Answer:
Geosphere and Hydrosphere
Explanation:
Rain is water, and the volcanic eruption from the valcano is rock
Answer:
The last one, the 4th one, D, Geosphere and Hydrosphere!
Explanation:
It is not Biosphere and geosphere or Geosphere and cryosphere because it doesn't include hydrosphere. It either has to be biosphere or geosphere with hydrosphere but it is not the biosphere with hydrosphere because the biosphere is covered with molten lava/lava rock(geosphere), so it has to be the last one, Geosphere and Hydrosphere!

What information does a phase diagram give? A. The effect of temperature on volume changes of substances B. The effect of temperature and pressure on the phase of a substance C. The effect of concentration on the freezing point of a solution D. The effect of oxidation number on the melting point of a metal
Answer:
B.
Explanation:
To solve this we must be knowing each and every concept related to phase diagram. Therefore, the correct option is option B among all the given options.
What is phase diagram?A phase diagram is a graphic that depicts a substance's thermodynamic state at various pressures and temperatures. The areas surrounding the lines represent the phase of both the material, and the lines represent the points at which the phases are all in equilibrium.
A phase diagram often contains lines of equilibrium and phase boundaries. Multiple phases like matter can exist in equilibrium along these lines. The lines also illustrate the locations of phase transitions. Phase diagram tells about the effect of temperature and pressure on the phase of a substance.
Therefore, the correct option is option B among all the given options.

Which of the following is an accurate description of an ionic bond? Anions and anions attract. Cations and cations attract. Cations and anions attract. Atoms share electrons.
Answer:
Atoms of different elements, having gained or lost electrons, form negative and positive ions that are bonded together by attractive forces between ions with opposite charges.
Explanation:
The atoms have different numbers of neutrons and the same number of protons. hope this helps you :)
Which of the following would have the best thermal conductor properties?
A. A thick mug
B. A plastic cup
Ос. A paper cup
D. A cup made of metal
Answer:
D
Explanation:
metal is a major cunductor of heat
A cup made of metal would have the best thermal conductor properties.
The answer is option D.
Is a metal cup a good conductor of heat?Metals have unfastened electrons that are not bounded to the atoms. those electrons are unfastened to move around within the metal, colliding with the metal atoms and shifting heat to them successfully. This makes metals higher conductors of warmth than maximum other materials.
Which of the following would have a high-quality thermal conductor?Diamond is the leading thermally conductive material and has conductivity values measured 5x better than copper, the maximum synthetic metallic inside the united states of America. Diamond atoms are composed of a simple carbon spine this is a really perfect molecular structure for an effective heat switch.

which of the following accurately describes the transmission of sound and waves in seawater? A sound travels faster in seawater because seawater is less compressible than the atmosphere. B sound travels slower in seawater because seawater is less dense than the atmosphere C sound travels slower in seawater because seawater is colder than the atmosphere D sound travels faster in seawater because seawater is less dense than the atmosphere.
Answer:
Salty water is more dens than freshwater. answer is D
Explanation:
The statement which accurately describes the transmission of sound and waves in seawater that sound travels faster in seawater because seawater is more dense than the atmosphere.
What is sound waves?Sound wave is an example of longitudinal wave. It always travel through any medium as it requires some objects to transfer its energy.
Travelling of sound waves is directly depends on the vibration of the particles of the medium and in seawater particles of the water in the form of salt are present in much amount which makes it dense. And due to dense medium sound waves will travel through seawater through the fast speed.
Hence, sound travels faster in seawater because seawater is more dense than the atmosphere.

which diagram(s) represents the bonding pattern of metals? a)A and B
b)C and D
c)A
d)C
the other guy is totally wrong. the answer is a for sure. C is showing a covalent bond between 3 atoms. Metals bond differently. Like shown in a and b. However b is innacurate because it shows the electrons being the largest(since they are negatively charged and there is a - sybmol), and we all know protons are much larger than electrons. SO a is correct because it depicts the positive protons(+ symbol) as the biggest. So go with a.

Who is correct? Reggie, because baking and melting cause bonds to be broken, leading to a chemical change. Reggie, because objects that are heated always undergo chemical changes. Charlotte, because melting objects only sometimes cause a chemical change. Charlotte, because baking causes a chemical change, but melting objects is a non-chemical change.
Answer: Charlotte, because baking causes a chemical change, but melting objects is a non-chemical change.
Explanation: Baking is a chemical change you cant turn it back to what it was before. Its chemical properties have changed. Melting is a physical change. Its chemical properties are still the same it has not changed. It just changed it's physical form but the object is still the object.
Answer:
Charlotte, because baking causes a chemical change, but melting objects is a non-chemical change.

Which describes a climate effect on the rate of weathering? Cold climates favor mechanical weathering. Chemical reactions occur slower at higher temperatures. Lower precipitation levels lead to more chemical reactions. The chemical reaction rates of minerals are not impacted by temperature.
Answer:
the answer is Cold climates favor mechanical weathering.
Explanation:
I got 100% on the Quiz
Statement that describes climate effect on the rate of weathering as regards this question is A:Cold climates favor mechanical weathering.
Weathering can be regarded as disaggregation of rocks into smaller bits by the actions of agents of weathering such as man, animals, water and so on.However, climate can also have effect on the rate of weathering, when there is cold climate, mechanical weathering is favoured.Option B,C,D are wrong because high temperature brings about increase in rate of chemical weathering.
Therefore, option A is correct.
