Answer:
Explanation:
The theory of plate tectonics suggests that the earth is broken into a series of slabs called lithosphere that moves over the weak asthenosphere below it.
This theory has provided insight to many chimerical observations made in earth science like volcanism, earthquakes, orogeny e.t.c.
Theory came into limelight after the second world war based on the precepts of the continental drift theory and sea floor spreading theory.
Mantle convection provides the mechanism of motion for the moving plates.
- We can explain the presence of fossils of the same plants and animals in locations that are different using this theory.
- Once in time, the earth was a united land mass.
- Therefore, geographical distribution of fossils across different terrain was not limited.
- It was after the separation of the plates that diversity started.
Answer:
it is possible to fit the shapes of all the continents onto one, so for example places in the continent of Africa fit into south america.
hope this helps, i hope this made sense.
Answer:
v = 220 m / s
Explanation:
This is a kinematics exercise, the expression for velocity is
v = 25 t² - 80 t - 200
asks the velocity for time t = 6 s.
let's calculate
v = 25 6² - 80 6 - 200
v = 220 m / s
Pasteur-Disproved spontaneous generation using S-necked flasks that were open to the air but did not let microorganisms in. Broth boiled in the flasks did not become contaminated. The organisms could have come from the air and settled into the broth. To disprove the theory of spontaneous generation, Louis Pasteur devised a way to the flask that allowed oxygen in but prevented dust from entering. Through this experiment, Pasteur demonstrated that life arises from existing life.

The number converted is
Explanation:
In order to convert from the original units to the final units, we have to keep in mind the following conversion factors:
The original unit that we have is
Therefore, it can be rewritten as:
Therefore, since the initial number was 0.779, the final value is
