How has society and environment have changed by use of fertilizers containing nitrogen?

The use of nitrogen-containing fertilizers has led to increased crop yields, which has helped to feed a growing global population. However, overuse of nitrogen fertilizers can lead to water and air pollution, as excess nitrogen can runoff into waterways and contribute to greenhouse gas emissions. Sustainable farming practices and proper fertilizer management are essential to minimize the negative impacts of nitrogen fertilizers on society and the environment.

What causes use to have seasons?

Seasons are caused by the tilt of Earth's axis as it orbits the Sun. The angle of the tilt affects the angle at which sunlight hits the Earth's surface, leading to variations in temperature and daylight hours throughout the year. This tilt results in different amounts of sunlight reaching different parts of the globe, creating the four seasons.

How does sand and fire make glass?

When heated to high temperatures, sand melts and fuses together to form glass. The heat from the fire melts the sand, turning it into a molten liquid that can be shaped and molded. When the glass cools down, it solidifies into a transparent, hard material.

Will there be no water in 2050?

There will be definitely still be water in 2050. And in 20500, 205000, and 2050000. It's not until we get into the billions territory where there's a significant doubt that liquid water will still exist SOMEWHERE on Earth.

Which of the following minerals is most resistant to being scratched?

Diamond is the most resistant to being scratched as it is the hardest mineral on the Mohs scale with a rating of 10.

What other thing can cause physical weathering besides the process of thawing and freezing?

Other factors that can cause physical weathering include the actions of wind, waves, and plant roots. Wind can carry abrasive particles that wear down rocks, while waves can crash against coastal rocks and break them apart. Plant roots can also grow into cracks in rocks, expanding and contracting, causing them to break apart.

How thick is the lithmosphere?

The lithosphere varies in thickness, ranging from about 5 to 100 kilometers (3 to 62 miles) beneath the Earth's surface. It is thinnest beneath the oceans and thicker beneath continents.

What move by giving particles a circular motion and are generated by energy that travels outward from epicenter?

Seismic waves are the move generated by energy traveling outward from the epicenter in a circular motion, causing particles to oscillate. These waves are responsible for the shaking and ground motion during an earthquake.

What is the effect that causes objects to move in curved direction due to the earths rotation?

The Coriolis effect is the phenomenon that causes objects to be deflected in a curved path due to the rotation of the Earth. It influences the movement of air masses, ocean currents, and objects over long distances, leading to patterns such as the rotation of hurricanes and the direction of ocean currents.

Why does rocks not visibly vibrate but particles that make up rock constantly move?

The reason rocks do not visibly move is because the rock particles are so small because they were broken down

Can a short pea plant ever be produce from crossing two tall pea plants?

No, the short pea trait is recessive and the tall pea plant trait is dominant. This means that if the plant is a hybrid, it has to be a tall pea plant. The dominant traits "mask" the recessive traits. The plant take one trait from their mom and one from their dad. If either the mom or the dad was not a tall, not hybrid pea plant then their kids would have to be tall be cause they would have one dominant, tall trait

What is it called when an object sinking in water pushes an blank volume out of the way?

This phenomenon is called displacement. When an object sinks in water, it displaces an equivalent volume of water equal to its own volume. This displacement results in the upward force known as buoyancy, which helps objects float or sink in a fluid.

What is a mass movement of rock and soil suddenly slipping down a slope in one large mass?

A mass movement of rock and soil suddenly slipping down a slope in one large mass is called a landslide. This phenomenon can be triggered by factors such as heavy rain, earthquakes, or human activities that destabilize the slope. Landslides can cause significant damage to property and pose risks to human lives.

What is Entrusive?

Entrusive refers to the process of magma or molten rock being forced into surrounding rock formations. This can result in the formation of features such as dikes, laccoliths, and batholiths. Entrusive igneous rocks are formed from this process.

Do hurricanes affect earths surface or the ocean?

The correct answer to that question is BOTH, if the hurricane comes ashore.

Hurricanes derive their strength from the temperature of the ocean. As the heat from the water rises, the strength of the storm increases. As the storm increases in strength, it cools the surface of the ocean with wind, rain and (if conditions are right) hail.

When hurricanes move over shallow water, they churn up sediments on the ocean floor, which in turn provide a source of nutrients for a variety of marine life. When very strong, they can also destroy coral reefs, which have a negative affect on the many creatures that depend on the reefs for their survival.

Hurricanes that achieve "landfall" cause many problems for vegetation, wildlife, coastal features (due to wind and water errosion), transportation, communication, structures and humans.

The major threats from hurricanes that come ashore are:

Very strong winds (70mph to 200mph) that may damage ships, marinas, knock down power lines, buildings and trees.

Storm surges and heavy rains, that cause flooding, that can destroy; beaches, businesses, homes, crops, roads and sometimes human life.

Who are people who study maps called?

cartography or for the person that makes the maps that would be a cartographer

Is Detroit a formal region or a vernacular region?

Detroit is the "formal" name of a city. This makes it a formal region. When people talk about Detroit, they are often talking about places that are not actually in Detroit, but in the Metro area around Detroit. In this sense it is a vernacular region.

How were the floods in Bangkok created?

The floods in Bangkok were created by a combination of heavy rainfall, a high volume of water flow from upstream areas, inadequate drainage systems, and urban development that reduced natural water absorption areas like wetlands and fields. Additionally, the city's low-lying geography and subsidence contributed to the extent of flooding.

Is The Earth's crust Of Uniform Thickness?

No, the Earth's crust is not of uniform thickness. It is thicker beneath continents and thinner beneath oceans, resulting in variations in crustal thickness across different regions of the world.

What is the luster streak and hardness of a geode?

Its simple, see a lot of people would have guessed a geode is a mineral or a gem. But its not. Geode is a sedimentary rock so instead of looking for the luster steak and hardness look facts on it like from its sedimentary form. A geode might have minerals in it, but that doesn't make it a mineral itself.

The older theory of continental drift suggested?

that the continents were once all connected as one supercontinent, called Pangaea, which broke apart and drifted to their current positions over millions of years. This theory eventually led to the development of the theory of plate tectonics to explain the movement of Earth's large landmasses.

What is ironstone used for?

Ironstone is a type of stoneware ceramic that is often used to make tableware such as plates, bowls, and serving dishes. It is valued for its durability and chip resistance, making it ideal for everyday use in the kitchen and on the dining table. Additionally, its classic and timeless appearance makes it a popular choice for both casual and formal dining settings.

Which mass movement is the greatest risk to humans?

Climate change is considered the greatest risk to humans as it is causing widespread environmental degradation, extreme weather events, sea level rise, and loss of biodiversity, which ultimately impact human health, livelihoods, and food security. mitigating its impact requires global cooperation and significant reduction of greenhouse gas emissions.

What is the French word which means a sense of place and encompasses all the climate and geographic features in making wine?

'Le terroir' (masc.). It refers to any geographically limited area, where soils share the same geological characteristics, and the same climate.

What is the diffence in diameter between the smallest and largest planet?

The smallest planet is Mercury with a diameter of about 4,880 kilometers, while the largest is Jupiter with a diameter of about 139,820 kilometers. Therefore, the diameter difference between the smallest and largest planet is approximately 135,940 kilometers.
