Monarchs, such as royal families.
Answer:
Five largest cities in the US
1. Alabama
2. Alaska
3. Arizona
4. Arkansas
5. California
Explanation:
Physical features of these cities
1. Alabama: Montgomery is the state capital and site of many landmark civil rights events, like the Montgomery bus boycotts throughout 1955 and 1956 and the Selma-to-Montgomery March for voting rights in 1965.
The nation’s oldest baseball field, Rickwood Field, which opened in 1910, is located in Birmingham.
2. Arizona: Phoenix is the most populous state capital with approximately 1.5 million people living there. According to the National Climatic Data Center, the sun shines on Phoenix for 85 percent of its daylight hours.
3. Arkansas: Little Rock became the capital of the territory of Arkansas in 1821. The name “little rock” comes from the French explorer Bernard de la Harpe. In 1722, he saw rock formations jutting out from the Ouachita Mountains and named one group the big rock and the other the little rock.
4. California: this is the third largest city in the United States. California boasts mountains that are visible from just about anywhere in the state. Two main mountain ranges dominate: the Sierra Nevada and the Coast Range. The Coast Range runs from the northwest all the way down to the Mexican border, across 800 miles of terrain.
Answer:
The ozone layer is usually referred to as a blanket that protects the earth from the harmful incoming solar radiation. It is located in the Stratosphere layer but also there is another ozone layer in the troposphere, commonly known as the troposphere ozone.
The stratospheric ozone is considered to be good ozone because it is located at a high altitude and it directly acts as a shield protecting the earth from the solar radiation, which can cause various types of skin diseases and also can increase the surface temperature of the earth.
On the other hand, the troposphere ozone is considered to be bad as it is located near to the ground surface and is mainly comprised of the greenhouse gases, that are harmful to the atmosphere and also increases the surface temperature of the earth.
CFC is one of the greenhouse gases that are harmful to the atmosphere because CFC molecules are continuously hit by the solar radiations that breaks the bond between the carbon and chlorine, resulting in the production of a single Chlorine atom, which eventually breaks down down the ozone layer by reacting with it. This is how the CFCs depletes the stratospheric ozone.
The depletion of the ozone layer leads to the global climatic changing, affecting all the biotic and abiotic components of the earth. This is a long term effect. This global warming is a threat to destroy the earth, so preventive measures must be taken in order to reduce the causes and use of those substances that can lead to catastrophic changes.
Trees serve as a natural force to prevent erosion and hold soil together during rainfall and other periods of weather that might impact the integrity of the soil. However, trees were cut down to build a new shopping center there could be an increased flow of water to a river and also lead to great soil erosion nearby thus increasing the amount of sediment being deposited into the river. Also this new shopping mall could increase the pollutants in a river as well.
