The amount of time that the 2 species have been evolving apart??
Your answer should be lakes and forests. Acid precipitation will rot out forests because of the acid content and in lakes it raises the PH balance making it more acidic which in turn makes it harder for anything to live in these lakes or drink from them. (Hope this helps ^-^)

Earth's rotation causes the Coriolis effect.

When a hostname is configured through the Cisco CLI, some naming conventions must be follows.

3- The length of the hostname should always be less than 64 letters
The correct answer is option B. shown that the tidal forces needed to move continents would stop Earth’s rotation.
The Wegener’s idea that tidal forces might cause continental drift suggested that the tidal force and the centrifugal forces on the earth was the cause of the movement of the plates.
But, he was unable to propose the mechanism of such movement. Also, if the centrifugal force of the earth would move the plates apart, then the earth below it should remain stationary, but the earth is in continuous rotation, so, this idea was not acceptable, as it is would stop rotation of earth.
