Answers

Answer 1
Answer:

Answer:

Mt. St. Helens.

Explanation:

This stratovolcano erupted in 1980 in the United States. Although there were warnings of its impending eruption, it still killed dozens, partly because it first blew sideways, producing a monstrous landslide. This volcano is Mt. St. Helens. Mount St. Helens is an active Volcano located in Washington. It is believed to have been formed 275 thousand years ago, it is an explosive dacite volcano. During the 1980 eruption of the volcano, it first blew off from the side and later the summit was removed leaving a horse-shoe shaped crater.

Which layer of the Earth is composed of iron and nickel, and has two main parts called the outer ___________ and the inner ___________ ?a. the mantle
c. the crust
b. the core
d. the lithosphere

Answers

The Crust and Lithosphere (which are almost synonymous) are not typically divided into two distinctive layers, so we can reject them.

The correct answer is is the core: (b). The inner core is solid and it's made of iron and nickel. The outer layer is liquid and this is the reason for the differentiation of the two parts. 

Final answer:

The Earth's core, which is composed of iron and nickel, is the layer referred to in the question. It's divided into an outer core, which is hot and liquid, and an inner core that's solid due to intense pressure.

Explanation:

The layer of the Earth composed of iron and nickel, with two main parts called the outer and inner sections, is the core. The core is the deepest layer of the earth and is divided into the Outer Core and the Inner Core. The Outer Core, which borders the mantle, and the Inner Core, the earth's center, are both primarily made up of iron and nickel. The outer core is fluid and hot, while the inner core is solid due to extremely high pressure. These metallic elements give the core its significant density and heat conductivity.

some people have questioned the wisdom of building large cities in desert regions. Do you agree? explain your reasoning

Answers

I do not agree because if you build a large city in the desert it will cost more that it would to build it around water.

Final answer:

Building large cities in desert regions can have advantages and disadvantages.

While harnessing renewable energy sources is a potential advantage, water scarcity and extreme temperatures are disadvantages that need to be considered.

Explanation:

Building large cities in desert regions can be both advantageous and disadvantageous. The decision to build large cities in desert regions depends on various factors such as available resources, infrastructure, and long-term sustainability. While some may argue that it is unwise due to limited water resources and extreme temperatures, others may see potential in harnessing renewable energy sources and creating oasis-like environments.

One advantage of building large cities in desert regions is the potential for harnessing renewable energy sources such as solar and wind power. Desert regions receive ample sunlight, making them ideal for solar energy production. These cities can serve as test beds for implementing innovative and sustainable technologies, thus reducing dependency on fossil fuels.

However, there are disadvantages to consider as well. Desert regions often face water scarcity, making it challenging to provide a sustainable water supply for large populations. Additionally, extreme temperatures in deserts can pose health risks and make outdoor activities difficult.

Explain why volcanoes often form on the continental plate after an ocean-continental plate collision.

Answers

Because when the tectonic plates collide, the overlapping of the continental plates lift up the oceanic plate, which therefore, forms the mountain or volcanoe.
In a nutshell:

Both the colliding tectonic plates, when an earthquake or continental drift occurs, collides against each other, and due to the equal force from both ends, the earth gets pushed upwards, to either form mountains, volcanoes or valleys.

Which of the following choices is the most abundant chemical sedimentary rock?a. breccia
b. conglomerate
c. limestone
d. quartz

Answers

c. limestone...............................

Final answer:

Out of the choices listed, limestone is the most abundant chemical sedimentary rock. These are formed by the combination of water components to create a new compound, with limestone usually created from calcium carbonate shells in certain environments. therefore, option c is correct.

Explanation:

The most abundant chemical sedimentary rock among the options provided is limestone. Sedimentary rocks are formed by the deposition and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surfaces. Chemical sedimentary rocks, like limestone, are created when water components combine to form a new compound. For example, limestone is usually formed in clear, warm, marine environments from the calcium carbonate shells of organisms.
