What has been the main cause of climate change over the past 100 years? How do we know humans are causing the climate to change, rather than natural causes?

Chemical rocks are identified by their mineral compositions, essential in determining their types, such as limestone and rock salt. Detrital rocks, conversely, are classified by the size and sorting of their grains, with examples including sandstone, which is known for its sand-sized particles.

The identification of chemical rocks versus detrital rocks is primarily based on their mineral compositions and grain sizes, respectively. Chemical rocks, such as rock salt and limestone, are usually identified by their mineral compositions. These rocks are precipitated from water saturated with dissolved minerals, making their composition the main factor in identification. For example, limestone is identified by its primary composition of calcite. On the other hand, detrital rocks, also known as clastic rocks, are identified based on the size, shape, and sorting of their grains. These rocks form from pieces of bedrock or sediment derived primarily by mechanical weathering, with grain size being a key factor in their classification; for instance, sandstone is identified by its sand-sized particles.

All of the above except "formed from the remains of dead plants."

Metamorphic rock is formed by heat and pressure from any type of rock (igneous or sesimentary) and is part of the rock cycle.

Metamorphic rock is constituted from igneous rock, sedimentary rock, heat energy and pressure level, and is also an element of the rock cycle.

Metamorphic rocks were defined as once sedimentary rocks that were altered by aggravated heat and/or pressure within the Earth's layer. They have a crystalline texture and are frequently “squashed”.

Metamorphic rock is a factor of the rock cycle that is formed from igneous rock, sedimentary rock, energy, and physical phenomenon.

Answer:

To find the area of the triangle shown in the picture, we need to find the height and the base.

The length of the height should be:

cos45° = BC/AB

=> BC = AB · cos45° = 24 · cos45° = 12√2 (ft)

From the information provided, we can calculate ∠CAB which is 45°, therefore ΔABC is an isosceles triangle, meaning that BC = AC = 12√2 (ft)

The area of the figure is:

A = bh/2 = (12√2)²/2 = 144 (ft²)

Answer:

Brings in warmer and drier winters

Explanation:

El Nino is one of the two parts of the natural weather phenomenon known as the Southern Oscillation. El Nino basically is a warming up of the waters of the eastern part of the Pacific, pilling up warmth and moisture. As it spreads out, El Nino starts to impact whole continents and even has a global impact on the climate. While South America, Central America, and up to California, there's a significant increase in the rainfall, thus also slightly lower temperatures because of it, the northwestern part of the Pacific experiences the total opposite. The winters in the northwest are actually warmer on average and drier, resulting much less snowfall. This affects badly the economy of this parts as there are numerous winter tourist centers, but when El Nino is in action they do not have enough snowfall, or even when they get it often melts very quickly.

Answer:

Tropical forest

Explanation:

The tropical forest is an ecological community that is characterized with temperatures throughout all of the year, as well as high amount of precipitation and humidity. These ecological communities are located at the equator and near the equator, thus on the very low latitudes. They are home to more than half of the animal and plant species on planet Earth. They have the highest concentrations of living organisms, having also the highest diversification on the planet. The tropical forests are fascinating in every possible way, and it is a shame that the research in them is still largely descriptive, because the terrain and the conditions are extremely tough for any other method to be put in practice.

When two oceanic plates coverage the denser will subduct under the plate that is less dense creating a deep sea trench at the point of subduction. As the subducted plate goes deeper into the mantle the mantle material above starts to melt to become magma

3, 4, and 5 are all formed usually when magma cools below the surface, deep in the Earth's crust, or cool in the crust but soon re-heat to creat an explosive "bomb" lool

Volcanic necks, Batholiths and Dome Mountains are the features formed when magma cools beneath the Earth’s surface.

Explanation:

Magma chambers correspond to the surface in reservoirs below which Magma is stored.  “Stocks, laccoliths, sills” are some of the Intrusive features that are formed as a result. The type of volcanic landforms is decided by the cooling of magma either within the crust or above the crust.  

This may result in either extrusive or intrusive landforms. The feature is also known as dynic volcano. The final stage is the formation of the magma, cooling of it, and then becoming hard.

The convection cell in the mantle is essentially the self-sustaining, constant movement of the magma inside this layer. This works in a very simple way. The hotter magma is less dense, so it is pushed upward toward the crust above it, while the cooler magma is denser, and it moves downward where it gets hotter, and the process goes on and one. The magma that goes upward toward the crust, manages to push through the thinner and cracked crust between the plates that move away from each other, thus on the divergent plate boundaries. As the magma penetrates through the crust it manages to get to the ocean floor, thus causing volcanic activity. This magma cools of very quickly and creates new crust. Because the magma constantly rises up and creates new crust, the crust piles up and forms an underwater mountain of volcanic origin that constantly has volcanic activity because of the rising magma. This volcanic underwater mountain range is called mid-ocean ridge.

Convection cells in the mantle heat and move the semi-liquid mantle, causing plates in the Earth's crust to move. At mid-ocean ridges like the Atlantic Ocean, the plates move apart, providing an outlet for the rising hot mantle material, leading to volcanic activity and formation of new crust material.

Convection cells in the Earth's mantle result in volcanism at the mid-ocean ridge through a sequential process. First, heat from the Earth's core causes the semi-liquid mantle to heat, decrease in density, and rise. Convection cells gradually form, as the hotter and lighter mantle material moves upwards, while the cooler and denser material sinks.

These convection currents exert force on the tectonic plates located in the Earth's crust, causing them to move. Particularly, at the mid-ocean ridges, such as the Atlantic Ocean, the force from the convection cells causes the tectonic plates to move apart from each other along rift zones. This movement creates a gap, through which the ascending hotter mantle material can emerge onto the ocean floor.

The emergence of this hot mantle material at mid-ocean ridges leads to volcanic activity, as the molten rock or magma breaks through the crust, cools, and solidifies to form new crust material. This entire process is a key factor in the formation of the Earth's topological features such as oceanic trenches, oceanic ridges, and volcanoes.

Plateau

Explanation:

A plateau is an area of relatively high ground.

"The area of elevated flat land is called a plateau.

A plateau is a flat, elevated landform that rises sharply above the surrounding area on at least one side. It is often referred to as a tableland. Plateaus can be formed by a variety of geological processes, including volcanic activity, erosion, and tectonic uplift. They are found on every continent and can vary greatly in size and elevation. Some well-known examples of plateaus include the Tibetan Plateau in Asia, the Colorado Plateau in North America, and the Deccan Plateau in India. Plateaus are important for human activities such as agriculture, settlement, and mining due to their relatively flat terrain and often fertile soils."

Final answer:

Agricultural advancements have enabled cultures to become more self-sufficient by increasing food production, creating surpluses, and allowing for labor specialization, which has led to more complex societal structures and cultural developments.

Explanation:

Agriculture was the key development in the rise of sedentary human civilization. From its beginnings with simple tools, such as a pointed stick, to more complex technologies like the plow, agricultural advancements have had profound effects on human societies. Initially, people used simple tools to break up the soil, but when they harnessed animals to pull plows, productivity increased significantly.

This allowed a family to produce more than enough food for themselves, contributing to the creation of food surpluses and enabling the rise of settled communities. The invention of the plow approximately 5,000 years ago marked another critical moment in agriculture by increasing food supply and supporting population growth.

The Green Revolution introduced high-yielding varieties of grains, like wheat, corn, and rice, along with the use of fertilizers, pesticides, irrigation, and new machinery. These innovations further enhanced the ability of cultures to be self-sufficient, lifting millions of subsistence farmers above the survival level. With the advent of such agricultural improvements, some countries like China and India became self-sufficient in their basic food needs, and others such as Thailand and Vietnam emerged as leading exporters of rice.

Moreover, improved agricultural methods allowed for the specialization of labor within societies. As not everyone had to farm, others could focus on building structures, creating tools, or engaging in trade. This division of labor ultimately led to more complex societal structures, including the development of social hierarchies and cultural advancements such as math, writing, and science.

Short term global cooling and more rainfall

Explanation:

The eruption of the volcano Mt. Pinatubo in the Philippines managed to propel lot of ash and debris into the atmosphere. The atmosphere is not static, and the air movement manages to disperse these aerosols over much wider area over the planet. Since the aerosols manage to partially block the sunlight, the global temperatures would suddenly drop, thus there will be cooling off of the weather conditions across the planet. Also, the aerosols manage to contribute to more condensation oft he water vapor, and that results in more precipitation, so there has also been more precipitation around the world. The effects have been short term though, as the amount of aerosols propelled into the atmosphere has not been that big so that it can cause long term changes of the climate.

Answer:

Location and Climate

Explanation:

Biodiversity: The variety of life in the world or in a particular habitat or ecosystem.

A rainforest has more biodiversity than a temperate forest because of the rainforest's habitat, location and climate.

Due to the fact that a rainforest contains swamps, jungle, land, tree and underground life options for a wide variety of animals, that opens the door for more animals to come in and live in the rainforest.

The climate is adaptable and easy to get to know (to animals), so that will cause animals to stay and populate in certain areas.

A temperate forest does not contain many options for where to live. yes, there are many options with what we have, but the range for what animal can live in the temperate rainforest is very specific. If you are a water animal, you can't live here. If you are a really big animal, you can't live here. If you are a slow animal, you can't live here.

Everything depends on habitat, ecosystem, land and climate.

Mordancy.

the most harmful effects of DDT is nerve damage. this results in hair loss, muscle atrophy, disorientation, cancer.

Final answer:

DDT is known to cause environmental harm through bio magnification, affecting higher-level organisms like birds with fragile eggshells and leading to declines in their populations. Classified as a Persistent Organic Pollutant, DDT accumulates in living tissues, potentially causing infertility and cancer. Its detrimental impacts eventually led to its ban in the 1970s, with subsequent recoveries in affected bird populations.

Explanation:

The use of DDT has been associated with numerous harmful environmental and ecological effects, particularly on wildlife. Bio magnification is a significant issue with DDT, as this chemical distributes up the food chain, affecting various species, especially those at higher trophic levels. Notably, birds of prey such as eagles, falcons, and pelicans have been severely impacted, as their eggshells became too thin and fragile due to the accumulation of DDT, leading to decreased populations due to egg breakage and failure to reproduce.

Furthermore, the persistence of DDT in the environment, a characteristic that made it an effective pesticide, led to its classification as a Persistent Organic Pollutant (POP). POPs are known for their long-standing presence in the environment, with the ability to accumulate in the tissues of living organisms, potentially causing infertility and an increase in the prevalence of certain cancers. The extensive use of DDT also resulted in ecological imbalances and resistance among malaria parasites and agricultural pests, diminishing its effectiveness and necessitating alternatives.

After recognizing its detrimental effects, the use of DDT was banned in the United States in the 1970s. This led to the recovery of various bird populations. However, the negative legacy of DDT as a pollutant still serves as a cautionary tale about the need for careful consideration and environmental impact assessment of pesticides and other industrial chemicals before widespread use.

Liechtenstein

Explanation:

Liechtenstein is one of the smallest countries in Europe, but also in the world. It is located between the two more famous Alpine countries, Switzerland and Austria. The capital of the small Alpine country is Vaduz, which is the center of all pretty much everything in the country. Maybe surprisingly, but Liechtenstein is one of the best countries for living in the world, having one of the highest GDP's per capita in the whole world, leaving the large economies trailing far behind it in that department. The country has a very strong economy, and it is based around the service sectors, mostly the banking, which brings in the majority of the income in the country. It was once a heaven for the rich people to hide their money from the public eye, but that is not the case anymore, and Liechtenstein is a country that left that in the past, being a member of pretty much every organization that a country would like to be in the present.

The landlocked country in Europe that is bordered by Switzerland and Austria is Liechtenstein. It is a ministate part of the Alpine Center, which also includes Switzerland, with its diverse linguistic culture and Austria known for its high standard of living.

The landlocked country in Europe that is bordered by Switzerland and Austria is the mini-state of Liechtenstein. This ministate is nestled between these two countries, in a region dominated by the Alpine ranges. Liechtenstein is considered part of the Alpine Center, which includes Switzerland and Austria, bearing close geographical and economic ties with these nations.

Switzerland and Austria are notable countries in the Alpine region. Switzerland is divided into 26 cantons and has four official languages—German, French, Italian, and Romansh—reflecting its multicultural ties. Its capital is Berne, and it has a population of over 8 million people. Austria, on the other hand, is similar in area to the US state of South Carolina and has a population of around 8.7 million. It has a social market economy and a high standard of living, with Vienna as its capital city.

The theories about the Earth being the center of the universe, and the Sun being the center of the universe are very similar. The theory about the Earth being center of the universe, or the geocentric theory, suggests that the Earth is the largest object, located in the center of the universe, and every other object such as the Sun, Moon, planets, stars are orbiting around it. The theory is wrong, and the only thing that it got somewhat right is that the Moon is orbiting around the Earth.

The theory that the Sun is the center of the universe, or the heliocentric theory, suggests that it is the Sun that is the center of the universe, not the Earth. According to this theory, the Sun is the largest object, it is located in the center of the universe, and all the objects such as the Earth and the other planets, stars, moons, are all orbiting around it. The theory is wrong, though it has to be said that it is a big step forward, and while it is not accurate about the universe as a whole, it is very close to how the solar system works.
