Question

The most abundant metal in Earth's crust, this silver-white element is characterized by its low density, resistance to corrosion, and high strength. It is used for a variety of structural purposes, such as in airplanes, boats, and cars.

Options:
A) Iron
B) Copper
C) Aluminum
D) Zinc

Answer 1

Aluminum is the most abundant metal in Earth's crust characterized by its low density and resistance to corrosion, widely used in transportation and construction.

Step-by-step explanation:

The most abundant metal in Earth's crust that meets the description provided is aluminum. This silver-white element is indeed known for its low density, high strength, and resistance to corrosion. Aluminum is used extensively in the construction of airplanes, boats, and cars due to these properties. It is usually alloyed with other elements like silicon, copper, or magnesium to increase its strength for various structural purposes. The applications of aluminum are vast, like in the construction and transportation industries, manufacturing of aluminum cans and aluminum foil – all of which rely on the metal's lightweight, toughness, and resistance to corrosion.
