Near-surface Earth materials (soil, rock, debris, etc.) are subject to physical and ct Jemical degradation called weathering. Weathering produces solid particles and even ions in solution-the raw materials for sediments. These solid and dissolved products are almost always moved by gravity, water, and/or wind from where they were initially created by weathering processes. Sediment deposition begins when the transport mechanisms-gravity, wind, or water currents -- slow down enough such that the sediments can settle out the Latin sedimentum means to settle').

Graded beds are characterized by a gradual change in grain size from coarse (large) to fine (small) from bottom to top. This pattern is commonly related to changes in the energy level of the water that carries, and eventually deposits, the grains. High-energy, vigorous currents can pick up and transport large, heavy sediment particles. In contrast, stagnant water has no energy and cannot keep even fine-grained sediments suspended in the water column. As a result, very fine, mud-sized grains can be deposited. If beds exhibit a gradual change in grain size, then it follows that the current velocity that deposited them must also have changed during the depositional process. In this activity, choose from statements that describe how grain size and current velocity are connected, and how that helps us understand graded beds. Read the following sentences and select which is true.

a. Graded beds imply that only fine particles can be deposited in high velocity currents, and only coarse-grained sediments can be deposited in low velocity currents.
b. All sizes of sediments can be transported and deposited in the full range of energy levels associated with different depositional environments.
c. Graded beds are evidence of a decrease in current velocity during deposition whereby coarse sediments settle out first, followed by finer sediments as the velocity decreases over time.
d. Graded beds imply that the currents that deposited them always had very high velocities.

If a country has a strong military presence and a border between two
groups of people, is this country experiencing peace or unrest?

Answers

If there is a case where a country has a strong military presence and there is also a strong border between two groups, the country is experiencing unrest.

Why is this the case?

When there is a strong military presence deployed in an area, it means that they were deployed in order to end a conflict of sorts.

In addition to this, there is a strong border between two groups of people so these people might be the source of the unrest and the border is there to stop the groups from interacting and causing unrest.

How can drought be triggered by physical conditions? ​

Answers

Answer:

Explanation: When rainfall is less than normal for a period of weeks to years, streamflows decline, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water-supply problems develop, the dry period can become a drought.

Stream flows decrease, lake and reservoir levels drop, and the depth of water in wells rises when rainfall is below average for a period of weeks to years. The dry spell could turn into a drought if the dry weather continues and problems with the water supply arise.

What causes draughts?

A drought is a time when the weather is drier than usual and there are issues with the water supply. Although the amount of precipitation at a specific region changes from year to year, on average it remains pretty stable across time.

The average annual precipitation in the Southwest's deserts is less than 3 inches. In comparison, the Northwest receives more than 150 inches of precipitation year on average. The soils might dry out and plants can die when there is little or no rain. Stream flows decrease, lake and reservoir levels drop, and the depth of water in wells rises when rainfall is below average for a period of weeks to years.

The Big Bang theory is supported by observations of distant galaxies receding from our own, of the measured composition of stars and non-stellar gases, and of the maps of spectra of the primordial radiation

Explanation:

Big Bang was an explosion that occurred 15 billion years ago, leading to the formation of galaxies of stars and other cosmic bodies.

What is Big Bang theory?

The Big Bang event is a theory that defines how the universe expanded from an initial state of high density and temperature.

It is by no doubt that our universe had had its own starting point but how it really started became a debate for the scientists over the past many centuries. From theories such as Ekpyrotic theory, White Holes, the Matrix theory, and Quantum theory, the Big Bang theory is the theory mostly accepted by the scientists. According to the theory, the universe started as a singularity, that is, from a black hole under the extreme gravitational pressure and expanded (instead of exploded) and cooled. Its cooling, according to the theory, is still happening now as of the moment.

A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water.

Answers

Answer:

Facundo is comparing the population distribution of the two states.

Explanation:

Politics; is not correct because there isn't anything political that is mentioned or attributed in what Facundo is comparing and investigating.

Productivity display; is not correct because this is an economic metric, and Facundo doesn't have his focus on that.

Geomorphology; is not correct because this a science that is part of physical geography, thus it doesn't have anything to do with the human populations.

Population distribution; is correct because Facundo is comparing the populations of these two states, their densities, the area in which they live, thus his focus is on the population distribution.

Suppose you are visiting the equator. It is noon. The Sun is at its highest point in the sky for the day, which is directly over your head. You call a friend on the phone, and she says it is also noon where she is but the Sun is not directly overhead at that location and time. It is a little lower in the sky for her. Compare the longitude and latitude where you are with the longitude and latitude where your friend is. Are they alike or different? How do you know?​

Answers

Answer:

Latitude on the equator is 0 degrees and longitude is 180 degrees

Explanation:

Both are different because you are on the equator while your friend is slightly away from the equator. The longitude of your is on the equator due to the sun location whereas  your friend is present near your location due to the same time i. e. noon but away from the equator because of the location of the sun on his head. Your latitude on the equator is 0 degrees and longitude is 180 degrees while your friend has more than 0 degrees latitude and less than 180 degrees longitude.

Based on the Sun direction during the day time, the Latitude on the equator is 0 degrees and longitude is 180 degrees

The latitude and longitude is different because you are on the equator while your friend is slightly away from the equator.

The longitude of yours is on the equator due to the sun location whereas  your friend is present near your location due to the same time i. e. noon but away from the equator because of the location of the sun on his head.

The latitude on the equator is 0 degrees and longitude is 180 degrees while your friend has more than 0 degrees latitude and less than 180 degrees longitude.

In conclusion, the Latitude on the equator is 0 degrees and longitude is 180 degrees based on the Sun direction during the day time.

Tornadoes are typically associated with a range of other weather events, such as high winds, heavy rain, and hail. They can occur in a range of different sizes and strengths, from small and weak tornadoes to large and powerful ones.

The paths of damage caused by tornadoes can vary in length, with some causing damage only a few feet wide and others causing damage that stretches for miles.
