Natural erosion can be caused by _______. A. Farming b. Wind c. Deforestation d. All of the above Please select the best answer from the choices provided A B C D.

Answers

Answer:

Wind, Movement and Water.

Except, I think theres and answer choice "Wind" only.

The wind is capable of causing natural erosion. As a result, Option (B) is the appropriate response.

What is erosion?

Earthen elements are worn away during erosion, a geological process in which they are moved by wind or water. Weathering, a related process that does not involve movement, dissolves or breaks down a rock.

Most erosion is caused by ice, wind, or flowing water (usually in the form of a glacier). Erosion occurs when the water or glacier ice is murky, the wind is dusty, or both. The brown tint shows that soil and rock fragments are being transferred from one location to another while suspended in the fluid (air or water).

The majority of the world's degraded land is caused by water and wind erosion, which makes excessive erosion one of the most serious environmental issues.

Hence, the accurate answer is option (B).

Answers

The epicenters can be calculated using the difference in arrival times of P waves and S waves.

We can reach this answer because:

A seismogram is a record of ground movements, which is used to determine the magnitude of an earthquake.Seismographs are the sensors that record these movements.This is done by recording the arrival and amplitudes of seismic waves.

When three seismograms are analyzed at the same time, it is common to evaluate the arrival time differences between P and S seismic waves to determine the epicenter of an earthquake.

QUESTION:

What marine current bathes the coasts of San Fernando and how it benefits the population?

ANSWER

Coastal resources provide much of what supports daily life: food, livelihood, economic development, clean water, and even the air we breathe. Healthy coral reefs may support fish harvests of up to 30 t/km2/year (Alcala 1981, 1988. White and Savina 1987, Alcala and Russ 1990; Christie and White 1994). Mangrove areas provide a wide range of benefits including clean water, food, medicines, and shoreline protection. These coastal habitats along with seagrass beds support the valuable multi-species fisheries in the Philippines.
