Tectonic is from the Greek word _____ which means _____ or _____.

Lithospheric Plates

The plate tectonics is also known as _____ _____.

Massive Slabs

_____ ___ of solid rock that surround the earth's surface.

Plate Tectonics

According to this theory, earth's outermost layer is divided into a dozen or more large and small solid plates or slabs.

Theatrum Orbis Terrarum (Abraham Ortelius)

He gave rise to the tectonic plate theory.

Clarence Edward Dutton

He proposed the term
"isostasy" to explain the concept of contracting Earth.

Isostasy

The balance or equilibrium between the Earth's rigid outer layer (lithosphere) and the underlying semi-fluid layer asthenosphere).

Alfred Wegener

He proposed the theory in his book The Origins of Continents and Ocean
