Earth
Scientists Say: Tectonic Plate
Tectonic plates are giant slabs of rock that make up Earth’s outer layer.
HS-ESS2-1
Develop a model to illustrate how Earth's internal and surface processes operate at different spatial and temporal scales to form continental and ocean-floor features.

Explainer: What is friction?
The force of friction always acts to slow things down. It depends on just two factors: the surfaces and how hard they press together.

Uplifting Antarctic shores point to accelerating loss of glaciers
It appears the Pine Island and “Doomsday” Thwaites glaciers are losing ice — and shrinking faster — than at any time in the past 5,500 years.

Let’s learn about diamond
Diamond is born under extreme heat and pressure inside Earth and elsewhere in the universe.

Scientists Say: Fault
A fault is a crack in Earth’s crust where pieces of rock scrape past each other.

Tiny gemstones show when Earth’s crust first started moving
Chemical hints observed in zircons suggest when the important process of plate tectonics first took off.

Scientists Say: Richter Scale
The Richter scale and other magnitude measures reveal the strength of an earthquake.

Volcanic avalanches may be more destructive than previously thought
Pressures within these pyroclastic flows may be as much as three times as high as observations had suggested.

The ‘Doomsday’ glacier may soon trigger a dramatic sea-level rise
The ice shelf that had kept it in place could fail within five years. That would speed the glacier’s slip into the ocean, boosting a rise in sea levels.

Scientists Say: Avalanche
The word avalanche usually refers to a huge snowslide down a mountain, but it can also be used to describe any large mass of material tumbling downhill.
