During a chemical reaction, atoms are rearranged to form new atoms. However in the sun's core, the energy creation process changes the nuclei of atoms. This causes a small amount of the original atoms mass to be converted into a large amount of energy, different from a chemical reaction in which only a small amount of energy is created.
After the energy is created in the core, the layer outside of it moves by radiation from one particle to the next. In this way the energy slowly travels outwards to the surface
It travels to Earth through space as electromagnetic waves, another type of energy transfer known as radiation
The 11 year solar cycle is the cycle in which the Sun's magnetic field completely flips. So the north and south pole switch places on the sun. It also affects the activity on the surface of the Sun, like an increased amount of sunspots.
It changes the amount of energy that the Earth receives from the sun, which can disrupt radio communications.
The fusion between two hydrogen atoms produces one helium atom, so the hydrogen is decreasing while helium is increasing
Stars with more mass burn hotter and brighter than less massive stars because they have a higher gravitational contraction so they burn through their hydrogen fuel faster, being brighter and hotter.
More massive stars have a shorter life spans because they use up their hydrogen fuel at a faster rate to counteract the gravity pushing in on them.
The sun would burn much brighter and hotter than a star with less mass. However, the sun would burn out sooner and become a red giant, while the other star would keep burning.
A star with the mass 10 times greater than the sun would live a considerably shorter time than the sun, but burn much brighter and hotter.
nuclear fusion
radiation: transfer of energy through electromagnetic waves
convection: transfer of energy through the movement of particles within a liquid or gas
I would use images of the sun and each layer and another image of the earth and sun and how energy is transfered
Through radiation and convection
By electromagnetic waves
It increases and decreases based on the solar cycle
main sequence star, expand and cool to a red giant, shrink and heat up into white dwarf
It is a average sized star, so it doesn't have an extremely long life span, or a very short one either
It will begin to expand, cool down, and shine less bright as it gets older
It will have less and less hydrogen atoms
It will have less and less hydrogen to burn through
In the first model, I used images off of google to help visualize the different layers of the sun and their purpose. Then I used images of the sun and earth and the process of energy transfer between the two. In the second model, I only used an image of a stars life cycle and information on apex to explain the life cycle of the sun next to it. I think I incorporated evidence onto the model well by using thorough explanations for each step. For the first model, I think using a video would have been better to explain the transfer of energy and the different rotations. For the second model, I think more images would have made it better.
It effects sun's rising and setting aka night and day
Having enough room for everything that needs sunlight. For example, plants need sunlight to grow, so where would people and all the plants that we need for oxygen grow go too?
The earth revolves around the sun
There wouldn't really be seasons and there wouldn't be solar solstices because they rely on the revolution of the earth.
Each hemisphere would receive and equal amount of sunlight throughout the year
This is because the axis is tilted away from the sun
No it will be the opposite because the earth's axis will slowly rotate as well because of the effects of precession because
Crust

outer core
inner core
The deeper you go below the crust, the more rock is above being pulled by down gravity. This is what causes the pressure to increase similar to swimming to a bottom of a pool and that pressure, except it's with rocks.
As pressure increases on something, the melting point also increases. So despite the high temperatures, the immense amount of pressure from all the layers of rock keeps it from becoming liquid
It is hotter in the mantle than the crust, so the rock is closer to being a liquid.
Station D
Yes. Due to convection, the mantle moves much slower than the crust. The crust also moves slowly, around the speed at which fingernails grow, but faster than the mantle.
The composition of Earth's center is mostly solid. Seismic waves travel slower through the liquid, so if it travels quickly from one side of the Earth to another it infers that the center is mostly or completely solid
Seismic waves typically travel slower in liquids and faster in solids.
The composition of a meteorite has high amounts of iron, nickel, and magnesium. If the theory that Earth was made from meteorites is correct, then Earth should have lots of iron, nickel, and magnesium somewhere. Compared to a meteorite, there is only a small percentage of these elements on the crust, so this leads to the idea that the composition of the core must be iron and nickel.
The line with which a compass aligns is called a magnetic field line
Permanent
The south pole of a magnet is attracted to the Earth's magnetic north pole.
No, they aren't always the same distance apart.
This is because the magnetic north poles travel about 10 km every year and the geographic North Pole doe not moves much at all.
The angle of declination would grow greater from geographic north to magnetic north.
The angle of declination grows greater as you get closer to the geographic poles
So you make sure that you are traveling in your intended place of travel and not end up too far west or east of the place you actually want to be.

slab-pull
slab-push
slab-pull is evidence that backs the convection current model. It is that gravity pulls down the subducting crust, pulling the crust w/ it.
slab-push is another piece of evidence that is when magma pushes its way up through the crust, pushing it apart. One example of a slab-push. One example of this is the Hawaiian islands.
slab-pull is thought to be the stronger force behind plate movement.
At subduction zones, oceanic crust is pushed under the crust and melts. This creates magma which comes up as a volcano, which is why you find volcanoes near subduction zones

He used the shape of the continents, dinosaur fossils, glacier evidence, and tropical plant fossils as evidence for his theory of continental drift.
The different pieces of evidence could have been carried by land between the continents before in sank under.
He couldn't explain what caused the land masses to move.
A super-continent formed because all the plates shifted together
After the super-continent formed, mantle convection caused the plates to shift away from each other and form the continents we know today.

Three things that can come out of a volcano during an eruption are gas, tephra, and lava.
A super hot-spot supervolcano such as Yellowstone forms by magma rising through the crust for tens of millions of years
Mount Saint Helens is a composite cone volcano
Composite volcanoes are formed by built-up layers of pyroclastic flow, creating a sharp peak with symmetrical sides. Hot-spot volcanoes are just magma rising through the crust.
No, they do not erupt more explosively than other volcanoes. One example of a hot-spot volcano is the Hawaiian Islands which have formed slowly over millions of years, not a sudden explosion like some other volcanoes.
This is because the hotspot stays in one place, but the ocean crust moves over it. So the islands that form from the hot spot will form at then move away from the hot spot. A famous example of this is the Hawaiian islands.
I look at the top-level domain to determine who wrote the article. So if it ends in .org, then I know it is from an organization while .gov is government. I also check the cited sites at the bottom of the page to determine if they are gathering quality information by looking through them.

When the mineral significantly changes, practically disappears
No, they all do change over time but they definitely change differently.
When the salt was added to water, it disappeared without any bubbles. However, with vinegar and chalk, there were many bubbles. The minerals had clearly two very different reactions. Also, when water was mixed with chalk nothing changed. This is my evidence that proves that rocks are not equally chemically weathered by water.
They are definitely changing parts of Earth's surface that contain rocks made of the three types of minerals I modeled because the rainwater would be dissolving the parts of the rocks made with sodium chloride and calcium carbonate.
How does water change the mass of a mineral over time and what minerals are affected the most by water.
I would drip water with a pipette on different minerals. I would weight the before and after amount to see how they would differ. I would also make sure that all the water is evaporated before measuring the after masses.
-The amount of mineral before water is added will be the same
-the amount of water dripped would be the same
-The same amount of time will be given to each material to be dissolved
-I will be changing the mineral for each experiment
-I will observe how the mass of minerals changes after water is dropped onto it. I will measure the amount of mineral before and after to compare the results of the tests.
The mass of the salt would have been the most greatly changed - In part one, the salt had the greatest chemical reaction with water
The chalk would be second mostly changed- In part one, although a significantly amount of was not dissolved, I think the properties of chalk would cause some of it to evaporate, so the mass changed
The water dissolving rock was the weathering part of my experiment. Erosion was modeled when the water created a small hole in each material because it was being displaced. I only modeled solution chemical weathering in my experiment.
No not really. I was replicating weathering erosion in a very controlled environments which is not like the natural world. In the natural world, there are plants, animals, and other things that cause weathering along with water. To make my setup more like the real world, I think I would have to physically displace some of the material and drip water in different spots to represent wind and rain better.
