Answer:
you can classify a mineral by its appearance and other properties. The presence of a mineral is defined by the color and luster, and the color of the powdered mineral is described by the band. Every mineral has a distinctive density. To compare the hardness of rocks, the Mohs Hardness Scale is used.
Explanation:
Answer:
Luster, hardness , colour , clevage and magnetism
Explanation:
1. Luster makes sure the light is reflected by the mineral.
2. On the 10-point Mohs scale, which is basically a scratch test, hardness is measured. Take an unidentified mineral and scrape it like a fingernail with an object of known hardness.
3. Zurite, for instance, is often a deep blue, and malachite is gray.
4. In minerals that appear to divide along one or more flat surfaces or planes, cleavage may be observed.
5. Magnetite, for instance, has a heavy pull that even weak magnets can draw. But there is only a poor attraction to other minerals, particularly chromite (a black oxide) and pyrrhotite (a bronze sulfide.)
Jenna notices that the speed of the wind has increased throughout the day. What is causing the faster wind?
There has been no precipitation.
The difference in air pressure has decreased.
The difference in air pressure has increased.
The direction of the wind has changed to the south.
The speed of the wind has increased throughout the day as there has been no precipitation.
What is precipitation?Precipitation is a process in which vapor of liquid changes into small droplets.
In the day time temperature of the atmosphere is high as compare to the night, so rate of precipitation is low at the day time due to which speed of the wind has increased as compare to the night time.
Hence, option (a) is correct i.e. there is no precipitation.

Answer: C
Explanation:
4P + 5O2 → P4O10 How many phosphorus (P) atoms are on each side of the equation? How many oxygen atoms are on each side?
Answer:
4 p and 10 O on both sides
Explanation:
on the reactant side you can see easily that there are 4 P. With the oxygen on the reactant side you take the coefficient (5) times the subscript (2) which gives a total of 10 Oxygens.
On the product side there is a subscript of 4 next to the p, and a subscript of 10 next to the O
They are equal on both sides so you are done.

Which best describes the role of the water cycle? HELPPPP ASPPPPP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Circulates existing water on Earth.
The water cycle, also known as the hydrological cycle, refers to the continuous movement of water on, above, and below the Earth's surface. It involves processes such as evaporation,
condensation, precipitation, and runoff. The water cycle is responsible for circulating existing water on Earth, redistributing it from one place to another, and maintaining a constant supply of water in different forms (liquid, vapor, and ice) across various reservoirs like oceans, lakes, rivers, and the atmosphere. It plays a crucial role in balancing the Earth's water resources and supporting life on our planet.
Therefore the role of water cycle is best described by

A student tests the pitch of different-sized rubber bands by stretching them around a box and then plucking them. What pitch does a thick rubber band have, and why?
A thick rubber band vibrates fast, so it produces a low pitch sound.
A thick rubber band vibrates fast, so it produces a high pitch sound
A thick rubber band vibrates slowly, so it produces a low pitch sound.
A thick rubber band vibrates slowly, so it produces a high pitch sound.

Explanation:
You want to push a table 5 feet across the floor. How would a decrease in the resistance caused by friction change the amount of force needed to move an object?
Write in only 1-2 sentences.
help please!
Answer: A decrease in friction will allow you to move the table with less force as friction would waste some the energy provided.
Answer: By reducing the friction, either by using lubricants, reducing the roughness of the surfaces, or other means, the resistance to motion is decreased.
Explanation:
A decrease in the resistance caused by friction would make it easier to move an object, which means less force would be needed to push the table across the floor. Friction is a force that opposes the motion between two surfaces in contact, and it can make it harder to move objects. By reducing the friction, either by using lubricants, reducing the roughness of the surfaces, or other means, the resistance to motion is decreased.
According to Newton's laws of motion, the force required to move an object is directly proportional to the resistance caused by friction. Therefore, when the resistance decreases, the force needed to move the object decreases as well. With less friction, it would be easier to overcome the resistance and push the table across the floor, requiring less force to achieve the desired movement.

Why do tides have a regular cycle of 12 hours even though the Moon completes one revolution of the Earth every 29.5 days?
(HELP PLEASE!!)
A. The Earth is rotating and completes a rotation every 24 hours. As it rotates, its distance from the Moon changes every 12 hours. This causes the cycle of high and low tide.
B. The Earth is rotating and completes a rotation every 24 hours. The moon also rotates as it resolves around Earth, which causes the cycle of high and low tide.
C. The Earth is rotating and completes a rotation every 24 hours. This means that the side of the Earth far from the Moon will be near the Moon 12 hours later, restarting the cycle of high and low tide.
D. The Earth is rotating and completes a rotation every 24 hours. This causes day and night to occur. High tide only occurs during the evening, and low tide only occurs during the day.
Answer:
D
Explanation:
The Earth is rotating and completes a rotation every 24 hours. This causes day and night to occur. High tide only occurs during the evening, and low tide only occurs during the day.

Use the following scenario to answer the question.
Pete hangs a weight from a spring and then releases it. He watches as the spring oscillates back and forth. Pete says that this will repeat forever.
Which of the following states if Pete is right or wrong and explains the reasoning correctly?
( help please! )
A. Pete is correct because simple harmonic motion is occurring, and this type of motion should continue on forever.
B. Pete is not correct because friction will cause the spring to fall and rise with a shorter distance during each oscillation. The spring will eventually come to rest entirely.
C. Pete is not correct because eventually the weight will fall off the spring, causing the motion to cease.
D. Pete is correct because friction will cause the spring to fall and rise with a greater distance during each oscillation. It will never stop completely.
Answer:
Option: B
Explanation:
The correct answer is B. Pete is not correct because friction will cause the spring to fall and rise with a shorter distance during each oscillation. The spring will eventually come to rest entirely.
The motion of the spring is affected by friction, which gradually dissipates its energy. As a result, the amplitude of the oscillations decreases over time until the spring eventually comes to a stop. This phenomenon is known as damping, and it causes the motion to cease rather than continue indefinitely.[tex][/tex]

Which water crisis is the most critical to resolve?
Option (A) Circulates existing water on Earth
The most critical water crisis to resolve is water scarcity, which affects approximately 2.2 billion people worldwide.
Explanation:
Water crises are a pressing global issue, and identifying the most critical one to resolve requires considering various factors. While all water crises are significant, water scarcity stands out as one of the most critical challenges to address.
Water scarcity occurs when the demand for water exceeds the available supply, leading to water stress and shortages. Approximately 2.2 billion people worldwide lack access to safe drinking water, and this number is expected to increase due to population growth, climate change, and inefficient water management.
Resolving water scarcity requires a multi-faceted approach. It involves implementing sustainable water management practices, such as water conservation, rainwater harvesting, and efficient irrigation techniques. Additionally, investing in infrastructure development, such as building reservoirs and improving water distribution systems, can help alleviate water scarcity.
By addressing water scarcity, we can improve access to safe and clean water, enhance food security, and promote sustainable development. It is crucial for governments, organizations, and individuals to prioritize resolving water scarcity to ensure a better future for all.
