Geology on Mars
What are the four spheres that makes up Earth and Mars?
hydrosphere, atmosphere, biosphere, and geosphere
the shape of the illuminated part of the Moon as it appears from Earth is called
moon phases
Define force
a push or a pull that can change the motion of an object
Draw two magnets representing attraction
N - S and N-S
S - N and S - N
a type of wave that carries energy from one place to another, even through empty space
Define geologic process
an event or series of events that causes changes in the geosphere, such as flowing water or flowing lava
Define the terminator (scientifically)
the border between light and dark on the Moon
a force between an object and the surface it is moving over is called
friction
False. Aluminum is not attracted to magnets.
What causes skin cancer?
Ultaviolet light
T/F. Scientists believe Mars could be Earth's next habitable planet.
True.
The complete cycle of moon phases, also known as a lunation, takes approximately
30 days
What is the difference between speed and velocity?
speed is how fast an object is moving
velocity is speed in a particular direction
The tool used to support and guide during times of geomagnetic activities
a compass
How are transmit, emit, absorb, and reflect related?
transmit: light energy traveling
emit: give off the light energy
absorb: some light energy enter materials
reflect: some light energy do not enter materials
How are landforms used as evidence?
Landforms can provide evidence about the past because they remain after the geologic processes that formed them stop happening.
Which claim is true:
1. The Moon’s appearance changes because Earth casts a shadow on the Moon.
2. The Moon’s appearance changes because the position of the Moon changes.
2. The Moon’s appearance changes because the position of the Moon changes.
Every action will lead to an opposite or equal reaction.
Newton's 3rd Law
Bouncing on a trampoline. Where are the points of potential energy?
1. briefly landing on the trampoline
2. briefly at the highest point before going back down
Which wavelength is stronger: radio or gamma ray
gamma ray
What two events cause channels?
Flowing water and flowing lava can create channels.
What is the difference between lunar and solar eclipse?
Lunar eclipses happens when the Earth passes between the Sun and Moon (casting a shadow on the Moon) while a solar eclipse occurs when the Moon passes between the Sun and Earth (casting a shadow on Earth)
Newton's law of inertia
1st Law: An object at rest will stay at rest unless acted upon an outside force.
How does kinetic energy and potential energy play a role in the system of magnets?
kinetic energy is generated when potential energy stored in the magnetic field is converted into the motion of the magnets themselves
Name at least 6 types of light
gamma ray, x-ray, ultraviolet, visible, infrared, microwave, radio
