Answer:
The Earth’s lithosphere, which includes the crust and upper mantle, is made up of a series of pieces, or tectonic plates, that move slowly over time.
The law of conservation of matter states that matter can be neither created nor destroyed. Your friend shows you the following chemical equation: The equation was CaCO3 →CaO+CO2
He says that because the oxygen atoms are split between two different molecules in the products, the equation does not support the law of conservation of matter. Is your friend right? Explain your answer. Draw a model showing the number of each type of atom in the reactants and products. Use your model to explain your answer.
PLEASE HELP
Yes, our friend is right, because there is no contradiction to the law of conservation of mass in the above equation. It just the mass of the product is equal to the mass of reactants.. and that is shown in the equation you have presented earlier
Answer:correct
Explanation:
Here’s the last two questions again, tysm!
Answer:2 possible ways for question 16 and for question 17 they could be two posible causes
Explanation for 16:
1)you can use velocity like a rocket fast enough to reach the meteor and crush it mid way to earth 2)you can use mass like a big rock but if the meteor is to big then use velocity too for it can help the mass have a big colisio whit the asteroid whit a catapult or a big launcher and the moon gravity can help to because of the force
Explanation for 17:the two were in a different road and the one that is sideways was at a bigger speed then the car left in the middle and because of the mass the collision was worse For the one in the middle

Answer:
this is somthing you have to do on your own for now
Explanation: i cant answer it
Describe the relationship between wavelength and the energy of the wave.
Please complete this in 3-5 sentences.
Answer:
Magnetic forces are stronger closer to magnets. The Wednesday launch stored more potential energy, and launched the spacecraft at a faster speed because the stronger magnetic field closer to the magnet resulted in a greater increase in potential energy.

As crust forms at the mid-ocean ridge, it gets pushed away from the ridge as newer crust forms. What is true about crust that forms at the mid-ocean ridge?
A: crust further away from the mid-ocean ridge is younger and crust closer is older
B: crust further away from the mid-ocean ridge is older and crust closer is newer
C: crust is not created at the mid-ocean ridge
D: crust further away from the mid-ocean ridge and crust closer are the same age
