Assignment Summary For this assignment, you will construct a scientific model of the water cycle to show how water is recycled through an ecosystem. Once you have drawn your model on a poster board, you will write one to two paragraphs explaining how water is transferred within and between organisms and the environment. Background Information Water is a very important compound. Organisms need water to carry out life-maintaining processes such as growth and development. Without water, living things will not survive. Water continually flows among the atmosphere, land, water, and living organisms. This process, called the water cycle, allows water to be recycled as it moves through Earth’s spheres. Materials Assignment Instructions Step 1: For this project, you are expected to submit the following: 1. Your model of the water cycle 2. One to two typewritten paragraphs describing the water cycle Step 2: Prepare for the project. a) Read through the guide before you begin so you know the expectations of this project. Pay particular attention to the instructions you need to follow to create a model on your poster board. b) If anything is not clear to you, be sure to ask your teacher. Step 3: Gather materials for the model. a) Start with a blank poster board. Be sure to put your name on it. b) You may either draw the parts of the water cycle or print images to construct a model on your poster board. Gather any drawing tools that you will need, or print any images you want to use. Step 4: Create a model of the water cycle. a) Your model should include bodies of water such as lakes and oceans, organisms, air, and land. b) Draw arrows indicating how water moves within an ecosystem and between organisms and their environment. Be sure to include the Sun and gravity in your model. c) Include short phrases on your poster that summarize what occurs at each stage of the water cycle Step 5: Write a paragraph describing the water cycle. a) Type one to two paragraphs describing the full water cycle. Be sure to use full sentences and proper grammar.
Answer:
Explanation:
Earth's water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Water is always changing states between liquid, vapor, and ice, with these processes happening in the blink of an eye and over millions of years.

A whale is swimming in the ocean. It communicates with another whale by sending out a sound. Which of the following best
describes how the sound gets to the other whale?
A.
All of the sound absorbed by water changes to heat before getting to the other whale.
В.
The sound is transmitted through water until it reaches the other whale.
C.
All of the sound is diffused in
the water until only a faint sound reaches the other whale.
.D
The sound is reflected in the water before it gets to the other whale.
Answer:
A.
The sound is transmitted through water until it reaches the other whale.
Explanation:
When one whale makes a sound, the sound is transmitted through water until it reaches the other whale. The sound causes a ripple-like effect in the water, producing waves that travel in the water. The waves are heard in all directions. This is why humans can hear the sounds animals make underwater.
The statement which best describes how the sound gets to the other whale is that all of the sounds absorbed by water change to heat before getting to the other whale. Thus, the correct option for this question is A.
How sound may transmit from one place to another?The transmission of sounds is generally carried out through a medium in the form of waves. These sound waves involve the pattern of disturbance caused by the movement of energy.
In an aquatic environment, when one whale successfully constructs a sound, the sound is effectively transmitted through the medium that is known as water.
It remains in the form of waves until it reaches the other whale. The sound in a waveform provokes a ripple-like effect in the water and travels in the water. The waves are effectively heard in all directions.
Therefore, the correct option for this question is A.

Explain how cross cutting principles (intrusions, inclusions, faults) help to determine the relative age of a rock layer.
Answer:
The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts through. ... So the fault must be the youngest formation that is seen. The intrusion (D) cuts through the three sedimentary rock layers, so it must be younger than those layers
Explanation:
Una muestra de 2,36 gramos de NaHCO3 se descompuso completamente en un experimento. 2NaHCO3 → Na2CO3 + H2CO3 En este experimento, el dióxido de carbono y los vapores de agua se combinan para formar H2CO3. Después de la descomposición, el Na2CO3 tenía una masa de 1,57 gramos. Determine la masa del H2CO3 producido. Calcule el porcentaje de rendimiento de H2CO3 para la reacción.
Answer:
105%
Explanation:
El porcentaje de rendimiento se define como la masa obtenida del producto (En este caso, en términos de H2CO3), dividida en la masa teórica que debe ser producida.
La masa real se obtiene con las moles del otro producto que fueron producidas (Que son las mismas moles producidas de H2CO3)
Y la masa teórica se obtiene a partir de las moles de reactivo adicionadas:
Masa teórica:
2.36g NaHCO3 * (1mol / 84g) = 0.0281 moles de NaHCO3
0.0281 moles de NaHCO3 * (1mol H2CO3 / 2 moles NaHCO3) =
0.014 moles de H2CO3 son producidas. La masa es:
0.014 moles de H2CO3 * (62g / mol) = 0.871g es la masa teórica
Masa real:
1.57g Na2CO3 * (1mol / 106g) = 0.014 moles de Na2CO3
0.0148 moles de Na2CO3 * (1mol H2CO3 / 1 moles Na2CO3) =
0.0148 moles de H2CO3 son producidas. La masa es:
0.0148 moles de H2CO3 * (62g / mol) = 0.918g es la masa real producida
Así, el porcentaje de rendimiento es:
0.918g / 0.871g * 100 =
105%

Which energy transformation produces electricity and is least likely to negatively impact the environment?
A) Generating electricity from a natural gas-fired power plant
B) Generating electricity from a coal-fired power plant
C) Generating electricity from a nuclear power plant
D) Generating electricity from a solar panel system
Hello!
The answer to this question is: D) Generating electricity from a solar panel system.Thank you for asking this question!
It would be greatly appreciated if you thanked me and marked me as the brainliest!
Have an amazing day.
The energy transformation which produces electricity and is least likely to
negatively impact the environment is generating electricity from a solar
panel system.
Generating electricity from solar panel involves the use of solar energy from
the sun to generate electricity . This type of energy doesn't emit any type of
harmful radiation or release toxic compounds into the atmosphere which
makes it the least likely to negatively impact the environment.
Other options emit any type of harmful radiation or release toxic compounds
into the atmosphere which makes option D the most appropriate.

Explanation:
Many of the lunar craters are due to volcanic eruptions true or false
Answer:
false
Explanation:
Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon's surface is covered with thousands of craters. ... It also has very little geologic activity (like volcanoes) or weathering (from wind or rain) so craters remain intact from billions of years.
