The correct answer is - chemical weathering.

The deserts are in general covered with sands. These sands are the result of weathering, mostly caused by the mechanical weathering of the wind. With the process of weathering of some of the minerals are created another minerals, like the iron oxide, which is possible only if the weathered minerals contained iron of course. Because the iron naturally has a reddish color, as the sends accumulate more and more, the desert starts to get that distinctive reddish coloration of its landscape.

Human activities including pollution, oil spills, global climate change, and over-exploitation of resources are the most damaging to the Earth's ecosystems. These activities are causing unprecedented changes to the environment and upsetting the delicate balance of our ecosystems, leading to potential collapse and irreversible damage.

Among the many human activities that have been damaging the ecosystems of the earth, the most damaging have arguably been pollution, oil spills, global climate change, and over-exploitation of resources. These activities have caused unprecedented changes to Earth's environment, altering ecosystems to the point where some may be in danger of collapse. We have seen alterations on a global scale such as depletion of the ozone layer, damage from acid rain, and changes from global climate change.

The technologies used to enhance human comfort, such as the harnessing of the energy contained in fossil fuels, have had significant negative impacts on our environment. And while interventions like agriculture and dam construction can support human settlements, they also result in habitat destruction and damage to the delicate balance of our ecosystems.

This is compounded by overharvesting, a process where humans extract more resources than an ecosystem can sustainably produce. This behavior has resulted in damming of rivers, redirection of water flows, habitat loss, and even species extinction.

In conclusion, various human activities are collectively and negatively impacting our ecosystems, causing disruptions and potential irreversible damage that underscore the need for us to understand these impacts and take steps to protect our environment.

Ik for sure number 1 is TRUE

This is a true statement.

Europe and Asia occupy the same landmass, forming a large landmass known as Eurasia. Notably, continents have shifted and moved throughout Earth's history, originally being part of the supercontinent Pangaea.

The two continents that occupy the same landmass are Europe and Asia. These two continents together form a large landmass called Eurasia. This term, 'Eurasia', is often used to refer to the combined continental landmass of Europe and Asia.

In the past, during the time of the supercontinent Pangaea, many continents that we now know as separate were all part of the same landmass. A scientist named Wegener conceived the idea of continental drift in 1910 when he observed similarities between the shapes of the continents, fossil evidence, and certain animal species on different continents. He proposed that these similarities were due to the continents once being part of a larger supercontinent, Pangaea.

Of course, continents have changed and moved throughout Earth's history. For example, the African plate once bumped into the Eurasian plate under great pressure, lifting mountains such as the Alps.

Answer:

The magnetic field changes every time it erupts along the mid-oceanic ridge and also these rocks helps in determining the age of the rocks.

Explanation:

Due to the constant plate tectonic activity, the rocks are constantly affected and are erupted along the mid-oceanic ridge where seafloor spreading takes place. These rocks forms here are the igneous basaltic rocks, and when cools after eruptions, it records the polarity of the magnetic field of the earth. The successive polarity is oriented in opposite directions, in the form of stripes which are very prominent. This data also helped in determining the relative age of the rocks of oceanic crust. The mid-oceanic rocks are younger whereas those that are formed further away from it are the oldest.

Cities form due to a combination of socio-economic, political, and technological factors, creating opportunities and fostering a diverse urban culture. However, they also bring challenges such as providing services for growing populations and managing the consequences of poverty and slums.

Cities form due to various socio-economic, political, technological, and environmental processes and have dramatic effects on culture by creating opportunities for jobs, education, and cultural activities, yet also presenting challenges such as urban poverty and slums. Urbanization is driven by the desire to reduce commuting time and expenses, and improve access to opportunities. However, with high population growth, cities often face challenges such as providing adequate services and housing, which can lead to the development of slums.

Technological advances and industrialization have contributed greatly to urban growth, with cities often replacing agrarian culture. This shift typically involves changes in social interactions and economic exchanges, as urbanization often meant replacing barter and personal economic relationships with cash transactions and anonymous manufacturing processes. The concentration of wealth and opportunity in cities also accentuated the social and economic divide between the wealthy and the poor.

Finally, cities affect culture by being hubs for diversity, thereby fostering diverse social communities. This diversity can lead to an expansion of cultural institutions like museums, theaters, and restaurants, offering a vibrant urban culture. At the same time, cities bring complexities such as high crime rates and pollution, evoking strong opinions among residents and non-residents alike.

For example, in the United States, indigenous populations are often identified as Native Americans or American Indians; in Hawaii, the preferred term is Hawaiians; while in Mexico they are addressed as la gente indígena de México (the indigenous people of Mexico); and in Australia the terms Aboriginal peoples, Torres Strait Islander peoples, and Indigenous Australians are used.

It's important to note that the terminology used to describe indigenous groups not only identifies their geographic origins but also underscores their rich historical, cultural, social, and political identities. The preferential use of certain terms over others often reflects the continued struggle of indigenous communities for recognition, sovereignty, and rights amidst colonization and systemic disenfranchisement.

Changes in the earth's orbit allowed the ice sheets to extend over Canada, resulting in nearly all of Canada and portions of the northern United States being buried by thick glacial ice around 15,000 years ago.

The Laurentide Ice Sheet was a vast sheet of ice that covered millions of square miles, including much of Canada and a major chunk of Northern America, several times throughout the Quaternary glacial epochs, from 2.58 million years ago to the present.

Giant ice sheets have grabbed the world at least 15 times in the last 2.5 million years. Glaciers carved out around one-third of the earth's landmass. They spanned from present-day New York to Montana, and from Ohio to Hudson Bay, Canada, and were up to 2 miles thick at times.

Due to changes in the earth's orbit, the ice sheets were able to spread across Canada, burying virtually all of Canada and parts of the northern United States under thick glacial ice roughly 15,000 years ago.

Therefore, option B is correct.
