Plate Tectonics/Seismic Waves 2026-01-09
Across
- discovered the theory of continental drift using geologic, fossil, and glacial evidence; theorized that Pangaea once existed and all of the continents drifted apart
- the area of Earth where neither P-waves nor S-waves are detected on a seismograph after an earthquake has occurred; due to the S-waves inability to travel through the liquid outer core and the P-waves being refracted by it
- supercontinent which showed all of Earth’s landmasses were once joined together 245 million years ago
- theory that continents can drift apart from one another and have done so in the past
- waves of energy that travel through the Earth; defined as either body or surface waves
Down
- The theory that the Earth’s lithosphere is divided into tectonic plates that move around on top of the asthenosphere
- when seismic waves hit a boundary between different materials and pass through, their speed is changed and their path is bent
- type of body wave (can travel through the earth); second to arrive to a seismograph after an earthquake; can travel through solids and gases, but not liquids
- when seismic waves hit a boundary between different materials and bounce off the material
9 Clues: theory that continents can drift apart from one another and have done so in the past • waves of energy that travel through the Earth; defined as either body or surface waves • when seismic waves hit a boundary between different materials and bounce off the material • ...
