What would happen if the sand dunes in an area were destroyed?

Answers

Answer:

Then everything around the sand dunes are destroyed. It's like a domino effect.

Explanation:

Sand dunes are very helpful in coastal management. Destruction or destabilization of sand dunes will make us it hard to survive from storms and destruction of some vegetation also.

What is sand dunes?

Shorelines and desert landscapes frequently have sand dunes. Highly specialized plants and animals, especially rare and endangered species, find habitat on dunes.

Sand dunes offer essential ecological habitat as well as natural coastal defense against storm surge and strong waves, preventing or minimizing coastal flooding and structural damage. They serve as sand storage sites as well, delivering sand to beaches that have degraded.

Human activity, both purposeful and unintentional, endangers dunes Significant dune protection projects are run by nations like the United States, Australia, Canada, New Zealand, the United Kingdom, and the Netherlands.

Which material absorbs the MOST solar radiation? a.Sand b.Grassy Field C.Fresh snow d.Forest

Answers

It would be D. Forest cause of how many trees and plants there are in a forest

Forest absorbs most of the solar radiation. Therefore, option (d) is correct.

What are solar radiations?

Solar radiation can be described as electromagnetic waves coming from the sun and comes in three major types: visible light, infrared light, and ultraviolet light.

The electromagnetic spectrum has seven different types of light, listed from lowest frequency to highest: radio waves, microwaves, IR light, visible light, UV light, X-rays, and gamma rays. Solar radiation is light from the sun that can be categorized by its frequency and wavelength.

Solar irradiance can be described as the power per unit area received from the Sun in the form of radiation in the wavelength range and is measured in watts per square meter.

This may be measured in space or at the surface of the earth after atmospheric absorption and scattering. The forests have plants and trees which absorb the most solar radiation.

What do the periods in the periodic table tell us?

Answers

Answer:

When you look at the periodic table, each row is called a period (Get it? ... All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons.

Explanation:

Periods are called the horizontal line of the periodic table.Each period is consistent with the progressive occupancy of the orbitals in an atom valence shell. Longer periods correlate to the occupancy of the d subshell orbits.All elements have the same number of atomic orbits during a period.A row of chemical components would be a period inside the periodic table.Every following element in the same period has more protons than its predecessor and is less metallic.It enables quick reference to element information, such as atomic mass and chemical symbols. The schedule of a periodic table also allows scientific researchers to see patterns in element characteristics, such as electronegativity, ionizing energy, and nuclear radius.

Dr. Grey performed an experiment to test how temperature affects activity levels in mice. She put one group of mice in a cold environment and another group of mice in a hot environment. Everything else about the two environments was the same, including the type and amount of food and water. She allowed the experiment to last for a few generations of mice and tested the activity levels of the different groups. There was no change in the activity levels of the mice, but she noticed that the mice in the cold environment had much darker, thicker fur than the mice in the hot environment. What scientific question could she ask based on her results? A. Does temperature have an effect on fur color and thickness in mice? B. Do the mice in the cold environment run faster than the mice in the hot environment? C. Which group of mice is the most attractive? D. Does food type have an effect on fur color and thickness in mice?

Which of these events moves small pieces of rocks away from where they originally formed?
a Deposition

b Weathering

c Erosion

d Oxidation

Answers

Answer:

b

Explanation:

Answer:

Option C

Explanation:

Lets use the process of elimination to find the answer to this question. It's not option B because weathering is the breaking down of rocks through things that the Earth atmosphere comes into contact with like rain or living organisms, it's not option A because deposition is using bodies of water like rivers to lay down and compact rocks together using the strength of the stream. It's not option D because oxidation is a type of chemical reaction that has nothing to do with moving rock particles, leaving option C therefore it is your answer.

It is mostly contained in the arid area between the Rocky Mountains to the east and the fertile coast of the Pacific Ocean to the west. Researchers estimate that the desert is between 500,000 and 730,000 square miles.Differences of latitude, elevation, climate, topography, vegetation, soil, and human use have divided the desert into a cold region and a hot region. The cold region of the desert is known as the Great Basin Desert. This area covers almost all of Nevada, western Utah, and sections of the neighboring states. South of this basin is the Mojave Desert, which is the hot region of the North American Desert. This area covers much of California, southern Nevada, and some of Mexico.As a desert, the area is arid because of high evaporation, extreme temperatures, high winds, localized storms, and sun-beaten land. Life in the desert is a struggle for humans. People do live in this desert, but the pockets of people are dispersed and isolated. Native Americans and European settlers have added to the population of the region. Despite the harsh conditions, a surprising number of plants, animals, and reptiles make the desert their home. In fact, some species can only be found in the desert.What evidence does the author use to support the idea that there are people who live in the desert?
