In the Rocky Mountain region of the United States, north-facing slopes (downhill direction is toward the north) are typically moister and heavily forested than south-facing slopes. Why

Answers

Answer:

This is because the north-facing slopes release less moisture.

Explanation:

Both the south-facing slopes and the north-facing slopes receive the same amount of sun and rain, however, the north-facing slopes are wetter and forested. This is because the north-facing slopes release less moisture into the atmosphere. This allows the soil to become more humid and the environment more conducive to plant growth, unlike the slopes facing south, which release a lot of moisture into the atmosphere and therefore make the soil drier.

About one-third of the toxic metal, mercury (Hg), is released into the air from natural sources, such as rocks, soil, volcanoes, and the ocean. The remaining two-thirds comes from ____.

Answers

Answer:

Human activities

Explanation:

Anthropogenic activities account for the major sources of pollution of the environment. Various human activities contribute in no small way to environmental degradation.

Two-thirds of toxic metal, mercury (Hg) is released into the environment by human activities.

One of the human activities that release mercury into the environment is the extraction of metals such as sodium which requires an amalgam of sodium and mercury.

Mining and fossil fuel combustion also releases mercury in large quantities. This mercury so released leads to contamination of the environment.

What interesting patterns did you notice between the various stakeholders in relation to the arguments for and against the Keystone XL Pipeline?

Answers

Hello. You did not submit the text to which this question refers, which makes it difficult for it to be answered. However, I will try to help you as best I can.

Keystone XL Pipeline was a pipeline installation project that originated in Canada but extended to the US. The installation of this pipeline was very controversial and spurred people against and in favor of the installation. It was normal that both the people who were against and those who were in favor presented opinion patterns that are opinions that are repeated in each group.

In the group in favor of installing the pipeline, we could see a pattern where people argued that this pipeline would create many jobs, improve countries' economies, and increase the flow of energy and oil in North America. In the group against installation, we could see a pattern, where people claimed that the installation of this pipeline would negatively impact nature and encourage the use of fossil fuels that would stimulate global warming.

Answers

Answer:

laterite , I hope this helps

Laterite soil is an extremely leached version of nitosols. It is widely believed that hot, humid tropical regions are where laterite, a soil and rock type rich in iron and aluminium, developed.

What type of soil is laterite?

It is widely believed that hot, humid tropical regions are where laterite, a soil and rock type rich in iron and aluminium, developed. Due to its high iron oxide concentration, nearly all laterites are rusty-red in hue. Laterite is an iron oxide-rich soil layer that forms as a wide range of rocks weather under highly oxidizing and leaching circumstances.

Tropical and subtropical locations with humid climates are where it develops. Both laterite and laterite rocks are frequently used interchangeably. Calls for the name to be dropped are a result of these and other variations in how laterite is conceptualized (such as also as a comprehensive weathering profile or weathering theory).

Horizontal variations in air pressure cause a force which makes the wind blow. These pressure variations are caused by a. warm temperatures in the stratosphere b. non-circular shape of Earth c. uneven heating of the Earth's surface d. greenhouse effect e. Earth's rotation

Answers

Answer:

The pressure gradient causes the air to move horizontally, forcing the air directly from a region of high pressure to a region of low pressure. The Coriolis force, however, deflects the direction of the flow of the air (to the right in the Northern Hemisphere) and causes the air to flow parallel to the isobars.

what are the three types of materials that affect light differently

Answers

Answer:

Explanation:

The purpose of this lesson is for the students to learn that light interacts differently with different types of materials. Students will be able to categorize materials into 3 categories based on how the light interacts with those materials: transparent (light shines through), translucent (some light shines through, and opaque (no light shines through).

Answer:

Glass, plastic, mirrors="If a material is a light colour or has a smooth surface, more light will be reflected. Shiny opaque materials, such as mirrors, reflect most of the light that strikes them. If a material is a dark colour or has a rough surface, more light will be absorbed. Opaque objects that absorb light also become warm."

Where is it located, what are its limits, what is its climate, the way of life of its inhabitants, etc.

Answers

Answer:

1. Location: America is located on the North American Continent. The United States of America is bordered by the Pacific Ocean, the Atlantic Ocean, Canada to the north, and Mexico to the south.

2. Its limits: U.S. primacy comes with opportunity costs. An alternate path might have delivered a comparable level of security at far less expense and risk. Even many who unabashedly celebrate our 20‐​year “unipolar moment” admit that their approach is costly and that it cannot last forever. They were the ones, after all, who dubbed it but a moment.

3. Climate: the U.S. has a cold semi-arid climate in the interior upper western states, to warm to the hot desert and semi-arid climates in the southwestern U.S. East, the climate is humid continental in northern areas.

4. Life of inhabitants: the United States 2020 population is estimated at 331,002,651 people at mid-year according to UN data. the United States population is equivalent to 4.25% of the total world population. the U.S.A. ranks number 3 in the list of countries (and dependencies) by population.
