These plates “float” on “liquid-rock” , the same liquid-rock that pushes up between the plates.
The “pushing up” of the liquid-rock between the plates which moves them is known as?Sea-floor

Tectonic Plates
Sea-floor “spreading”
Liquid-rock (magma) pushes upwards until it breaks the sea’s surface.
Once above the surface of the sea the liquid rock (magma) continues to rise; cooling & forming mountains and plateaus.
As mountains and plateaus extend upwards into the atmosphere – they interact with the atmosphere creating “weather” .
Ironically, these mountains & plateau land features are now exposed to the very same weather-storm patterns the y have created by their interference with the atmosphere .

And now we’ll add another “pass” at our four terms studied so far [as] they apply to the lithosphere’s interaction with the atmosphere.
For the next four slides – drag n drop the term that applies to the statements at the top.

No one knows what truly causes significant global “cooling” which in
turn can trigger an “ice-age”.
What IS scientifically known?
There have been at least FIVE MAJOR “ice-ages” in the Earth’s history (information scientists have obtained from ice-core samples in Antarctica and Greenland et al)

1. The Earth’s Obliquity has a “wobble” which impacts the change of
seasons –and;
There are several testable hypothesis currently underway using today’s
technologies.
The two leading contending hypothesis are:
