Answer:
D. water currents melting the glaciers in Antarctica
Explanation:
The hydrosphere contains all the water on earth ranging from underground water, water in the air and water running on the surface of the earth. This water exist as liquid or ice. In liquid form, it includes water in the sea, ocean, river, underground water (wells, aquifers) and water vapor. In ice form, it includes: glaciers, ice caps and icebergs. The frozen part of the hydrosphere is known as the cryosphere.
There are interactions between the hydrosphere and cryosphere such as water currents melting the glaciers in Antarctica, melting of snows and ice.
Answer:
A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other and atom become neutral.
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other and atom become neutral. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
For example
The carbon have six protons and six neutrons so its atomic mass is 12 amu and atomic number is six.
Answer:A
