"Compare the first and third quarter of the moon cycle as seen from the Northern Hemisphere. You must discuss the relative positions of the sun, moon, and earth in your response"
Answer:
The Third Quarter Moon is when the opposite half of the Moon is illuminated compared to the First Quarter. Which half you see lit up depends on where you are on Earth. Only 50% of the Moon is illuminated during its third quarter phase.

Answer:
The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
Geologic time, the extensive interval of time occupied by the geologic history of Earth. ... Modern geologic time scales additionally often include the Hadean Eon, which is an informal interval that extends from about 4.6 billion years ago (corresponding to Earth's initial formation) to 4.0 billion years ago.
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water known as a shelf sea. Much of these shelves has been exposed during glacial periods and interglacial periods. The shelf surrounding an island is known as an insular shelf.

Scientists would like to learn more about the seismic activity that occurs on Earth’s surface. They are set to take a journey to the deepest part of earth. Develop 4 questions they should ask before they take this journey. Be sure to anticipate the factors that will change as they travel from the surface of Earth towards the core. ( giving brainliest)
Answer:
the questions they could ask would be:
how much will the temperature change?
how much pressure will there be?
how durable does the equipment need to be?
how do we know if we will run into a water pocket or a magma pocket?
Explanation:
what do i wright: You are a drop of water going through the water cycle. Where do you go? How do you get there? What processes do you go through? Include at least three phases of the water cycle , i know the phases of the water cycle
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
three phases of water cycle are
evaporation, condensation, precipitation

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?
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.

Mechanical advantage of a ramp is simply defined as the ratio of the length of the ramp to the height of the ramp. Mathematically, it is given by:Mechanical Advantage = Lenght / height MA= L/H With the above formula, we can obtain the mechanical advantage of the ramp as follow:Length (L) of ramp = 4 mHeight (H) of ramp = 1.5 mMechanical advantage (MA) of ramp =?MA = 4/1.5MA = 2.7Therefore, the mechanical advantage of the ramp is 2.7

BTW ITS A SCI QUESTION
Answer:
Net force
I think it’s balanced force
Explain the relationship between mass and gravity
Answer:
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
Explanation:
i did some research and this is what I got. hope it helps.
Mass is the amount of matter present in an object. All objects in the universe attract every other object in the universe. This force is called the gravitational force or gravity. This force is proportional to the product of the masses of the two objects and inversely proportional to the square of distance between them.
More is the mass, more is the gravitational force or gravity
Can someone help me with this science question

1. The Earth's inner core is actually pretty wide, and big.
2. The surface spins way faster than Earth's surface.
3. The inner core is the hottest area on Earth.
4. Although the inner core is made out of Nickel, it's mostly Iron. (85% Iron 15% Nickel)

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.
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.

Answer:
Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.
Explanation:
Write down one fact about each of the following crust, mantle, outer, core, & inner core
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.

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
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.
