Antarctic Plate: The Drifting Continent of Antarctica
Antarctic plate holds the continent of Antarctica including the surrounding ocean. It shares borders with the African, Pacific & South American plate.
Geology
How Do Glaciers Form?
Like a rake scraping the dirt, glaciers leave a lasting impression on the land. They can erode mountains, transport vast amount of rock and reshape the land.
Coal Formation: How Coal Forms
Hydrocarbons, oil and coal formation in general are made from living organisms that have been compacted from intense heat and pressure millions of years ago.
Mountain Building: How Mountains are Made
When convergent plates collide, the lithosphere thrusts upwards. This geologic process of vertical upheaving are orogenies or mountain building events.
African Plate and the East African Rift Zone
The African major plate contains all of Africa as well as the surrounding oceanic crust of the Atlantic Ocean. It moves at an average rate of 2.5 cm per year.

What Happened in the Archean Eon? [4.0 to 2.5 billion years ago]
Earth formed a stable climate in the Archean Eon. Because it cooled down from its molten state, Earth was able to support oceans, continents and oxygenation
Fossil Records: A Journey into the Past
When you unveil a fossil, it’s like rewinding into the past. Fossils are preserved remains from past living things such as bones, shells or exoskeletons.
Indo-Australian Plate: Tectonic Boundaries and Movement
The Indo-Australian Plate combines the Australian & Indian Plate. Widely considered two separate plates, it includes Australia, India and the Indian Ocean.
What is Isostatic Rebound?
During the last ice age, ice pushed down on continents with immense pressure. After the ice melted, land began slowly lifting which is isostatic rebound.
3 Mechanical Weathering Processes that Break Down Rocks
Mechanical weathering is the breakdown of rocks into sediments by physical means.This type of weathering does not alter the chemical composition of rocks.
5 Asthenosphere Facts: What is the Asthenosphere?
The asthenosphere is the unsung hero of our planet. This plasticky layer 80 to 200 km beneath Earth provides the necessary lubrication for plate tectonics.
South American Plate: Tectonic Boundary and Movement
The South American plate is the smallest of all major plates that includes the continent of South America and a large portion of the Atlantic Ocean.
What is a Cinder Cone Volcano (Scoria Cone)?
Cinder cones (also known as spatter cones) are the most common type of volcano in the world. But they are small in comparison to stratovolcanoes and others.
How Do Sedimentary Rocks Form?
Sedimentary rocks form from two key processes. First, compaction squeezes material together. Second, cementing glues the squeezed material together.
Proterozoic Eon: Eukaryotes to Multicellular Life (2500 to 541 million years ago)
In the Proterozoic Eon, key highlights are: ozone layer thickened, an oxygen crisis, Snowball Earth and eukaryotes and multicellular organisms evolved.
