What is the difference between mass and weight?
Mass stays the same; weight changes with gravity
The Earth _________ on its axis at a 23.5 degree tilt
Rotates
The heat from the __________ drives the water cycle. Water vapor evaporates into the air. Water comes down as rain. Ponds and lakes are reservoirs. Living organisms use water. Then the cycle starts again.
Sun
What does a scientific law do?
Describes what happens.
The variable that is manipulated.
The independent variable
True or false:
Energy and matter are not created or destroyed..they are just converted to other forms.
True.
The Earth is a closed system (think of a terrarium).
Ex. The total amount of Carbon remains the same, it is just converted to different types of molecules. Photosynthesis and Cellular Respiration are a good example of this.
Order of space (largest → smallest)?
Universe → Galaxy → Solar System → Star → Planet → Moon
In electromagnetic waves: as wavelength increases, frequency ___________________--
Decreases
The process within organisms that keeps balance within its cells and all of its' systems.
Homeostasis.
True or False:
If a part of a theory is found not to be accurate, we throw out the entire theory?
False.
Theories are adjusted and new information is added.
The moon ______________ around the Earth
Revolves
Which body system is responsible for sensations such as pain?
Nervous system
This type of wave travels fastest in a solid medium.
Sound wave
True or False:
Not all scientific knowledge is derived from experiments.
True
Relationship where both organisms benefit.
Mutualism
When two of earths tectonic plates move alongside of each other, they are called:
Transform Plates
(The other two types of plates are convergent and divergent)
The model that places the sun at the center of the solar system?
Heliocentric
A _________ wave travels fastest in a vacuum.
Electromagnetic wave. Like Light.
Heat is a form of energy. We can measure heat by measuring molecular movement. The faster the molecules, the higher the _________________ of the substance. We use a thermometer to measure this molecular movement.
temperature
True or False:
Many physical properties of matter can be demonstrated or measured independent of sample size.True.
True or false: And explain
In an atom: The nucleus occupies very little of an atoms volume but contains most of its mass.
True. Protons and neutrons are the largest subatomic particles and are both found in the nucleus. Electrons are tiny compared to protons and neutrons and they move around the protons and neutrons at a distance.
This type of rock is created within the Earth under extreme heat and pressure.
Metamorphic.
It often looks wavy because it gets melted and crushed.
This type of wavelength has the greatest frequency
Gamma rays
Maintaining stable internal conditions.
homeostasis
Heat transfer always goes from a ______________ substance to a ____________ substance.
Hotter to colder
What is the law that says: In layers of sedimentary rock, the oldest layer is at the bottom? If you find a fossil within a layer of sedimentary rock, that organism existed at the time that layer was put down.
Law of superposition
Which holds heat longer? Water or land?
Water holds heat much longer than land does. The heat held in the oceans helps to regulate the temperatures here on Earth.
What do plant cells have that animal cells do not have?
*Cell Wall
*Chloroplasts
*Large Central Vacuole
In Linnean classification the last two levels of classification are italicized. What are the last two levels.
Genus Species
We get one set of this genetic material from each of our parents.
Genes or DNA or Chromosomes
A red star and a blue star are the same size. Which one is hottest?
The blue star.
Red stars are cooler than blue stars.
How does increased combustion affect the carbon cycle?
It increases carbon dioxide in the atmosphere
A rock is broken into sand, carried by water, and later compressed into rock again. Identify ALL three processes.
weathering → erosion → deposition
If sodium (Na) and potassium (K) react similarly, what can you infer about their placement on the periodic table?
They are in the same group/column
During cellular respiration, glucose and oxygen are converted into what?
Energy, CO2, and water
