Q:

What is a list of ductile materials?

A:

Materials that can be pulled into wires are called ductile. Many metals are ductile, including aluminium, copper, iron and tin. Ductile metals have commercial applications. For example, wires of aluminum and copper are used for carrying electric current. Gold and silver are also ductile but very expensive.

Not all metals are ductile. Some metals break on application of tensile stress and cannot be pulled into wires. Lead is an example of a soft metal that cannot be pulled into wires.

Ductility in metals decreases with an increase in temperature. The property of ductility is due to the formation of bonds in metals at the atomic and molecular levels. Most ductile metals are also malleable and can be beaten into sheets.

    What is a list of non-renewable resources?

    A:

    The term nonrenewable resource is generally used to refer to the energy-providing resources of oil, coal, natural gas and uranium. Nonrenewable resources are any resources comprised solely, or in part, from elements on the periodic table and that were created through chemical reactions that either required conditions no longer found on Earth or that took millions of years to complete, making them nonrenewable in a practical sense.

  • Q:

    Why is the hydrological cycle a closed system?

    A:

    The hydrological cycle is called a closed system because the amount of water on the Earth does not fluctuate. While water changes forms as it flows through the hydrological cycle, there is no significant input or output of water from the planet. Rain, snow and ice that rains down onto the planet eventually melt and evaporate, thereby replacing the water that precipitated from the atmosphere.
