how does the water cycle sustains life
plz help! !!
Water is constantly being cycled between the atmosphere, the ocean and the land. This cycling is a very important process that helps sustain life on Earth. When the sun heats water, the water evaporates or changes to water vapor. Water vapor rises and condenses or changes back into liquid water droplets.

In the context of this graph, what do the slope and y-intercept mean?
Answer: The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.
what is the molarity of a solution in which 10.0 g of AgNO3 is dissolved in 5 L of a solution
Answer:
no of moles = given mass/molar mass
no of moles = 10/169.87 =0.058moles
molarity = number of moles of solute/volume of solution in litre
molarity = 0.058/5
molarity = 0.0116

Which is an example of geologic evolution?
Answer:
A gradual change in the shape of the continents.
Explanation:
An example is tropical plant fossils are found in the Artic.
An example of geologic evolution is a gradual change in the size of continents.
Geological evolution is the process of gradual change and events in antiquity that include the steps to create the Earth.
At first, there was extreme volcanism, later the planet cooled to create the crust. Also, condensed water vapor formed the oceans and seas.
The geological history of Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy).
Geological evolution studies the shape of the globe, how it formed, and the relationships of the different eras and the matter that changed during them.
Therefore, An example of geologic evolution is a gradual change in the size of continents.

A balloon has a volume of 31.8 L at a temperature of 46 degrees C. What is the new temperature
of the balloon in degrees C if the volume is changed to 49.2 liters?
Round answers to 0.1 decimals
Answer:
The new volume will be
0.7 L
Explanation:
This is an illustration of Charles' law, some of the time called the temperature-volume law. It expresses that the volume of a gas is straightforwardly corresponding to the Kelvin temperature, while pressing factor and sum are held steady. The condition is V 1 T 1 = V 2 T 2 , where V is volume and T is temperature in Kelvins. Known V 1 = 0.5 L T 1 = 20 ∘ C + 273.15 = 293 K T 2 = 150 ∘ C + 273.15 = 423 K Obscure V 2 Arrangement Revise the condition to confine V 2 . Substitute the known qualities into the condition and address. V 2 = V 1 T 2 T 1 V 2 = ( 0.5 L × 423 K ) 293 K = 0.7 L adjusted to one huge figure

Explanation:
Matter can exist in three states namely: solid, gas and liquid. These three states are individually unique because they possess different properties or characteristics. Matter consists of particles, which behave differently in the different states.
Particles of a liquid e.g water, ethanol etc. will move freely about in the container it is placed but in close contact with one another. This means that the particles move freely while still attached to one another. This accounts for the reason liquids are said to FLOW.

Explanation:
Atmospheric rivers are relatively long, narrow regions in the atmosphere like rivers in the sky that transport most of the water vapor outside of the tropics. Not all atmospheric rivers cause damage, and most are weak systems that often provide beneficial rain or snow that is crucial to the water supply.

How many molecules are in 6.20 moles of CaCO3?
1 mole is equal to 1 moles CaCO3, or 100.0869 grams.
What is mole?A mole is just a measuring scale. In reality, it's one of the International System of Units' seven foundation units (SI). When already-existing units are insufficient, new ones are created.
The mole is a SI unit that is used to quantify any quantity of a substance. The word "mole" is shortened to "mol".
A mole consists of precisely 6.022140761023 particles. The "particles" could be anything, from tiny things like electrons or atoms to enormous things like stars or elephants.
Therefore, 1 mole is equal to 1 moles CaCO3, or 100.0869 grams.
