Earth's Surface
Weathering & Layers
100
A mountain with an opening in the crust through which lava flows.
What is a volcano?
100
A shaking of ground from energy release in the crust.
What is an earthquake?
100
Hot, soft rock from the lower mantle.
What is magma?
100
A rigid block of crust and upper-mantle rock.
What is a plate?
100
Name any landform wind erosion can create.
Arches, tables, columns, dunes, etc.
200
Remains or traces of past life found in sedimentary rock in the crust.
What are fossils?
200
Physical features on Earth's surface.
What are landforms?
200
The theory of how continents move over Earth's surface.
What is continental drift?
200
Name the three ways Earth's plates interact.
They collide, pull apart, and scrape & slide against one another.
200
Name any way water can weather rock.
Acid rain can dissolve rock, water can push rocks into other rocks which breaks them apart, water can get into cracks and holes then freeze and expand which breaks them apart, etc.
300
The downhill shifting of rock and soil caused by gravity.
What is mass movement?
300
The process in which rock is broken down into soil, sand, and sediment.
What is weathering?
300
The process of moving sediment from one place to another.
What is erosion?
300
How are most of the highest mountains formed?
When continental plates collide.
300
If the center of the Earth is the hottest, why is it solid instead of melted liquid rock?
Because of the great pressure at the center of the Earth.
400
The center and hottest layer of the Earth.
What is the core?
400
The "supercontinent" on Earth millions of years ago.
What is Pangea?
400
The outer, very thin layer of Earth.
What is the crust?
400
Describe a way a volcano is formed (you must be more specific than saying by lava and ash).
Oceanic and continental plates collide, oceanic plate dips into mantle and melts, then magma comes up; plates move over hot spot in mantle and melt a hole in the plate, magma rises up through the hole, etc.
400
How is it possible for Earth's plates to move?
Because they float on the soft rock of the mantle, which has currents like water.
500
The process of dropping sediment in a new location.
What is deposition?
500
The middle layer of Earth.
What is the mantle?
500
A place where pieces of the crust move.
What is a fault?
500
Name all three kinds of volcanoes (NOT names of specific volcanoes).
Shield, cinder cone, composite.
500
Describe how Earth's surface is changing right now - how are the continents moving?
The Atlantic Ocean is getting wider, pushing Europe and North America apart, the Pacific Ocean is getting smaller, Australia is moving north.
