GA Milestones Science Grade 5- Questions
and Answers
Deposition Process whereby soil and rock that is eroded from one location is deposited as
sediment in another location
Continental Drift The process of the continents slowly moving around the surface of the
Earth
Tectonic Plates Sections of the surface of Earth that move toward or away from each other
Trenches Found where faults are located under the ocean
Glaciers Sheets of very old ice the size of states that move along Earth's surface
Ridges Formed when tectonic plates collide and both push up. Can also be formed in
areas where magma from Earth's core pushes up between or through tectonic plates.
Magma Molten rock
Volcano A break in Earth's crust that lets magma come out from the mantle and onto
Earth's surface.
, Where Volcanoes are Found In the deep ocean and on Earth's surface
Lava Magma that breaks the Earth's crust. Is thrown out of volcanoes
Earthquakes Happen when tectonic plates suddenly slide around. The plates shake, and
the energy from that creates waves that echo through Earth
Tsunamis Happen when earthquakes happen underwater. The energy released by the
earthquake is transferred to the column of water above it and creates waves that travel away from
the area.
Beach Reclamation Reduces the effect of erosion on beaches. Accomplished by dredging
sand from the ocean floor and depositing it back on the beach.
Floods Can be controlled by building dams to hold back water
Levees Earthen walls along riverbanks to prevent rivers from going outside their banks
onto surrounding land.
Retention Ponds Slows down the runoff of rainwater into streams and rivers to reduce the
risk of flooding downstream
seismograph A tool used to predict and measure earthquakes, volcanic eruptions, and
tsumanis
