Why is the environment more important than the economy?

Answers

We can’t live without an environment

But we can without an economy

The environment is more important than the economy because it provides us with clean air and water, healthy food, and preserved nature. These all components benefit human health and result in far more economic benefit than the economic cost.

What do you mean by Environment?

The environment may be characterized as the sum total of all sorts of living and non-living elements and their effects which consequently influence human life and other animals. There are basically two factors that contribute environment, i.e. biotic and abiotic factors.

The environment is more important than the economy because it delivers forests, rivers, oceans, and soils that provide us with the food we eat, the air we breathe, and the water we irrigate our crops with. We also rely on them for numerous other goods and services we depend on for our health, happiness, and prosperity.

A forecast indicates a dew point temperature equal to the air temperature. What does this information imply?
A. Relative humidity is 0%, and there is no chance of rain.
B. Relative humidity is 100%, and it may rain.
C. Relative humidity is 0%, and it may rain.
D. Relative humidity is 100%, and there is no chance of rain.

Answers

Answer:

B

Explanation:

I hope this helps :) :)

As the dew point temperature equal to the air temperature this implies that the relative humidity is 100%, and it may rain. The correct option is B.

What is relative humidity?

Relative humidity (RH) is a percentage ratio of the amount of atmospheric moisture present to the amount that would be present if the air was saturated.

If the air is completely saturated at a specific level, the dewpoint temperature is the same as the actual air temperature, and the relative humidity is 100%.

There would be no clouds, precipitation, or fog if humidity did not exist. Humidity is simply the amount of water vapor in the air that is required to form rain. Furthermore, water vapor retains heat in the air.

Since the dew point temperature is equal to the air temperature, it may rain and the relative humidity is 100%.

Thus, the correct option is B.

Answers

A. applied force is a contact force

Answer:

A: Applied force

Explanation:

The rest of them are non-contact forces.

A contact force is any kind of force that requires contact to occur.

So:

Applied force is a contact force because they occur ONLY during contact with each other.

Gravitational force is not a contact force because they occur even when they're not in contact with each other.

Electrical force is not a contact force because they also occur even when they aren't in contact with each other.

Magnetic force is not a contact force because they pull/push on objects without touching them.

In one to two sentences, explain how the shorelines can affect weather.

Answers

Answer:Coasts are sensitive to sea level rise, changes in the frequency and intensity of storms, increases in precipitation, and warmer ocean temperatures.

The ocean warms and cools more slowly than the atmosphere, thus coastal or shorelines weather tends to be more moderate than continental weather, with fewer hot and cold extremes.

What is shorelines?

The shoreline refers to the place where a large body of water, such as ocean, lake, or river, meets the land. Evaporation from the ocean, especially in the tropics, creates most rain clouds, influencing the location of wet and dry zones on land.

The shoreline or coastal zone often experiences a unique weather which results into a very special climate. Coastal meteorology is the study of meteorological phenomena within about 100 km inland or offshore of a shorelines or coastline.

Thus, from above, it is explained how the shorelines can affect weather.

Dew point is the temperature at which the rate of condensation equals the rate of evaporation.

True
False

Answers

Answer:

Called the dew point temperature, the point of saturation is where evaporation equals condensation. Therefore, a cloud results when a block of air (called a parcel) containing water vapor has cooled below the point of saturation. Air can reach the point of saturation in a number of ways.

Explanation:

The statement "dew point is the temperature at which the rate of condensation equals the rate of evaporation" is definitely true.

What is Evaporation?

Evaporation may be characterized as a type of chemical process through which an element or compound transforms from its liquid state to its gaseous state. This can certainly be achieved by consistently delivering energy to the compound.

Dew point temperature is the temperature at which air must be cooled in order to become saturated with water vapor. This water vapor is a form of a gaseous component that intermingles with the liquid components which are formed through the process of condensation. At this point, the rate of condensation equals the rate of evaporation.

Therefore, the statement "dew point is the temperature at which the rate of condensation equals the rate of evaporation" is definitely true.
