This is the solid outer layer of Earth which consists of the crust and the uppermost part of the mantle.

From inward to outward, what are the layers of the earth?

This is composed of nickel-iron alloy and solid iron, and provides thermal energy for Earth.

Why does subduction form when oceanic and continental crust collide?

What is NOT true about the earth's lithosphere?

Oceanic crust is dense and ______________ while continental crust is less dense and granitic.

The asthenosphere is divided into huge slabs of solid rock called plates or tectonic plates.

_______________ are huge slabs of solid rock which are capable of moving due to the earth's internal energy.

The major plates consist of the Pacific Ocean Plate, North America Plate, Eurasia Plate, Africa Plate, Antarctican Plate, Indo-Austrailian Plate, and South America Plate.

(Did you enjoy the previous question?) The thickest type of crust.

Which of the following is NOT found near plate boundaries?

How do scientists NOT determine the epicenter of an earthquake?

This theory states that the outer rigid layer of Earth is divided into slabs of rock called tectonic plates that move across the earth's surface relative to each other, like slabs of ice on a lake.

Is the epicenter directly above, below, or the center of the focus?

What exactly is an epicenter?

The method that records seismic activities in at least 3 seismic stations, and is used as basis for finding the location of the earthquake epicenter.

Which is BEST to prove that tectonic plates are formed from a single huge continent?

Moving on to plate boundaries...what are the 3 types?

This occurs when the denser oceanic crust sinks beneath the continental crust.

This creates a gap as the rock layers of the plates grind past each other.

The Continental Drift Theory was proposed by none other than...

Oceanographers who further developed the idea that the seafloors were spreading.

Which of the following land features will NOT most likely be found along with the convergence of oceanic plates?

What plate does the Philippines sit on?

Along what boundary does strike-slip fault occur along?

All the following statements define the Pangaea EXCEPT:

This is defined as the process where the molten material flows out during divergent, and it cooled and solidified on the surface.

Formation of mid-ocean ridges on the seafloor proves evidence of continental drift-theory.

Which BEST explains Plate Tectonic Theory?

Which is NOT considered the major setback of continental drift theory?
