Earth Science Concepts and Principles

Mr. Jansen guides students through the last 10 of the 100 illustrated ways to pass the Earth Science Regents exam. The video covers topics such as plate tectonics, types of plate boundaries, mountain formation, radioactive decay, index fossils, and the principle of cross-cutting relationships. It emphasizes the importance of using reference tables for test preparation and understanding geological concepts.

What is the primary cause of the movement of Earth's tectonic plates?

• Solar radiation

• Ocean tides

• Convection currents in the mantle

• Wind currents

Which type of plate boundary is associated with the San Andreas Fault?

• Divergent

• Convergent

• Subduction

• Transform

What geological process is responsible for the formation of the Himalayas?

• Divergence of tectonic plates

• Convergence of tectonic plates

• Volcanic activity

• Erosion by wind

What remains constant for a radioactive element regardless of external conditions?

• Its temperature

• Its mass

• Its half-life

• Its volume

Which radioactive isotope is used to date ancient rocks?

• Thorium-232

• Potassium-40

• Uranium-238

• Carbon-14

What is the half-life of carbon-14?

Which of the following is a characteristic of index fossils?

• They are found in igneous rocks.

• They lived for a long period of time.

• They are widespread and lived for a short time.

• They are found only in one location.

In undisturbed strata, which layer is the oldest?

• The middle layer

• All layers are the same age

What principle states that intrusions and faults are younger than the rocks they cut through?

• Principle of Original Horizontality

• Principle of Cross-Cutting Relationships

• Principle of Lateral Continuity
