If he moves a lot then it will tip over
Mike created the following table for the layers of the Earth. What needs to be corrected?
The mantle is made of metal and the outer core is made of rock.
The outer core is liquid and the inner core is solid.
The crust is 2,900 km and the mantle averages 45 km.
The crust is semi-solid and the mantle is solid.
Answer:
The last option.
Explanation:
The crust is solid and the mantle is semi-solid, it's the wrong way around.

Taylor created the following table to compare the three types of rocks. What correction needs to be made to the information in the table?
Examples of igneous rock are sandstone and limestone and examples of sedimentary rock are granite and basalt.
Examples of igneous rock are granite and marble and examples of metamorphic rock and basalt and gneiss.
Metamorphic rocks are made from the cooling and hardening of sediment and igneous rock is made from high heat and pressure causing chemical change.
Igneous rocks are the cooling and hardening of magma or lava and sedimentary rock is made of sediment cemented together.
Igneous rocks are the cooling and hardening of magma or lava and sedimentary rock is made of sediment cemented together.
Igneous rocks are formed by cooling and hardening of sediment. The examples of igneous rocks include granite and basalt. Metamorphic rocks are formed by the treatment of high heat and pressure. The examples of metamorphic rocks are marble and gneiss.
What are Igneous rocks?Igneous rock or magmatic rock, is one of the three main rock types, and the other rocks being sedimentary and metamorphic rocks. Igneous rock is formed through the cooling and solidification of the magma or lava in the volcano. The magma can be derived from partial melts of existing rocks in either a planet's mantle or the crust.
Metamorphic rock are formed from other type of rocks, however they have been substantially changed from their original igneous, sedimentary, or earlier metamorphic forms. Metamorphic rocks form when the rocks are subjected to high temperature, high pressure, hot mineral-rich fluids or, more commonly, some of the combination of these factors.

Study the image of the moving car.
A car that is driving at the flat bottom of the hill would have ______ potential energy and _______ kinetic energy.
- High
- Low
- Equal
Answer:
Low Potential energy and High Kinetic energy
Explanation:
Hope this helps and have a good day! Apologies if it's wrong.<3
Answer:
Low, high
Explanation:
The potential energy for the car would be low as it is on the flat bottom of the hill. Since it is still driving, it does have some kinetic energy. I'm assuming that it is currently moving at a constant velocity, so the kinetic energy would remain high (remember, the kinetic energy of an object is the energy that it possesses due to its motion).

if you dig a hole through the earth, from one hemisphere to the other, and drop a tennis ball into it, would it get stuck at the center, since thats where gravity's at, or would it pop up out the other side??
Answer:
Depending on which hemisphere it is, like western to eastern, It would most likely get stuck at the center. You would also have to put more things into thought like acceleration, velocity, and speed.
BUT since the question asked "would it pop out the other side?", I'm assuming it's talking about northern to southern hemisphere. so in that case it would pop out the other side since gravity makes things go downwards.
Answer:
We drop a tennis ball into the hole. The stone is pulled down towards the center of the earth. It falls all the way to the middle of the earth once it reaches the middle, theres no more pull of gravity. ... It would go up a ways, then (due to the pull of gravity) fall back in the other direction, back towards the center

When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can happen only when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon.

A group of students is tasked with developing a checklist for determining whether a material undergoes a chemical or physical change. The students make a preliminary list of properties that they can test and classify each as either a chemical or physical property.
Chemical Property Physical Property
bubbles when treated with acid color
burns when placed in a candle flame odor
density hardness
boiling point mass
dissolves in water melting point
Several other students in the class claim that the checklist is incorrect.
What change should the group make to the checklist to correct their mistake?
Boiling point and density should be moved to the physical property side of the list, and color and odor should be moved to the chemical property side of the list.
