Which of the following provides evidence that the continents on tectonic plates have moved away from each other in the past?

1.The composition and thickness of rock layers varies at different depths.

2.The frequencey of volcanic activity is higher at edges of tectonic plates.

3.Ocean currents can be disrupted near boundaries between tectonic plates.

4.Fossils of the same plans and animals are found on widely separated continents

answer: mercury

explanation:

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
