the inference that earth's interior has an outer core and an inner core is based on studies of
earthquake wave data
hydrogen and oxygen are classified as
elements
Most of Earth's major earthquakes are caused by
faulting of rock in Earth's crust
which activity involves only a physical change?
grinding coffee beans
which property of a mineral is tested by scratching it on a glass plate?
hardness
a student added some sugar to a glass of water, but it did not dissolve quickly. what could the student do to increase the rate at which the sugar dissolves in the water?
heat the water
which change is the best example of a physical change?
ice cream melting
as water is heated, the motion of the water molecules will generally
increase
the relatively thin layer of rock at earth's surface is called the
lithosphere
the thin layer of rock on earth's surface
lithosphere
the thin layer of rock on the earth's surface is the
lithosphere
which earth layer contains convection currents that are believed to be responsible for the movement of earth's tectonic plates?
mantle
all living and nonliving material is composed of
matter
elements on the periodic table of elements are classified into categories such as
metals and nonmetals
what will form when sedimentary rock is exposed to heat and/or pressure
metamorphic rock
water (H2O) is not found on the periodic table of the elements because water is
a compound
under which conditions would a sugar cube dissolve most quickly when placed in a liter of water at room temperature?
a crushed sugar cube is added and the water is stirred
because copper is a metal, it is
a good conductor of heat
sound waves are not able to travel through
a vacuum (empty space)
A student viewing a cell with a microscope observes a cell wall, a cell membrane, and a nucleus. The presence of these structures indicates that the student is looking at a cell from a
carrot
which sequence identifies the levels of organization of body structures in a human structures in a human from the simplest to most complex.
cell, tissue, organ, organ system
The basic life functions of an organism are carried on by
cells
in which part of the plant cell does photosynthesis occur?
chloroplast
one function of the human excretory system is
moving substances to and from body cells
a student writes in a laboratory notebook: I placed a piece of iron in a beaker of water and the iron sank to the bottom of the beaker. What the student wrote in the laboratory notebook is an example of a(n)
observation
Which gas is transported by the circulatory system in humans and is used by cells during respiration to release energy stored in food?
oxygen
the spoon's broken appearance is caused by the light that is
refracted
Volcanic eruptions are caused primarily by the movement of
tectonic plates
how does the theory of plate tectonics explain the location of these fossils?
the continents were once joined together
scientists have discovered fossils of the same organisms in many different parts of the world. These fossils provide evidence that
the continents were once joined together
rocks are classified as sedimentary, metamorphic, or igneous on the basis of the
way the rocks were formed
which geologic process occurs when the acid in precipitation dissolves certain types of rock?
weathering
