Explanation:
Often, the rock layers bookending the mass extinction are noticeably different in their compositions. These changes in the rocks show the effects of environmental disturbances that triggered the mass extinction and sometimes hint at the catastrophic cause of the extinction.

Answer:
This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four.

How do the light rays emitted by a candle travel?
Answer:
Explanation:
The light rays coming from the unlit candle and the reflected light rays of the lit candle are superposed on top of one another. ... For very transparent substances like glass, only about 5 percent of the light that hits it is reflected. The remaining 95 percent is transmitted—it passes right on through.

Which graph above shows an object’s acceleration? Why did you choose that graph(explain why)
Velocity vs. Time shows an objects acceleration because... in Position vs. Time the line does not go through the origin and it’s very uneven, But Velocitu vs. time goes through the origin and has straight lines.
Answer:
B.
Explanation:
Because the lines are vertical no so wormy like.
a
a decrease in the number of zebra mussels along the waterways

What is unique about obtaining water from an artesian well?
The water is heated by magma or hot rocks.
The water is found in an impermeable layer.
The water is under pressure naturally and no pump is needed.
A mechanical pump must be installed to bring water to the surface.
Answer:
The water is under pressure naturally and no pump is needed.
Explanation:
C
The water in artesian wells is under natural pressure and requires no pump.
What are artesian wells?They are wells that contain water that is under natural flowing pressure. Thus, there is no need of using artificial pumps in order to get the water to the surface.
Artesian wells are dug on lands with special geological features that enable the water to flow out under natural pressure.
Artesian wells differ from other types of wells that require mechanical or electric pumps before the water can get to the surface.

(a) evaporation increases
(c) freezing increases
(d) melting increases
(e) precipitation increases
Where does the energy that causes evaporation come from?
What role does gravity play in the water cycle?
Describe the flow of one molecule of water through the water cycle, beginning in the ocean.
Answer:
A and E.
Explanation:
When water evaporates, it leaves the salt. When rain falls, the salt is diluted. The sun causes the evaporation. The also the sunlight is the energy source, the greatest force propelling the water cycle is gravity. Gravity is the force of attraction between two objects, and Earth’s gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Also Water travels in a continuous path through Earth called the water cycle. The journey starts in the Earth's oceans. As the Sun heats the ocean, the water evaporates into a gas. The gas meets cooler air, and the gas changes into droplets of tiny water molecules. This process is called condensation. Little droplets of water fall back down to Earth again as precipitation. The precipitation fills up the rivers and various other things and the cycle begins all over again. Now with this being said, there is much more than just this!
Good luck!

Why is it necessary to see a similar pattern of change in fossils from several places in order to conclude that an extinction happened?
One can learn a lot about the history of life on Earth thanks to fossils. They can help us understand the origins of life and humanity, the evolution of the planet and its environment across time, and the once-connected nature of the continents that are now widely separated.
What are fossils ?Any surviving remnants, impression, or evidence of a once-living creature from a previous geological epoch is referred to as a fossil. Examples include fossilized bones, shells, exoskeletons, animal or microbe impressions in stone, amber-preserved artifacts, hair, petrified wood, oil, coal, and DNA traces.
Scientists use the fossil record to seek for patterns that may be used to infer which creatures are related to one another, how groups of organisms evolved through time, and how the Earth's climate affected the kinds of plants and animals that could survive for a very long time.
Thus, a lot about the history of life on Earth thanks to fossils. They can help us understand the origins of life and humanity.

CH4 + __O2 → CO2 + ___H2O
balance this equation
Explanation:
need points bye have good day
Answer:
CH4+2O2→CO2+2H2O
Explanation:
Start with the least common atoms and leave things like H and O to the end.
You need to have the same number of methane reactants as carbon dioxide products because there is one carbon in each. I’ll set them both to 1 for now. O see two things with oxygen on the product side so we will have to juggle numbers a bit to figure out those. There is only H in the water so we’ll go there next. One CH4 gives 2 water molecules so we have that done now. At last we can tackle the O atoms. In two waters there are 2 and in the CO2 there are two more so a total of 4 O atoms in the products so we need two O2 molecules in the reactant side.

If two people attempt the same maneuver, what determines the amount of force that each is required to exert?
Answer:
Explanation:
you need to change either the turn of the jump or push off higher or lower from the wall
If the two individuals start at the same position and time, the amount of force exerted by each person is determined by mass of the person.
The amount of force exerted by each person is given by Newton's second law of motion, which states that the force exerted by an object is directly the proportional to the product of mass and acceleration of the object.
F = ma
where;
F is the applied forcem is the mass of the objecta is the acceleration of the objectThus, If the two individuals start at the same position and time, the amount of force exerted by each person is determined by mass of the person.

What happens to the motion of an object if forces acting on the object are equal and balanced?
A. The object begins to move
B. The object begins to slow down
C. The motion of the object does not change
Answer:
When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object they are acting on remains unchanged. The object may change its speed (speed up or slow down), or it may change its direction.
So I think its C
You see this is because if the forces were different the object would either speed up or slow down but in this case the forces are equal so the motion of the object does not change.

The melanin provides protection against skin cancer by absorbing harmful UV light from the electromagnetic spectrum.
What is electromagnetic spectrum?
The electromagnetic spectrum consists of radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

What patterns in the rock layer fossils helped you identify an extinction?
Earth’s surface is constantly changed by erosion and deposition. Erosion breaks down Earth’s surface by carrying materials away from an area. Deposition builds up Earth’s surface when these materials are deposited in an area over time.
Which landform results when erosion occurs during volcanic eruptions, but deposition does not directly contribute to creating the landform?
volcanic soil
cinder cone
caldera
lava plateau
Answer:
Caldera
Explanation:
C
The landform results when erosion occurs during volcanic eruptions, but deposition does not directly contribute to creating the landform is caldera.
Where does the operation take place?Involving the wear, transport and deposition of soils and rock particles. Erosion is the process of wear, transport and sedimentation of soil, subsoils and rocks as an effect of the action of erosive agents, such as water, wind and living beings.
In this case the caldera is landform results when erosion occurs during volcanic eruptions, but deposition does not directly contribute to creating the landform.
