Which of the following is NOT true about the geosphere?
It includes all rock material on Earth.
It is made up entirely of solid material.
It contains iron, magnesium, and oxygen.
It is made up of the crust, mantle, and core.
Which of the following describes the Earth’s mantle?
It is the thinnest, coolest layer of the geosphere.
It is the densest, innermost layer of the geosphere.
It is the hot, solid, middle layer of the geosphere.
It is the least dense, outermost layer of the geosphere.
When objects transfer energy through touch, that process is called _______.
radiation
convection
conduction
densification
If a foam block floats in a container of syrup but a lead weight sinks, which is the LEAST dense material?
foam
syrup
lead
The materials are equally dense.
What is magma?
any volcanic rock
any rock in the core
solid rock inside the Earth
liquid rock inside the Earth
Which is NOT a process in a convection cell in the mantle?
Cooler, denser rock sinks due to gravity.
The rock cools as it approaches the core.
Hotter, less dense rock rises towards the crust.
The rock is cooled through proximity to the crust.
The hydrosphere is _______ salt water.
losing
only 3%
about half
mostly made up of
Which of these is an example of radiation?
Solar energy heats up water in the shallows of a lake.
Wind gathers warm water vapor from the ocean surface.
Geothermal vents on the ocean floor heat up the surrounding water.
A current coming from the equator brings warm waters to the poles.
The sun provides ________ the Earth’s interior to the hydrosphere.
less energy than
more energy than
as much energy as
a negligible amount of energy when compared to
Deep currents are __________.
not cold. Surface currents are cold.
cold because cold water is denser than warm water so it sinks.
cold because the water becomes cold after it sinks due to conduction.
cold because cold water is less dense than warm water so it sinks.
What is NOT included in the atmosphere?
space
Water Vapor
the air you breathe
where weather happens
What matter is cycled in the atmosphere?
birds
solar energy
air particles
convection cells
Which of the following is an example of how gravity affects weather?
Solar energy heats water.
Water evaporates and rises as it heats.
Cloud droplets fall to the surface as rain or snow.
Water vapor cools and condenses into cloud droplets.
How is most matter and energy cycled in the biosphere?
food chains
convection cells
conduction cells
radiation chains
Where does energy originate from in the biosphere?
the sun
producers
herbivores
decomposers
In the biosphere’s cycle of energy and matter, decomposers gain energy/nutrients from ________ and give energy/nutrients to __________.
radiation from the sun; herbivores
recycling dead organisms; producers
eating plants and animals; carnivores
eating plants; herbivores and carnivores
An example of a small scale change is __________
a landslide covering houses in mud.
a volcano erupting and depositing lava around it.
a wave rubbing sand against a rock, weathering it.
an earthquake causing a cliff to fall into the ocean.
When rock is broken down in place it is called _________, but if material is removed, it is called _________.
weathering; erosion
breaking; transportation
sanding; sedimentation
reacting; deposition
How are sand dunes formed?
Eroded sand is carried by the wind and deposited.
A large flood leaves the sand behind in wave shapes.
Beetles walk across the sand and it forms big ripples.
The ground beneath the dunes is already shaped like hills.
Mountain ranges are formed over hundreds of millions of years through the process of _________.
uplift
erosion
deposition
weathering
Sandstone is formed by __________.
chemical weathering of limestone
uplift of deep crustal rock to the surface
stone being eroded by sand over millions of years
sand being deposited in layers that are compacted together
Limestone caves are formed through the process of __________ when a chemical reaction causes the limestone to dissolve into water.
erosion
deposition
chemical weathering
mechanical weathering
What is the difference between magma and lava?
There is no difference.
Magma is solid rock and lava is molten rock.
Magma is molten rock and lava is solid rock.
Magma is below ground and lava is above ground.
