A boundary where two tectonic plates come together, or collides, is called a
divergent boundary
convergent boundary
transform boundary
transfer boundary
Earth's core is mainly composed of
iron and aluminum.
silicon and hydrogen.
iron and nickel.
silicon and oxygen.
Scientists believe the Earth's inner core to be solid. This is probably due to extremes in
depth.
density.
temperature.
pressure.
Which of the following is an agent of chemical weathering?
acid rain
freezing and thawing.
tree roots growing through roots.
rocks tumbling down a stream or river
What makes up soil?
only weathered rock
only organic rock
only animals and plants
weathered rock and organic matter
A drawing of the Ring of Fire is a model that helps scientists predict areas where
hurricanes are likely to occur.

ocean currents are likely to occur.
thunderstorms are likely to occur.
Which is an example of a landslide?
mining
erosion
logging
farming
What can fossils reveal about Earth's past?
only changes in Earth's climates over time.
changes in Earth's climates and surface features over time.
only changes in Earth's surface features over time.
present climates and surface features of Earth.
What was Wegener's hypothesis?
Today's continents were once part of a single land mass that split apart.
The continents are made of rock.
The continents have always been where they are now.
The continents will one day join to form a single continent.
What features of Earth are produced by the movement of lithospheric plates?
solid masses of iron and nickel

Which BEST explains why soil is such an important resource?
Soil is used to grow the world's food crops.
Soil is packed together to make bedrock.

About how many years does it take to change flat land into a very deep canyon like the Grand Canyon?
10-20 years
hundreds of years
thousands of years
millions of years
The ability of water and air to pass through soil particles is called
acidity.
weathering.
permeability.
erosion.
Which is an example of chemical weathering?
Water freezing and expanding in cracks in rocks and pushing the rock apart.
Waves wearing away rocks on a beach.
Acid seeping into the ground and dissolving rock such as limestone.
Rock pieces carried by river water that weathers the rocks in a riverbed.
Deposition is a process that
dissolves sediment.
breaks down rock into smaller particles.
removes rock and particles from landforms.
drops sediment to form landforms.
What is weathering?
a type of climate
the transport of rock particles
the breaking down of rocks
the aging of rock
Pangaea was Wegener's name for
the places where plates met.
the landmass made up of all of the continents.
the process that moves Earth's plates.
the lithosphere.
Why is contour plowing important?
It adds nutrients to the soil.
It reduces erosion by water.
It removes pollutants from the soil.
It increases weathering of rock.
Which layer contains the most nutrients?
topsoil
bedrock
parent material
subsoil
What does erosion do?
It breaks down rock physically.
It moves broken pieces of rock.
It changes rock chemically.
It changes sediment into rock.
What is the chemical make up of a rock?
texture
composition
deposition

Why are dead weeds and stalks of the previous year's crop left in the ground?
to keep the soil from being too fertile
to reduce the number of seeds for next year's crop
to keep more organisms out of the soil
to retain moisture and hold the soil in place
How does sedimentary rock most likely form?
by magma cooling and slowly changing into solid rock
by heat and pressure creating separate layers of materials
by lava from volcanic eruptions cooling on Earth's surface
by sand and other materials being deposited and hardening over time
