Answer:

c

Explanation:

While standing water in the streets and sewers (option A) and poor water quality in rivers and streams (option D) may persist for some time after the flood, they are generally considered short-term changes as they can eventually be remedied through clean-up efforts and restoration programs.

Temporary displacement of organisms (option B) can also be considered a short-term change, as organisms will eventually return to their original habitats once conditions improve.

However, a permanent change in the landscape (option C) such as altered river channels, new water bodies, or changes in topography, can have lasting effects on the ecosystem and its inhabitants. These changes may alter habitat suitability, nutrient cycling, and water availability, which can impact the ecosystem for years or even decades to come.

Answer: C

Explanation:

The landscape could be flooded. Houses and buildings may be restricted.

Answer: The kinetic energy in the solid and liquid phases is the same. The kinetic energy of the substance's particles will depend on the volume of the substance. The particles have less kinetic energy in the liquid phase than they do in the gas phase. They vibrate so quickly that the particles ionize and become plasma.

The statement which is not true about Runoff is as follows:

Thus, the correct option for this question is A.

Runoff may be defined as the excessive flow of water which is caused by precipitation that can not be absorbed by the land very efficiently. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds.

Runoff can come from both natural processes, as well as, human activities. It brings chemicals and nutrients from the land that spread on the agricultural fields into lakes and streams.

A single drop of water can be easily evaporated by the sun. So, this runoff is also effectively evaporated by the sun and makes the land completely dry gradually with a time duration depending on the severity of the runoff.

Therefore, the correct option for this question is A.

Answer:

Although Dmitri Mendeleev is most often cited as the inventor of the modern periodic table, his table was just the first to gain scientific credibility. ​It wasn't the first table that organized the elements according to periodic properties.

There are about 94 elements on the periodic table that occur in nature. All of the other elements are strictly human-made. Some sources state more elements occur naturally because heavy elements may transition between elements as they undergo radioactive decay.

Technetium was the first element to be made artificially. It is the lightest element that has only radioactive isotopes (none are stable).

The International Union of Pure Applied Chemistry, IUPAC, revises the periodic table as new data becomes available. At the time of this writing, the most recent version of the periodic table was approved in December 2018.

The rows of the periodic table are called periods. An element's period number is the highest unexcited energy level for an electron of that element.

Columns of elements help to distinguish groups in the periodic table. Elements within a group share several common properties and often have the same outer electron arrangement.

Most of the elements on the periodic table are metals. The alkali metals, alkaline earths, basic metals, transition metals, lanthanides, and actinides all are groups of metals.

The present periodic table has room for 118 elements. Elements aren't discovered or created in order of atomic number. Scientists are working on creating and verifying elements 119 and 120, which will change the appearance of the table, though they were working on element 120 before element 119. Most likely, element 119 will be positioned directly below francium and element 120 directly below radium. Chemists may create much heavier elements that may be more stable because of the special properties of certain combinations of proton and neutron numbers.

Although you might expect atoms of an element to get larger as their atomic number increases, this does not always occur because the size of an atom is determined by the diameter of its electron shell. In fact, element atoms usually decrease in size as you move from left to right across a row.

The main difference between the modern periodic table and Mendeleev's periodic table is that Mendeleev's table arranged the elements in order of increasing atomic weight, while the modern table orders the elements by increasing atomic number. For the most part, the order of the elements is the same between both tables, though there are exceptions.

Answer:

High coefficient of expansion

Explanation:

It is only mercury that is in liquid form at room temperature. It works on the principle of thermal expansion, it expands when heated and contracts when cooled. The very minute change can be notable by the use of mercury in the thermometer. So this property of the thermometer makes it suitable for measuring temperatures.

Because it is easier for metals to shed their valence electrons and form cations for a stable configuration, they have comparatively few chances of acquiring electrons.

The metals usually complete their octet in each reaction. The outermost electron shell often contains more electrons in metals. Metal atoms lose electrons when they interact with other non-metals because the energy of an electron in its outermost shell is very weak.

Metals often have low ionization energy because their electrons are positive in nature. Metals lose their electrons and trade them with non-metals to achieve a stable configuration.

Answer: The motion of the Earth's plates produces changes on a planetary scale over a range of time periods from millions to billions of years.

Explanation: Earth's surface is constantly changing. Wind, water, and ice break down large rocks and move sediments on the surface. It usually takes years for weathering, erosion, and deposition to cause noticeable changes. Some events, though, change Earth's surface much more quickly.

The surface of the Earth is called the lithosphere and varies with time. The tectonic plate, erosion, wind, and water have changed the surface structure.

Tectonic plates are the plates present inside the layers of the earth that moves under high pressure and results in the formation of new lands or drifting of lands.

The flow of the wind, water, sediments, and breakdown of the glaciers have resulted in erosion., weathering, and deposition of many changes over time.

Therefore, erosion, sedimentation, and weathering have resulted in a change in the surface structure.

Answer:

There could be several possible reasons for a small gap between rails on a railway track, such as:

1. Expansion joints: Railways are designed to allow the tracks to expand and contract with changes in temperature. To accommodate this expansion, small gaps are left between the rail ends and filled with expansion joints or plates.

2. Wear and tear: Over time, the rails may experience wear and tear due to heavy loads, weather conditions, and other factors. As a result, small gaps can appear between the rails.

3. Maintenance: During maintenance activities, rail tracks may be adjusted or replaced, which could lead to small gaps between the rails.

4. Environmental factors: Environmental factors such as soil shifts, earthquakes or other natural disasters can also affect the alignment of the rails, leading to small gaps.

These are some of the possible reasons for a small gap between the rails on a railway track.

Answer:

The small gap left between the rails in a railway track is intentional and serves a specific purpose. This gap is known as the rail joint, and it allows for the expansion and contraction of the rails due to changes in temperature. When the temperature changes, the metal rails will expand or contract, and if they were joined together tightly, they could buckle or become deformed, which could be dangerous for trains passing over them. The rail joint allows the rails to move slightly and prevent damage to the track.

Additionally, the rail joint also allows for maintenance and repairs of the track. If there were no gap between the rails, it would be challenging to replace a damaged rail or perform routine maintenance, such as tightening bolts or lubricating joints. With the rail joint, maintenance personnel can easily access and work on the track.

Overall, the small gap left between the rails in a railway track is intentional and serves a crucial function in ensuring the safety and reliability of the track.
