Structure of the Earth: the story of the waves

A 20 minute lesson where students interpret a graph showing how the velocities of P- and S-waves change with depth in the Earth, Two tables summarize the properties of seismic waves and layers of the Earth. Links are provided for printable teacher notes and student's material. From the Joint Earth Science Education Inititive and the excercise from the Earth Science Teachr's Association series of teaching materials.

What Will Happen When Earth's Plates Stop? | @NatGeo | #platetectonics

A 2018 study suggests the mantle will cool to such an extent that the plates will grind to a halt in 1.45 billion years--changing life on Earth as we know it.

#Dinosaurs Roar Again, Now Including a Focus on #ClimateChange | @AGU_Eos | #fossils #DeepTime

An article introducing the newly renovated fossil hall at the Smithsonian's National Museum of Natural History that features spectacular fossils and includes a theme of human impact on life on Earth. The article includes a sneak peek video and sections on: the Koch gift, transformation of the hall, and the human connection to the exhibit.
