Satellite Remote Sensing

-The study of volcanoes and volcanic phenomena.

-The study of earthquakes and their phenomena.

-The branch of geology concerned with ordering and dating of events in the earth's history, including the origin of the earth itself.

-Satellite Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object.

Plate Tectonic Theory

I do support this theory. If you follow Christ and support the Bible, you should know about the Ark and the great flood. These plates were most definitely split up during this process and were constantly moving around, eventually ending up to where they lie now.

Seismology

• There are an average of 80 earthquakes of a magnitude with 3.0 or more in Australia each year.
• Most of the earthquakes caused on the Australian Plate are caused by thrust faulting due to the rocks being compressed.

• The average amount of earthquakes that occur per month range from 40-60.
• Scientists believe that these earthquakes are occurring because of the South American plate moving westward making it press up against the Pacific Ocean's crust.

Volcanology

• Almost all of the active volcanoes inside the South American Plate lie on the east coast.
• There are approximately 12 active volcanoes in this plate.
• Chile is the biggest country in South America with the most volcanoes, active or not.

• Active volcanoes rarely occur in the Australian Plate. You may notice though, as you move down southward, the rocks get younger. This is because as the continent moved northward the stationery hotspot formed volcanoes closer to the south.
• Most of the volcanoes that last erupted happened between 3,000-30,000,000 millions years ago.

Geochronology

Along the east coast of South America the rocks are primarily young and are almost constantly moving as opposed to the west coast where the rocks are for the most part, old and stable.

The Australian Plate is almost entirely filled with new/young rock. It's constantly being shifted and moved mostly because of where the volcanoes lie and where it's being moved after eruption.

Continental Crust vs Oceanic Crust

-The process in which structural highs in Earth's crust are created.

-The sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.

-The continental crust consists of land on top and the oceanic crust consists of water.

-The Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean.

-Mountain building refers to the geological processes that underlie the formation of mountains. These processes are associated with large-scale movements of the earth's crust.

-A general term for an underwater mountain system that consists of various mountain ranges (chains), typically having a valley known as a rift running along its spine, formed by plate tectonics.

-A process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. The Red Sea, for example, was created through seafloor spreading.
