What change in Earth's atmosphere alowed life to form?
a
Solar radiation split molecules
b
A meteor strike
c
The formation of the oceans
d
The development of an ozone layer
Answer:
D
Explanation:
the ozone layer formed and began to shield the surface of the Earth from the harmful ultraviolet light. This allowed life forms to evolve to survive on the surface of the oceans and on land and also allowed organisms who metabolize oxygen (like us!) to develop.
The change in the Earth's atmosphere which allowed life to form is the development of an ozone layer. Thus, the correct option is D.
What is the Ozone layer?The ozone layer is a region of the Earth's stratosphere which absorbs most of the Sun's ultraviolet radiations. Earth's stratosphere contains a high concentration of ozone in relation to other parts of the atmosphere, although it is still present in small amount in relation to other gases in the stratosphere.
The ozone layer in the stratosphere absorbs a big portion of the radiations from the sun, preventing it from reaching the planet's surface. Most importantly, ozone absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light which comes from the sun that has several harmful effects.
Therefore, the correct option is D.

3. How does energy from Earth's core transfer through the geosphere?
Answer: Heat flow is the transfer of energy from a warmer object to a cooler object. Energy from the sun reaches Earth by radiation. Energy is transferred through the oceans, the atmosphere, and the geosphere by convection. Energy is transferred between the geosphere and the atmosphere by conduction.

Please I need help. Please and thank you
Answer:
hehe true
Explanation:
The Pacific Plate, which drives much of the tectonic activity in the Ring of Fire, is cooling off. Scientists have discovered that the youngest parts (about 2 million years old) are cooling off, contracting faster than the older parts of the plate (about 100 million years old.) The younger parts of the plate are the most active parts of the Ring of Fire.
What idea is the BEST supported by this paragraph?
(a)Movement from the contraction of the cool plates is contributing to tectonic activity in the Ring of Fire.
(b)the youngest parts of the plates will stay very cool completely and stop their tectonic activity.
(c)Most older parts of the Ring of Fire have stopped and will soon cool completely and stop their tectonic activity.
(d)The pacific plate has both the oldest and the youngest active volcanoes in the entire world.
The Ring of Fire is the result of tectonic plates, huge slabs of Earth's crust that fit together like
pieces of a puzzle. The plates are constantly moving atop a layer of solid and molten rock called
the mantle. Sometimes these plates collide, move apart or slide next to each other.
How does the analogy to a puzzle help the reader to understand tectonic plates?
(A) It helps the reader to imagine how large and heavy they are.
(B) It helps the reader to consider their exact shapes and curves.
(C) It helps the reader to visualize how their edges meet and align.
(D) It helps the reader to understand that they can be lifted.
Answer:
the answers is C) It helps the reader to visualize how their edges meet and align
Plate movement results in three types of tectonic boundaries: convergent boundaries, where plates move into one another.
It helps the reader to visualize how their edges meet and align.
How can you describe the movement of plates?Plate movement results in three types of tectonic boundaries: convergent boundaries, where plates move into one another, divergent boundaries, where plates move apart, and transform boundaries, where plates move sideways in relation to one another. They move at a one to two inch (three to five centimeter) per year rate.The numerous tectonic plates constantly shift and interact. This motion changes the shape of the Earth's outer layer. This process produces earthquakes, volcanoes, and mountains.According to plate tectonics theory, pieces of the Earth's lithosphere are in slow, constant motion as a result of mantle convection currents.To learn more about : plate tectonics theory

Answer:
A layer of sedimentary rock lies next to a layer of igneous rock. If inclusions from the igneous layer are scattered in the sedimentary layer, then the layer of sedimentary rock is richer in minerals than the igneous layer.
Explanation:
The igneous rocks are a good source of minerals like pyroxene, mica, amphibole, olivine, etc. Some common minerals like quartz, feldspar, and muscovite are found in both igneous and sedimentary rocks. But the major clay minerals like calcite, gypsum, dolomite, and halite are only found in the sedimentary rocks. Thus, scattering inclusions from the igneous layers over the sedimentary layer would make the sedimentary layer richer in mineral_________________________________________________________

Which of the following is an example of ecological succession?
A
New trees are now providing constant shade, and plants around them that needed sun to survive are being overgrown by shade-dependent shrubbery.
B
Marigolds and sunflowers are planted every year in a flower bed. Both flourish for a few months and then die off at the end of the season.
C
Every spring buds appear on the trees, then they turn into leaves. In the fall, these leaves change colors and die and eventually fall off the trees.
D
Tomato plants growing in a pot are replanted into the ground next to basil and other herbs. All of the plants flourish.
Ecological succession is demonstrated by the fact that nearby plants that need sunlight to flourish are now being supplanted by vegetation that requires shade. So, the correct option is A.
What is an Ecological succession?Ecological succession is the process of change in an ecological community's species composition over time. The time frame can be many decades or less or more. The cycling of nutrients like carbon, nitrogen, and sulphur is made possible by bacteria.
Ecological succession is the progressive change that occurs in a species through time as a result of the environment. Given that all biotic elements must adapt to changes in our environment, this change is both predictable and unavoidable.
The completion of this process will bring the ecosystem to equilibrium. A climax community is the one that succeeds in achieving this goal. Some species multiply in an effort to reach this balance, while others decline.
Therefore, the correct option is A.

Write a hypothesis about the effects of magnetic and electric fields. Use the format of "if . . . then . . . because . . ." and be sure to answer the lesson question: "How can magnetic and electric fields be demonstrated?" Please halp me without the sample response!!!!
Well, I was taught about hypotheses differently but I'll try.
Answer: "If magnetic fields can repel and attract electric charges, then electric fields can exert a force on a positive charge because the electric field is radially outward from a positive charge and radially in toward a negative point charge."
I hope I don't mess up your grade and if I do then I'm extremely sorry.
Electric and magnetic fields can be demonstrated using electromagnets such as transformers.
What are electric fand magnetic fields?Electric fields are regions where electric force van be felt.
Magnetic fields are regions where magnetic force can be field.
If electric fields are force fields, then they can be felt from a distance by charges because force fields are felt from a distance.
If magnetic fields are directional, then north poles will repel north poles because like poles repel each other.
Therefore, electric and magnetic fields can be demonstrated using electromagnets such as transformers.
