Many scientists believe that the Moon formed when a Mars-sized planet, called Theia, struck Earth around 4.5 billion years ago.

Silicates are a particularly complex class of minerals that all contain silica tetrahedra. Let's look at a few of the sub classes of silicates and the minerals in those groups to learn more about silicate structure.



The 8...

When Earth’s spinning outer core cools and becomes solid, Earth will die like Mars died.

We tend to think of Earth's landmasses as being fixed in place, but in reality they are attached to moving tectonic plates that constantly jostle for position. In some areas these tectonic plates slide over a hotspot - an...

Geology as science begins with the industrial revolution in England. For the first time rock strata are studied and compared and an amazing conclusion is drawn. Earth is unbelievably old.

Earth Science for Kids is the fun way to learn important facts about earth science and prepare for tests. Take a fascinating journey to the Super Science Station to learn about plate tectonics.

Cleavage and hardness are two macroscopic characteristics that geologists use to identify and classify minerals. How are these characteristics measured? What do they tell us about the properties of a mineral?



Macroscopic...

What mechanical process was created to help the natural process in the everglades? What is needed to learn in order to help maintain ecosystems?<br/>
The Everglades Ecosystem, Part 4

Color and luster are two important macroscopic characteristics of minerals. How can we identify and classify minerals using these characteristics? And why do the same metals show up as different colors in different...

Earth Science for Kids is the fun way to learn important facts about earth science and prepare for tests. Take a fascinating journey to the Super Science Station to learn about the Mohs hardness scale.

Alaska is home to 54 active volcanoes. Scientists, called volcanologists, watch and study these volcanoes to try and predict when they are going to erupt and so they can give warnings to the nearby communities. In 2008, Mount Redoubt,...

This video provides an overview of earthquakes, including their causes, measurement, and notable earthquakes in history. It also discusses the importance of earthquake preparedness and provides tips on how to create an emergency plan and...

Earth Science for Kids is the fun way to learn important facts about earth science and prepare for tests. Take a fascinating journey to the Super Science Station to learn about the water cycle.

Earth Science for Kids is the fun way to learn important facts about earth science and prepare for tests. Take a fascinating journey to the Super Science Station to learn about the solar system.

Seawater is an electrical conductor, and therefore interacts with Earths magnetic field. As the tides cycle around the ocean basins, the ocean water essentially tries to pull the geomagnetic field lines along. Because the salty water is...

Hawaii is known for its volcanoes, but most volcanoes on earth exist along tectonic plate lines. Hawaii does not! What causes Hawaii to form, and how is it related to the mystery of a magnetic bar code across the Pacific Ocean? Host...

In this video students will learn about unconformities and how they help geologists to discover episodes of volcanism, uplift, erosion and deposition that provide evidence for plate tectonics during Earth's history. Through video and...

Earth Science for Kids is the fun way to learn important facts about earth science and prepare for tests. Take a fascinating journey to the Super Science Station to learn about volcanoes.

Many national parks were founded for their geology, and Yosemite is known throughout the world for its exceptional high cliffs and rounded domes. Visitors to the park, from hikers to rock climbers, experience a landscape dominated by...

A fossil is a trace of a living thing left in rock. Fossils offer a three-part challenge - first to reconstruct the organism itself, then to reconstruct the world it lived in, then to understand its place in time and evolution.

This video covers the Earth and Environmental science major and places an emphasis on earth science, soil science, geology, and hydrology. The Earth and Environmental Science major is a broad major that allows students a...

Earth Science for Kids is the fun way to learn important facts about earth science and prepare for tests. Take a fascinating journey to the Super Science Station to learn about renewable energy.

The forces of sun, wind and water have changed the face of earth just as much as tectonics. Weathering and erosion are driven by gravity, flattening the landscape. They create soil. Deposition starts the process of forming sedimentary rock.

Earth Science for Kids is the fun way to learn important facts about earth science and prepare for tests. Take a fascinating journey to the Super Science Station to learn about types of rock.
