crust and consists of Basalt? ---------CORRECT ANSWER-----------------
Oceanic
Which type of plate is thicker on land and contains Granite? ---------
CORRECT ANSWER-----------------Continental
What is the thickest layer of Earth? ---------CORRECT ANSWER---------------
--The Mantle
What percentage of Earth's volume does the Mantle make up? ---------
CORRECT ANSWER-----------------84%
_____________ extends from where the crust ends; sticky but formed from
rock which is also known as peridotite. ---------CORRECT ANSWER----------
-------Upper Mantle
,__________________ extends from the upper mantle and made up of
magnesium. ---------CORRECT ANSWER-----------------Lower Mantle
Made of two parts and is known as the innermost part of the Earth ---------
CORRECT ANSWER-----------------Core
____________________: solid; temperatures and pressures are extreme;
rotates faster within the outer molten core ---------CORRECT ANSWER------
-----------Inner Core
______________________: solid; 6,000 ft below; made of Iron; low
viscosity but certainly not liquid; malleable ---------CORRECT ANSWER-----
------------Outer Core
This is known as the solid, outer part of Earth's surface and includes the
tectonic plates ---------CORRECT ANSWER-----------------Lithosphere
The layer of gasses that surround the Earth is known as the
___________________. ---------CORRECT ANSWER-----------------
Atmosphere
______________________: the lowest layer of the atmosphere that
contains the weather. It gets colder as you go up and makes up 80% of
Earth's atmosphere. ---------CORRECT ANSWER-----------------Troposphere
,__________________________: the temperature gets warmer as you go
up in this layer. This is known as the Ozone layer and protects against UV
rays. ---------CORRECT ANSWER-----------------Stratosphere
Your class observes a penny underwater and notices that an object
underwater appears to be closer to the water's surface than it really is. How
do you explain this to the class? ---------CORRECT ANSWER-----------------
Light bends as it travels from one substance to another (water to air). This
change in the path of the light wave makes the penny appear closer to the
surface than it really is.
To demonstrate the Doppler effect, you ask a student to stand still. You tell
the student that you will play music from your phone walking toward him
first and then you will hold the phone out as you walk in a circle around
him. Will the sound increase coming toward him or in a circle? ---------
CORRECT ANSWER-----------------The student will perceive an increase in
the sound's pitch if the teacher walks toward the student
As the source of the sound moves toward the student, each step closer
(successive sound wave) will start at a point closer to the student resulting
in the sound waves reaching the student with increasing frequency.
Because the frequency of the sound waves increase, the student perceives
an increase in the sound's pitch.
Individual molecules in liquid water are different than molecules in water
vapor because... ---------CORRECT ANSWER-----------------They are further
apart
You instruct students to fill two of the exact same containers with the same
amount of freshwater and saltwater. You then ask them to place different
items into the same containers and write in their notebooks about which
items sank and which items floated. What OBSERVATION should students
, make if an object sank in freshwater but floated in salt water? ---------
CORRECT ANSWER-----------------The salt water was DENSER than the
freshwater.
An object will sink in a liquid if its DENSITY is greater. An object will float if
its DENSITY is less than OR equal to that of the liquid. The student should
CONCLUDE that the salt water is DENSER than BOTH the object AND the
freshwater.
You instruct students to:
1. soak steel wool in vinegar for 1 minute
2. remove the steel wool from the vinegar
3. squeeze the steel wool and blot it with a paper towel
4. wrap the steel wool around the bulb of a thermometer
5. place the steel wool and thermometer together in a covered beaker to
allow the rusting process to happen
6. observe the temperature reading of the thermometer increase slowly
What would be an example of a students' OBSERVATION? A reaction
occurred in which:
A. Energy was created
B. Energy was destroyed
C. Energy was evaporated
D. Energy was released ---------CORRECT ANSWER-----------------D. A
reaction occurred in which energy was released.
A temperature increase shows that energy was released into the
surroundings. Soaking steel wool in vinegar removes a protective coating
on steel wool. This exposes the iron in the wool to oxygen in the air. Iron
and oxygen in the presence of water produces rust, which releases heat
energy.
Look here! You tell students as you rub an inflated balloon with a wool cloth
and hold the balloon over torn up pieces of paper on a table. Students
watch as the bits of paper rise up toward the balloon. What HYPOTHESIS
