-all
-50%
-75%
-10%

Answers

Answer 1

According to the Scientific American article on climate change solutions, coal supplies approximately 50% of the electricity used in the United States.

The correct option is B.

When fossil fuels are burned to produce power and heat, they release a significant amount of greenhouse gases that cover the Earth and trap solar radiation.

Fossil fuels, such as coal, oil, and gas, account for more than 75% of all greenhouse gas emissions and almost 90% of all carbon dioxide emissions, making them by far the biggest cause of climate change in the world.

To do this, countires shall stop relying on fossil fuels and start putting money into reliable, clean, accessible, and affordable alternative energy sources.

Although burning fossil fuels still produces the majority of electricity, cleaner energy alternatives are gaining popularity.

Thus, the correct option is B.

2: The camera uses an automatic film strip that transforms to digital.

3: The camera does it using magic.

4: The aperture slowly changes the digital image to a cloud-based image.​

Answers

The camera uses a light-sensitive chip or image sensor.

A digital camera work almost the same way as film cameras. Except, instead of using rolls of film made using light-sensitive silver halides, digital cameras have a sensor that's made of silicon. A digital camera's sensor has a grid of thousands of tiny "photosites" that are sensitive to light. The photosites are also called as pixels.

The newest cameras have sensors made up of millions of pixels. When a camera snaps an image, light streams through the lens and hits the sensor. The sensor absorbs the photons, measures the colour and intensity of the light, and turns that information into a long string of numbers.

To a computer, that long string of numbers is a set of instructions that tells it how to show the image, which is why we can transfer digital images to any camera, computer or smartphone and they always look the same.

Which of the following is true according to the theory of plate tectonics

Answers

According to the theory of plate tectonics, the Earth's lithosphere is divided into several large and small plates that float on the semi-fluid asthenosphere beneath them. These plates are constantly moving and interacting with each other, resulting in various geological phenomena. The theory of plate tectonics provides a comprehensive explanation for many Earth's features and processes, and the following statements are true based on this theory:

1. The Earth's lithosphere is divided into several tectonic plates: The theory of plate tectonics suggests that the Earth's rigid outer shell, known as the lithosphere, is broken into several distinct plates. These plates include major ones like the Pacific Plate, North American Plate, Eurasian Plate, African Plate, and many smaller plates.

2. The plates move due to convection currents in the mantle: The movement of tectonic plates is driven by convection currents in the underlying asthenosphere. Heat generated from the Earth's core causes these currents, which in turn exert forces on the plates, causing them to move.

3. Plate boundaries are associated with various geological activities: The interactions between tectonic plates occur primarily at plate boundaries. There are three main types of plate boundaries: divergent boundaries (where plates move apart), convergent boundaries (where plates collide), and transform boundaries (where plates slide past each other). These plate boundaries give rise to a range of geological phenomena such as earthquakes, volcanic activity, mountain building, and the formation of oceanic trenches and rift valleys.

4. Continental drift and seafloor spreading: The theory of plate tectonics explains the movement of continents over geological time. It suggests that continents are not fixed but have moved and are still moving due to the motion of tectonic plates. The process of seafloor spreading at divergent plate boundaries is responsible for the creation of new oceanic crust and the widening of ocean basins.

5. Subduction zones and the recycling of crust: At convergent plate boundaries, where one plate is forced beneath another, subduction zones are formed. Subduction zones are associated with the recycling of the Earth's crust, where old oceanic crust is pushed back into the mantle, melted, and reabsorbed into the Earth's interior.

What is the impact of coriolis force and latent heat on the development of tropical cyclone Eloise

Answers

The Coriolis force and latent heat play a crucial role in the development of tropical cyclone Eloise. The Coriolis force is responsible for the rotation of the Earth and the resulting movement of air masses. As warm, moist air rises and is forced to spin by the Coriolis force, it creates a low-pressure system.

This low-pressure system draws in more warm, moist air, which rises and cools, releasing latent heat. This latent heat release is essential for the continued development and intensification of tropical cyclones.

In the case of Eloise, the Coriolis force and latent heat contributed to the storm's rapid intensification. As the storm moved over warm ocean waters, it drew in more warm, moist air, which rose and cooled, releasing latent heat.

This release of latent heat caused the air to expand and rise further, creating a stronger low-pressure system. The Coriolis force then caused the air to spin, further strengthening the storm.

Overall, the Coriolis force and latent heat are essential factors in the development and intensification of tropical cyclones like Eloise. Understanding these processes can help us better predict and prepare for future storms.

Please select the best answer from the choices provided.

A
B
C
D

Answers

The  Factor that encouraged early humans to urbanize is option A. Adapting to climate changes.

Early humans' urbanization was primarily driven by factors such as sharing agricultural resources, creating governments, and sharing cultures. As people settled in one place, they started cultivating crops and domesticating animals, which led to an increase in food production. This, in turn, encouraged people to work together and share resources, promoting urbanization.

The establishment of governments helped manage resources and maintain order within growing communities. Governments also played a role in constructing public infrastructure, organizing defense, and regulating trade, all of which were essential for urbanization.

Sharing cultures was another factor that encouraged urbanization. As people came together in urban centers, they exchanged ideas, beliefs, and traditions, leading to cultural development and a more cohesive society.

In contrast, adapting to climate changes was not a primary factor encouraging early humans to urbanize. While climate changes may have affected the locations where people settled, the main driving forces behind urbanization were resource sharing, governance, and cultural exchange.

If Iceland was considered such a wasteland,
why did the Vikings want it for themselves?

Answers

Answer:

Iceland was not considered as a wasteland by the Vikings that settled in, but the name was given on purpose so that they avoid competition for it.

Explanation:

The Vikings were the first people to reach Iceland. They traveled from their homeland in Scandinavia into the unknown ocean water and eventually managed to reach a large island. Once they got to the island, they made it their base, but also sent expeditions further west, reaching Greenland, and even the North American mainland.

Being aware that there are other groups of Vikings waiting to set sail westward, the first group decided to trick them in order to get better land for themselves. This was done by naming the two large islands they discovered. The green and much more suitable for a living have been named Iceland, while the one covered with ice and much harsher was named Greenland. This made the later groups of Vikings think that Greenland is the better option and they got tricked. Iceland was not a wasteland by any means. It had a lot of timber, freshwater, and an abundance of fish and marine mammals as a food source.

Explain why Hard Wood considered to some is an unsustainable material. D&T

Answers

Hardwood is often considered to be an unsustainable material due to several reasons:

1. Slow growth rate: Hardwood trees take a long time to mature and grow to their full size, which means that they are not a renewable resource in the short term. It can take decades or even centuries for a hardwood tree to reach its full size and be ready for harvesting.

2. Deforestation: The demand for hardwood has led to deforestation in many parts of the world, especially in tropical rainforests. This has led to the loss of biodiversity and habitat for many species of plants and animals, as well as increased carbon emissions due to the destruction of forests.

3. Unsustainable harvesting practices: In many cases, hardwood is harvested using unsustainable practices such as clear-cutting, which can lead to soil erosion, water pollution, and other environmental problems.

4. Transportation: Hardwood is often transported long distances to reach markets, which contributes to greenhouse gas emissions and other environmental impacts.

As a result of these issues, many designers and engineers are exploring alternative materials for use in their products and projects, such as bamboo, cork, and recycled materials. These materials are often more sustainable than hardwood and can help to reduce the environmental impact of design and technology projects.

Explain the inequalities of the division of the north and the south.

Answers

The division between the North and the South refers to the historical and socio-economic disparities that existed in the United States before and during the American Civil War (1861-1865).

These inequalities encompassed various aspects such as economy, culture, politics, and social structures. Economically, the North was characterized by industrialization, commerce, and a diverse economy that included manufacturing, trade, and finance. On the other hand, the South relied heavily on agriculture, particularly cotton plantations worked by enslaved African Americans.

The Southern economy was primarily agrarian, with limited industrialization and dependence on cash crops. This economic divide led to stark differences in social structures and attitudes. The South upheld a plantation system that was based on slavery, resulting in a hierarchical society with a small class of wealthy plantation owners and a large population of enslaved people.

In contrast, the North had a more diverse population and was home to a growing middle class, with a greater emphasis on individual freedoms and wage labor. Politically, the differences between the North and the South became pronounced as issues of slavery, states' rights and economic policies came to the forefront.

The Northern states gradually shifted towards opposing slavery and supporting abolitionist movements, while the Southern states sought to protect and expand their institution of slavery. These divisions ultimately culminated in the American Civil War, as tensions reached a breaking point. The war was fought between the industrialized, anti-slavery North (Union) and the agrarian, pro-slavery South (Confederacy).
