The gradual breaking down of rock into
smaller pieces by water and wind is called
Weathering
The movement of weathered particles is
called
Erosion
Small particles of silt, sand, and soil are
called
Sediment
A large mountain of ice that gradually travels
downhill, changing the surface of the earth
as it goes, is called a
Glacier
When water gradually wears away rock
underground, this can form.
A cave (or a sinkhole)
The movement of the earth’s plates can
cause
Volcanoes and earthquakes
A mountain that forms as lava flows through
a crack in earth’s surface is a
Volcano
A type of volcano that is made of layers of
lava, rock and ash and erupts explosively
is a
Composite volcano or Stratovolcano
The shaking of earth’s surface due to the
movement of rock in the crust is
An earthquake
When great amounts of soil and rock slide
down a slope due to water and gravity or
an earthquake, it is called a
Landslide
When two of the earth’s plates meet,
sometimes the edges crush and fold. This
creates
A mountain chain (or mountains)
Are landforms usually created by the earth
changing rapidly or slowly?
Slowly
An area with higher land around it, and that
stretches between mountains or hills is a
Valley
The Grand Canyon in Colorado was caused
by
Water erosion
Two landforms caused by the movement of
sand and sediment are
Deltas and dunes
Naturally occurring materials that humans
can use for energy, building, growing
crops, etc. are
Natural resources
Natural resources that cannot be replaced
are called
Non-renewable resources
A type of soil that can be used to make
bricks and pottery is
Clay
Sources of energy, such as coal and oil, that
come from the remains of ancient oceans
or swampy forests are called
Fossil fuels
Two examples of hard rocks that can be
used for building, statues, etc, are
Granite and marble
Earth has three main layers. They are:
The crust, the mantle, and the core
The earth’s crust is broken into sections
called
Tectonic plates (or just plates)
Cracks in the earth’s crust are called
Faults
Melted rock within the earth is called
Magma
Scientists can predict earthquakes by using
an instrument called a
Seismograph
