection.
Answer:
the answer is d 2100 you can plus the 1200m + 900m = to 2100m

the mass of potassium iodide is 0.360 g
calculation
step 1: write the balanced molecular equation
Pb(NO3)2 (aq) + 2 Ki (s)→ Pbi2(s) + 2KNO3
step 2 ; calculate the moles of Pbi2
moles = mass /molar mass
= 0.500 g / 461 .0 g/mol =0.0011 moles
step 3: use the mole ratio to calculate the moles of Ki
Ki: Pbi2 is 2:1 therefore the moles of ki = 0.0011 x 2/1 = 0.0022 moles
step 4 : find the mass of Ki
mass= moles x molar mass
=0.0022 moles x 166g/mol =0.365 g which is approximate 0.360 g
