How to determine strike and dip.

Discover the causes of foliation in metamorphic rocks. Understand foliation differences, and investigate examples of slate, schist, and gneiss foliation.

Understanding angular momentum means understanding the interaction between a rotating object and its moment of inertia. Learn about rotating bodies, moments of inertia, and the conservation of momentum, and work through sample problems to facilitate understanding of the covered concepts.

Economic geology is the study of the formation or extraction of elemental materials that have some economic potential to serve society financially. Learn more about economical geology, its types, differentiation, value and how it is graded.

Ore deposits usually contain minerals that are high in demand, and this makes these deposits extremely valuable. Learn about ore deposits and understand the economic forces involved in distinguishing them from other mineral deposits.

Learn the definition of a fold in geology. Discover different types of folds, including asymmetrical and symmetrical folds, and what causes a rock to fold.

Different types of maps can be useful in examining geographical sites. Learn how to draw a field sketch, a flow map, and a sketch map, and what should be included in each.

Atmospheric instability refers to a difference in temperature causing the rising and sinking of air. Learn about the types of lifting, how air instability is increased, and ways that air can be stabilized, noting attributable weather patterns.

What is an ideal gas and the law relating to the pressure, volume, and temperature of the ideal gas? Learn about an ideal gas constant and its characteristics.

Learn about types of unconformities in geology. Study the unconformity definition, discover unconformity examples, and learn how to identify rock unconformities.

Explore the steps and function of creating a cross-section using a topographic map. Discover the characteristics of topographic maps, the information they present, how to read a topographic map, and the four steps to creating a cross-section.

Learn what a topographic map is. Various topographic map examples will be used so that topographic features and the purpose of topographic maps can be understood.

Mineral deposits are usually located in tectonic plate boundaries due to the shifting of the plates. Learn about plate tectonics and mineral resources, and explore different plate environments, including divergent boundaries, subduction zones, and transform boundaries.

In this lesson, learn what a climograph is and how to read a climograph to derive information. See climograph examples to understand its uses.

Minutes after the Big Bang, the universe began expanding and evolving. Explore the evolution of the early universe and how the first four stages (the radiation era, recombination (decoupling) epoch, the dark age, and reionization era) contributed to the creation of all things.

Non-silicate minerals lack silicon but are still an important part of the earth's composition. Learn to differentiate silicate from non-silicate materials and study the chemical classifications of non-silicate minerals through examples such as carbonates, sulfates, and halides.

What type of rock is gabbro? Learn about gabbro, including how gabbro is formed, its texture and composition, its minerals, and its nature as an igneous rock.
