Total questions: 20
Worksheet time: 10mins
What is the layer made of hot solid material between the Earth's crust and its core?
The mantle
The crust
The inner core
The lithosphere
What is the lithosphere?
The middle part of the mantle
The soft layer of the mantle on which tectonic plates move
A layer of molten iron and nickel surrounding the Earth's inner core
The rigid outer part of the Earth, consisting of the crust and the upper mantle
What are convection currents?
Large moving plates beneath the Earth's surface
Where two continental plates meet face to face
The process by which soil and sediments are transported by wind, water, ice, or gravity from one place to another
Circular currents in the mantle caused by the heating of magma by the Earth's core
The hypothesis that states that the continents were once a single landmass, then separated and drifted to their current locations.
Plate Tectonics Theory
Continental Drift
Seafloor Spreading
Pangaea
What are the large movable plates beneath the Earth's surface?
Tectonic plates
Continental shelves
Magma chambers
Faults
Places where tectonic plates meet.
Subduction
Divergent
Collision
Transform
Places where tectonic plates slide past each other during their movement.
Distribution
Subduction
Divergent
Fault
What is mechanical weathering?
The process that breaks down rocks through chemical changes
A type of weathering in which rocks are physically broken into smaller pieces without undergoing any chemical change
The process by which wind, water, ice, or gravity moves soil and sediment from one place to another
When streams, rivers, and oceans cut through the land and erode soil and rocks, moving them to other places
Small, hard pieces of material that come from rocks or living organisms.
Mountain ridge
Outcrop
Sediment
Igneous rock
When streams, rivers, and oceans cut through land, erode soil and rocks, and transport them to other places.
Coastal erosion
Wind erosion
Water erosion
Glacial erosion
What is the definition of glacial erosion?
The movement of soil or rocks from one place to another due to the movement of ice in a glacier
The formation of rocks as a result of volcanic activity
The deposition of sediments by wind
The disintegration of rocks by chemical reactions
What is an ocean?
A large body of warm water
A large body of fresh water
A large body of ice

What is an isthmus?
A narrow strip of land connecting two larger land areas
A large body of water surrounded by land
A mountain range separating two valleys
A deep valley with steep sides
What are plains?
A piece of land surrounded by water
A high mountain range covered with snow
A narrow strip of land connecting two larger land areas
A wide area of flat land with few trees
A mountain with a flat top and steep sides.
Valley
Butte
Mesa
Plateau
What is a glacier?
A large mass of moving ice and snow on land
Water in its solid frozen form
A large body of salt water
A mountain formed by volcanic activity
An elevated landform with sloping sides and a rounded top.
Mountain
Valley
Hill
Plain
What is a ridge?
A deep and narrow valley with steep sides
A long and narrow series of hills or mountains
A wide and flat land area
A body of water surrounded by land
What is a saddle?
A flat area at the top of a hill
A steep slope face on a mountain
A dip or low point along a ridge
A narrow water channel between two land masses
A landform that resembles a valley, but is usually a less developed watercourse and typically does not have a flat floor.
Valley
Canyon
Draw
Delta
