Answer:
The arguments that could be used to challenge the idea of using wind power to provide electricity to the whole country is that there is a difficulty in capturing wind, wind power causes visual and sound impacts, as well as an impact on fauna.
Explanation:
Wind energy is a widely used method for obtaining power through wind power, which drives windmill and windmill-like mechanisms connected to a generator that produces electricity.
The main advantage of wind energy is that it is considered a clean energy, that is, obtained from renewable sources and without generating any kind of polluting waste during its production and consumption.
Although wind energy is one of the best options for obtaining energy from renewable and clean sources, it is possible to see some negative points of this technique. These negative points are:
A. Seawater is expanding as it gets warmer,
B. The ocean's conveyor belt is speeding up,
C. Upwellings are becoming more frequent.
D. The moon's gravitational pull is decreasing.
Answer:
a
Explanation:
global warming causing the icebergs to melt which rises water
The average height of Earth's oceans is increasing mainly due to thermal expansion caused by global warming. The warmer the seawater gets, the more it expands, raising the ocean levels.
The studies show that the average height of all Earth's oceans is indeed increasing over time. Amongst the provided options, a possible cause for this is, A. Seawater is expanding as it gets warmer. This concept is referred to as thermal expansion. When water gets warmer, the molecules have more energy and therefore tend to take up more space. This causes the volume of the ocean to increase, leading to a rise in sea levels. The remaining options - Ocean's conveyor belt speeding up, upwellings becoming more frequent and the moon's gravitational pull decreasing - have minimal or no direct impact on the overall rise in ocean levels.

The aluminum horseshoe bend but does not break due to the property of malleability when a blacksmith pounds it into shape with a hammer.
Malleability can be described as a property that makes a metal be changed into thin sheets when being hammered or rolled out without breaking.
This property is held by some metals that can be converted into thin sheets. It includes giving physical forces to metal to make changes in its outside shape. Some metals such as Gold, Silver, Lead, Iron, Aluminum, and Copper, are malleable.
When aluminum metal is being hammered, then at the molecular level, the Al atoms are flexible enough and slide upon each other to obtain a new shape. The bonds between aluminum atoms do not break when hammered.
Therefore, the aluminum horseshoe bend but does not break when a blacksmith hammers it into shape as the aluminum metal is malleable.
