Question | Answer |
---|---|
magma | hot molten rock |
Lithosphere- | The crust and upper area of the mantle |
Plate- | large pieces of pieces of the lithosphere. |
Theory of Plate Tectonics- | The idea of the Earth's crust is made of moving plates. |
Plate Boundary- | Places where the plates meet. |
Earthquake- | Rocks along the plate boundaries that shift suddenly and release stored energy. |
Fault- | Breaks in the Earth's surface along which rocks can move. |
Epicenter- | The point on the surface of the Earth directly above the focus. |
Magnitude- | The strength of the seismic waves of an earthquake. |
Richter Scale- | A machine that detects, times, and measures the movements of the Earth. |
Seismograph- | Measures the magnitude of an earthquake. |
Tsunamis- | Giant ocean waves triggered by earthquakes, volcanoes,or landslides. |
Focus- | Beginning point of an earthquake. |
Seismic Waves- | Vibrations that flow out from the beginning point of an earthquake. |
Magma- | Molten rock. |
Volcano- | Forms where a crack in the Earth's crust allows magma and gases to come to the surface. |
Volcanologist- | Scientists who study volcanos. |
Magma Charter- | Deep in the Earth's lithosphere,pockets of molten rocks. |
Lava- | When magma cracks the Earth's surface. |
Vent- . | Where the lava flows out of |
Crater- | The bowl shape at the top of the main vent. |
Ash- | When a volcano erupts it produces clouds filled with jagged bits of crushed rock. |
Cone- | A funnel shaped mound. |
Ring of Fire- | Rings that volcanoes form. |
Hot Spot- | Places where a pool of intensely hot magma rises toward the surface. |
Cinder- | Eruptions tend to be explosive, which send ash and lava floating in to the air. |
Tephra- | Hardened lava. |
Pyroclastic Flow- | Red hot dust and gases. |
Vog- | Volcanic gases. |
Debris Flow- | Occurs when part of the mountain collapses and mud and rock fragments surge down the mountain. |
Igneous Rock- | When magma and lava harden it forms rocks called Igneous Rocks. |
Hot Spring- | When the water is heated and it rises to the earths surface. |
Geyser- | A hot spring that periodically blows steam and hot water into the air. |
Mud Pot- | A hot spring that contains more mud than water. |
