The Physical Setting: Earth Science is related to the field of science called Earth Science.

Correlation with them has helped geologists date many New Zealand rocks, including those containing dinosaurs.

Bring relative dating principles to life with the activity Rock layers and relative dating.

Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence.

The method of reading the order is called stratigraphy (layers of rock are called strata).

In this course you will be studying the different processes, relationships, mechanisms, and concepts that help us interpret our planet Earth.

This topic will help you learn the basic skills of reading and interpreting maps.

In this topic we will focus on long term weather patterns and see how the changing Earth is responsible for creating unique areas of our planet.Some of the most useful fossils for dating purposes are very small ones.For example, microscopic dinoflagellates have been studied and dated in great detail around the world.Beaufort Group (Permian-Triassic), Karoo Basin, South Africa.Similar ripples occur in tidal environments and correct interpretation requires that the local facies content be taken into account.Some fossils, called index fossils, are particularly useful in correlating rocks.For a fossil to be a good index fossil, it needs to have lived during one specific time period, be easy to identify and have been abundant and found in many places. If you find ammonites in a rock in the South Island and also in a rock in the North Island, you can say that both rocks are Mesozoic.Moreover, we will focus in on the Greenhouse Effect and Global Warming and relate it to climate patterns.This topic looks at minerals and rocks and helps us to understand the different properties needed to identify them.Throughout the history of life, different organisms have appeared, flourished and become extinct.Many of these organisms have left their remains as fossils in sedimentary rocks.
