what is a tsunami
A tsunami is a series of large ocean waves caused by underwater earthquakes volcanic eruptions or landslides
What facts explain why tsunamis become taller near shore?
As the waves move into shallow water, wave shoaling causes them to slow down and grow taller
How does mass affect the gravitational force between two objects?
The greater the mass of the objects, the stronger the gravitational force between them.
How can you determine if forces on an object are balanced or unbalanced?
Add all the forces to find the net force. If the net force is 0 N the forces are balanced If it is not 0 N the forces are unbalanced
How might Yellowstone National Park change if the Sulfolobus microorganisms disappeared
The hot springs would likely become less acidic because Sulfolobus helps produce acids in the water. This could affect the organisms that live in those environments
When do tsunamis usually occur?
Tsunamis usually occur after an underwater earthquake or other disturbance that moves a large amount of water
What is convection
Convection is the movement of heat through a fluid, such as the mantle, where hot material rises and cool material sinks.
How does distance affect gravity between two objects?
As distance increases, gravitational force decreases.
How do red shift and blue shift help astronomers determine a star's motion
Red shift means a star is moving away from Earth while blue shift means it is moving toward Earth
If an element had a different number of protons, how would that affect its position on the Periodic Table?
It would become a different element because the number of protons determines the atomic number and identity of an element.
How would you show the inside of the Earth?
I would draw and label the crust mantle outer core and inner core showing that temperature and density increase toward the center
Which one involves one plate sinking beneath another
Subduction at a convergent boundary
How does inertia change when the mass of an object changes
As mass increases, inertia increases. Objects with more mass resist changes in motion more
How did Edwin Hubble's discoveries change our understanding of the universe
He discovered that galaxies exist outside the Milky Way and that the universe is expanding because galaxies are moving away from each other
Why do scientists need to understand chemical and physical changes when studying Yellowstone's thermal features?
Understanding these changes helps explain how minerals dissolve react and form new substances in hot springs and geyser
Who was responsible for developing the theory of plate tectonics?
Many scientists contributed but Alfred Wegener helped lay the foundation with the idea of continental drift
Which one is the densest layer of Earth?
the core is the densest layer of earth
How does a net force affect an object's acceleration
A greater net force causes greater acceleration in the direction of the force.
How does the Cosmic Microwave Background support the Big Bang Theory?
It is leftover radiation from the early universe and provides evidence that the universe began in a hot dense state and has been expanding ever since.
Why is binary code important for sending pictures through apps like Snapchat?
Binary code allows images to be converted into digital information that computers and phones can process and transmit.
Which is the best answer for a boundary where plates move apart
A divergent boundary
How would you classify a boundary where plates slide past each other?
a transform boundary
How are force mass and acceleration related
They are related by Newton's Second Law: F = ma Force increases when mass or acceleration increases
How does the Doppler Effect help scientists study stars and galaxies?
The Doppler Effect changes the wavelengths of light allowing scientists to determine whether objects are moving toward or away from Earth
How would a camera be affected if the photoelectric effect did not occur?
Cameras would not be able to convert light into electrical signals making digital photography impossible.
