Landforms
What is the process called that builds up the Earth's surface?
Constructive process
What is the term for the breaking of Earth's crust into sediment?
Weathering
What theory describes the movement of giant plates of rock?
Plate tectonics theory
What instrument do scientists use to measure earthquakes?
Seismograph
What is a volcano?
A mountain formed by molten rock flowing through a crack in Earth's surface
Name one example of deposition.
Delta, Island, or Sand Dune.
What is the difference between mechanical and chemical weathering?
Mechanical weathering is physical breaking while chemical weathering changes rocks into new matter.
Name the 2 types of tectonic plates.
Continental and oceanic plates
What is the point on Earth's surface directly above an earthquake's focus?
Epicenter
What is the Ring of Fire?
A circle of volcanoes around the Pacific Ocean
What are the two types of constructive processes?
Deposition and volcanoes
What role do living things paly in weathering?
Biological weathering
What happens at converging boundaries?
The plates move toward each other causing uplift of subduction.
How is the strength of an earthquake measured?
Richter Scale
How can volcanoes be both constructive and destructive?
They build up land (constructive), but can also cause destruction when the erupt (destructive).
How do weathering contribute to landform changes?
It breaks down rocks into sediment.
Describe a slow destructive process.
Weathering
What fills the gaps at diverging boundaries?
Magma
What type of boundary is most likely to cause earthquakes?
Transform boundaries
What is lava?
It is the carrying away of sediment by wind, water, or ice. (Teacher checks example).
How do glaciers contribute to erosion?
They carry sediment as they move.
What is a fault?
A crack in the Earth's crust.
What are seismic waves?
Waves that shake and cause breaks in the Earth's crust
Describe one way a volcano can affect the Earth's surface.
They can create new landforms like islands or mountains.
