Earths Landforms
A physical feature of earth's surface
What is a landform?
When plates slide past eachother they create
What is shear?
A
What is a crater
Earthquakes occur near
What are the boundaries of tectonic plates?
particles carried along in the river.
What is sediment?
An opening in the earth's crust out of which magma flows.
What is a volcano?
A scientist who studies the earth's structure and history.
What is a geologist?
An opening in the earth's crust where magma flows
What is a volcano?
Where the plates slip or collide.
What is the focus?
The process where weathered rock is moved from one place to another.
What is erosion?
Two measurement tools used to measure the magnitude of an earthquake
What is a Richter scale and a seismometer?
Plates that collide or crash into eachother are called.
What are colliding or convergent plates?
A stationary pool of magma below the earth's crust.
What is a hotspot?
Where people actually start feeling the shakes of an earthquake.
What is the epicenter?
Describe the difference between physical weathering and chemical weathering.
Physical weathering is caused by the natural and temperature changes.
Chemical weathering is caused by the chemicals in the groundwater.
The highest landform on land and in the ocean
What are mountains and sea mounts?
The Himalayas mountains are what type of mountains.
What are folded mountains?
A series of volcanic islands that form along the plate boundaries
What is an island arc?
An underwater earthquake
What is a tsunami?
The processes that break down and build up land.
What is weathering and erosion are the break down processes and deposition is the build up of land.
Describe the layers of our earth.
Earth's water is in the hydrosphere. The gases are in the atmosphere. The mantle is made up of solid and liquid rock and the core is made up of solid and liquid metals. We live in the Biosphere. Solid pieces of rock rest on the hot, soft, slippery rock of earths asthenosphere.
Explain the continental drift theory.
The continental drift theory was developed by Alfred Wegener. he believed that our continents that have separated were once one large continent known as the "super continent" or the Pangea. Wegener proved his theory with fossils and other evidence proving what once may have been on a continent is no longer existent in the areas during later years.
Explain the three types of volcanoes.
A shield volcano is a volcano with sloped sides formed from thin fluid lava.
A cinder cone volcano is a cone shaped volcano with a narrow base and steep sides.
Composite volcano is built from layers of cinders and hardened lava.Which scale would better explain the magnitude of an earthquake and why?
What is the Mercelli scale because it is newer and more advanced making it more accurate.
Steps to prevent waves from eroding a beach
What is find the cause of erosion and build levees, grasses, and fences.
