1. How is the Moon cycle an example of the sun, moon and earth interacting?
2. Why does the moon appear completely dark once a month?
Answers
Answer:
The moon orbits the earth because of the pull of the earth and so does the earth orbits the sun because of its pull. Because of the way they move relative to each other, we see phases of the moon and eclipses.
The moon appear completely dark once a month because at that time of the month, the moon passes through the same part of the sky, with it's dark or unilluminated side faces Earth.

Explanation:
In a computer simulation, Juan moves a magnet (Magnet 1) closer to another magnet (Magnet 2) that cannot move. Which statement accurately describes the change in potential energy?
a
The potential energy does not change because the magnets in the system do not change.
b
The potential energy increases because Magnet 1 moves against the magnetic force.
c
The potential energy decreases because Magnet 1 moves against the magnetic force.
d
The potential energy decreases because Magnet 1 moves in the same direction a
Answers
Answer:
C
Explanation:
The potential energy decreases because Magnet 1 moves against the magnetic force. If it was increased it would be kinetic
When Magnet 1 moves against the magnetic force, the potential energy will increase.
Potential energy:
It is the enregy of present in the object or system due to the position of the different parts of the system.
Here, when one magnet bring closer to another magnet the magnetic force will increase.
Therefore, when Magnet 1 moves against the magnetic force, the potential energy will increase.

Answer:
1. nuclear waste
radioactive waste material, for example from the use or reprocessing of nuclear fuel.
2. crust
In geology, the crust is the outermost solid shell of a rocky planet
3. mantle
A mantle is a layer inside a planetary body bounded below by a core and above by a crust.
4. core
Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km, which is about 20% of Earth's radius
Explanation:
Answer:
Nuclear Waste :- Nuclear waste is the material left over in the reactor. This waste is radioactive and needs to be stored safely away from humans because it is dangerous and toxic to living things.
The Crust:- the crust is the outermost solid shell of a rocky planet, dwarf planet, or natural satellite. It is usually distinguished from the underlying mantle by its chemical makeup; however, in the case of icy satellites, it may be distinguished based on its phase.
Mantle:- A mantle is a layer inside a planetary body bounded below by a core and above by a crust. Mantles are made of rock or ices, and are generally the largest and most massive layer of the planetary body. Mantles are characteristic of planetary bodies that have undergone differentiation by density
Inner and outer core:- outer core is the third layer of the Earth. Earth's inner core is the innermost geologic layer of the planet Earth.
Lithosphere:- lithosphere is the rigid, outermost shell of a terrestrial-type planet or natural satellite
Geological Time:- geological time, the extensive interval of time occupied by the geologic history of Earth.
Cherise sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Cherise can move the carts one space to the left or one space to the right. Which movement will result in the largest increase in potential energy?
a
Moving the cart on Track 1 one space to the right (→).
b
Moving the cart on Track 2 one space to the left (←).
c
Moving the cart on Track 2 one space to the right (→).
d
All these movements will result in the same change in potential energy because they each move a cart the same distance.
Answers
Answer:
it's d
Explanation:
The movement that will result in the largest increase in potential energy is D. these movements will result in the same change in potential energy because they each move a cart the same distance.
Potential energy refers to the energy that's possessed by a body when it's at rest. Kinetic energy is the energy that's based on the motion of an object.
In this case, we can see that the carts are moved one space either to the right or left. Therefore, the movements will result in the same change in potential energy.

Answers
Explanation:
As the Sun heats the ocean, the water evaporates, turning into a gas. Sometimes this gas meets cooler air, and the gas changes into drops of water. This process is called condensation. Drops of water fall back down to Earth again as precipitation, which can be in the form of rain, snow, sleet, or hail

Write down one fact about each of the following crust, mantle, outer, core, & inner core
Answers
Answer:
Hope this help you!!
Explanation:
Crust : The crust is the thinnest layer of the Earth. It has an average thickness of about 18 miles below land, and around 6 miles below the oceans. The crust is the layer that makes up the Earth's surface and it lies on top of a harder layer, called the mantle.
Mantle : The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 1,802 miles thick, and makes up a whopping 84% of Earth's total volume
Outer Core : The outer core is the third layer of the Earth. It is the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances. The outer core is responsible for Earth's magnetic field. As Earth spins on its axis, the iron inside the liquid outer core moves around.
Inner Core : It's Almost The Size of the Moon. The Earth's inner core is surprisingly large, measuring 1,516 miles across. It's Mostly Made of Iron. It Spins Faster Than the Surface of the Earth. It Creates a Magnetic Field.
