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.
How the Rock Cycle Recycles Earth’s Crust
If you could speed up time, you would see rocks cycling from within the planet. Like a well-oiled machine, rocks are igneous, sedimentary and metamorphic.
Chemical Weathering: Hydrolysis, Oxidation and Acidic Reactions
Chemical weathering is the process of transforming a rock’s composition through chemical reactions (by dissolving or converting them into other minerals)
Eurasian Plate: Tectonic Boundary and Movement
Sandwiched between the North American & African Plates, the Eurasian Plate consists of parts of Europe, Russia, Asia as well as the Atlantic & Arctic Ocean.
The Mesozoic Era: The Age of Reptiles, Dinosaurs and Conifers
The Mesozoic Era had a lot of “firsts”. For example, it had the first birds, first mammals, first dinosaurs and first flowering plants on Earth.
What Are the 3 Types of Rocks?
Earth is covered with these 3 types of rocks are: (1) sedimentary rocks (2) metamorphic rocks and (3) igneous rocks. How they are different from each other?
Earth Crust: Oceanic Crust vs Continental Crust
Earth’s crust is all around us. It’s the layer we live on. But did you know that Earth’s crust is composed of oceanic and continental and oceanic crust?
Plate Tectonic Types: Divergent, Convergent and Transform Plates
Plate boundaries interact with each other in 3 primary ways. The types of plate tectonic boundares are divergent, convergent and transform (conservative).
What’s the Difference Between Lava and Magma?
Magma is liquid rock with dissolved gas at the interior of Earth. When magma reaches the surface, it’s lava. The difference for lava vs magma is location.
