Answer:
☞rock cycle
=> The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions.
=> There are three main kinds of rocks: igneous rock, metamorphic rock, and sedimentary rock. ... It can erode into sediment or melt into magma. It is formed under extreme pressure and temperature deep inside mountain chains.
Explanation:
You will observe the orbits and you have to determine how many planets are in the habitable zone and how many are orbiting successfully. Based on the mass of the star and the placements of the planets, planets may swerve into the star and vanish, collide with each other and vanish, float out of orbit, or all orbit successfully. You will record this information and each planet's orbit in your data table for each trial. If the mass of the sun is 1x, planets will fall into the habitable zone if I place a planet in orbits (Orbit=1,2,3,4,5,6,7,8), and all planets will orbit the sun successfully.
If the mass of the sun is 2x, planets will fall into the habitable zone if I place a planet in orbits (Orbit=1,2,3,4,5,6,7,8), and all planets will orbit the sun successfully.
If the mass of the sun is 3x, planets will fall into the habitable zone if I place a planet in orbits (Orbit=1,2,3,4,5,6,7,8), and all planets will orbit the sun successfully.
Answer:t of orbit, or all orbit successfully. You will record this information and each planet's orbit in your data table for each trial.

A sample of a pure substance with a density of 3 g/mL is separated into two pieces. One piece has a mass of 50 g and the other piece has a mass of 25 g.
What is the volume of the smaller one?
Answer:
8.3ml
Explanation:
to get volume u have to divide 25g over the density, i rounded to the nearest tenth, if you don't want to then write out the full number with all the decimals
An object’s mass is determined to be 32.5 g. When the object is placed in a graduated cylinder containing 175 mL of water, the water in the cylinder rises to a level of 187.5 mL. What is the density of the material?
When the object is placed in a graduated cylinder containing 175 ml of water, the water in the cylinder rises to a level of 187.5 ml , this implies that volume of content in the container has increased , the increased volume is volume of the object placed
So, Volume of object
= Increased Volume - Initial volume
= > 187.5 -175
= > 12.5 ml
Since 1 ml = 1 cm³ we can write
[tex]\quad[/tex]12.5 ml = 12.5 cm³
Now,
[tex]\green{ \underline { \boxed{ \sf{Density= \frac{Mass}{Volume}}}}}[/tex]
Putting Values -
[tex]\begin{gathered}\\\implies\quad \sf Density = \frac{32.5}{12.5} \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf Density = \frac{325}{125} \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf Density = 2.6 g/cm^3 \\\end{gathered} [/tex]
>> The density of the material is 2.6 g/cm³
You have a sample with a volume of 55.7 mL and a mass of 67.9 g. Will this sample float in water? Why or why not?
Answer:
No it will not
Explanation:
It will not float because the density is 1.21903052065, it needs to be less than 1 to float

B. Crowding and food quality
C. Energy consumption and refrigerants
Answer:
Answer down below
Explanation:
if it has to be 2 of these I think it would be A and B but if it is only one Answer it would be B
Crowding and food quality are two environmental issues of restaurants.
What is the meaning of environmental issues?Environmental issues are defined as harmful effects to Earth and its natural systems due to the actions of humans.
The food supply chain and restaurant customer experience generate a lot of waste – from food waste to plastic waste, and more. Unfortunately, one-third of the world's food gets wasted. This waste alone amounts to 8% of the world's greenhouse gas emissions.

Only answer if you know 100% it's correct. this means if you're not sure, DON'T answer.
Answer:
D is the answer
Explanation:
First of all, conservation is when you conserve resources, or use them less, to be better for the environment. Using a gas powered car does not, as carbon monoxide and other toxic gases are sent into the atmosphere. Using a disposable bag is bad because the plastic is sent away to the environment every time you shop. Leaving water running when you brush your teeth wastes water and is bad for the environment. Recycling aluminium cans and glass bottles is good for the environment, and is conserving resources because the cans and bottles are reused, so instead of wasting, you are reusing.

The terrarium model shows the many different aspects of life. The dirt shows the geosphere, which is the ground thaat the plant can grow in. The biosphere is represented by the plant growing, and the hydrosphere is the water that you use to water the plant, and the condensation that will gather on the lid. The atmosphere is the air inside the jar.
Explanation:
Each of the above show how the environment works.
What is the chemical test for water
Copper(II) sulfate in its purest form is white. Because it is devoid of water, it is also known as anhydrous copper(II) sulfate. A sample of copper(II) sulfate becomes blue when water is present.
• Temperature measurements
Temperature testing aids in determining the pace of biochemical reactions in an aquatic environment, as well as whether they can occur at all. If the water temperature is too high, the water's ability to contain oxygen is reduced, and organisms' ability to withstand certain contaminants is reduced.
• Checking the pH level
This instrument determines the acidity of water. The majority of aquatic species can only thrive in a pH range of 6 to 8.
• Test for chloride
Chloride may be found in both fresh and salt water. Mineral dissolution and industrial pollutants, on the other hand, can worsen its levels.
• Testing for salinity
The total amount of non-carbonate salts dissolved in water is calculated. The salinity of your groundwater can tell you how salty your topsoil will become as the water table rises.
• Oxygen Dissolved Test
The amount of oxygen dissolved in water is measured with this device. Aquatic life can't conduct cellular respiration without it, hence it's an important indication of water quality.
• Test for turbidity
Measures the quantity of suspended particle matter in the water, or, to put it another way, how clear the water is. When there is a lot of turbidity in the water, photosynthesis suffers because light can't get through, which raises the water temperature.

10. Write your conclusion.
Answer:
- Independent Variable: Sand, water (variable that changes)
- Dependent Variable: Heat (Sun)
- Control Variables: Environment, container, therometer
Hypothesis: If the sand and water both receive solar radiation, the sand will heat up faster.
Materials:
- 2 thermometers
- 2 plastic boxes (These should be identical)
- Sand
- Water
Procedure:
- Pour sand into one of your plastic boxes to a depth of two inches. Pour water into the other plastic box to a depth of two inches. The sand box will represent land while the water box represents a body of water.
- Place the two boxes in a location that receives direct sunlight and place one therometer in the sand, and the other in the water.
- For a period of 30 minutes, check the temperature of both boxes every 10 minutes. Record the temperatures in a chart/graph
Observations: The temperature of the land (sand) was higher than the water.
Results: Land absorbs much more solar radiation than water, due to the fact that most land surfaces are darker than water, thus attracting heat. Water typically reflects solar radiation that reaches its surface back to the atmosphere. As a result of land absorbing more solar radiation, the land also retains more heat. This validates my hypothesis of the land (sand) heating faster.
