Why ought swamps to be preserved?

Ecosystems with wetlands are essential. They host 40% of all species on the planet, shield us from flooding, give us food and clean water, and are essential in halting climate change.

How may marshes be preserved?

Pet waste, hazardous chemicals, fertilizers, and motor oil should all be kept away from surfaces that wash into storm drains since they can eventually reach and harm our wetlands.  When planting trees, shrubs, and flowers, stick to native species to maintain the biological balance of the nearby wetlands.

Why are weathering and erosion called external forces?

Answers

Answer:

Weathering and erosion are called external forces because they are caused by natural processes that occur outside the rock or earth material being affected. Weathering is the process by which rock is broken down into smaller pieces through exposure to the elements, such as wind, rain, and temperature changes. Erosion is how weathering materials are transported away by water, current, or ice. Both weathering and erosion are natural processes that occur on the earth's surface and are not caused by any internal forces within the rock or the world's material.

          A market center for the exchange of goods and services by people attracted from the surrounding area. Businesses compete for the central place. What is a market area/hinterland? An area surrounding a service that attracts consumers is an example of a nodal region.

Transportation is possible in all directions - there are no major rivers or roads to distort the pattern. People will always travel the minimum distance necessary to get the goods and services they want.

 

      Consumer services generally follow a regular pattern, based on the size of settlements. Business services disproportionately cluster in a handful of urban settlements.

The full moon is likely to appear to the surface of the earth at the same time The right answer is option A.

What is a full moon?

The lunar phase during which the Moon is completely illuminated from Earth's perspective is known as the full moon.

This happens when Earth is between the Sun and the Moon (when the Sun and Moon's ecliptic longitudes are 180° apart). This indicates that the near side of the moon, which faces Earth, is fully illuminated by the sun and appears as a roughly round disk. On average, there is a full moon once per month.

A synodic month, or the time between a full moon and the subsequent occurrence of the same phase, lasts on average about 29.53 days. Therefore, the full moon occurs on either the 14th or 15th day of the lunar month in those lunar calendars where each month starts on the day of the new moon.

Folded mountain ranges, such as the Himalayan mountain range, are characteristic of a convergent plate boundary.

What are Folded mountain ranges?

Folded mountains are the most common type of mountain, representing the world's largest mountain ranges. For example the Rockies, Andes, Himalayas, and Alps.

Specifically, they are formed at a continental-continental or oceanic-continental convergent boundary, where two tectonic plates come together and one plate is thrust up and over the other, resulting in the formation of mountains. In the case of the Himalayas, the Indian plate is colliding with the Eurasian plate, resulting in the uplift of the mountain range.

what type of convergent boundary is the himalayan mountains formed by

Answers

The Himalayan Mountains are a great example of a continental-continental convergent plate boundary, where two slabs of continental crust impacted, compressing and raising the acretionary wedge material to create the mountains.

A convergent plate barrier between the Indian and Eurasian plates is where the Himalayan Mountains developed. India used to be a sizable island equivalent in size to modern-day Australia. The Indian plate started to move northward toward the Asian section of the Eurasian plate about 225 million years ago. Around 50 million years ago, it slammed into the Eurasian plate, and it still exerts considerable pressure against the larger plate. The Himalayan Mountains were created by collision, but the Indian plate's continuous impact as it advances north continues to shape the mountains today. The mountains grow by about 2.4 inches (6.1 cm) every year on average.

Answers

During the winter months, the high Arctic region experiences 24 hours of darkness due to its location near the Earth's poles. On Ellesmere Island, and other Arctic locations, the inhabitants have a few different options for obtaining light during this period.

One option is to use artificial light sources such as electric lights and lamps. Generators and solar panels can be used to power these lights, allowing residents to have light throughout the day and night.

Another option is to use natural light sources such as the aurora borealis, also known as the northern lights. These beautiful lights, which can be seen in the night sky, can provide a source of light for outdoor activities.

Finally, on some places, they use skylights and reflective surfaces to bring natural light into buildings. These techniques can help to brighten up living spaces and reduce the need for artificial lights.

what is the basic reason that we have seasons on earth?

Answers

Seasons develop as a result of the tilt of the Earth's axis, which is around 23.4 degrees, and the fact that some areas of the planet receive more solar radiation than others.

Our planet orbits the Sun on a slant due to Earth's axial tilt (obliquity), which causes different parts of Earth to face the Sun in different directions at various times of the year.

The Northern Hemisphere receives more of the Sun's direct rays during the June solstice because the North Pole is inclined toward the Sun. Because of this, the Northern Hemisphere's summer months are June, July, and August.

Winter is created during the months of June, July, and August when the Southern Hemisphere is pointing away from the Sun at the same time. When the South Pole is tilted toward the Sun and the Northern Hemisphere is slanted away, the Southern Hemisphere experiences summer in the months of December, January, and February.

Tectonic activity, which refers to the movement of the Earth's lithosphere, is what causes ocean trenches. Ocean trenches in particular are a characteristic of convergent plate borders, which occur where two or more tectonic plates collide.
