Explanation:The tetrahedral shape is formed by the electrons repulsing one another, which forms the tetrahedron—the shape in which all the electrons are as far away from one another as possible.
Examples include methane (CH4) and ammonium(NH4+).
Methane has a central carbon atom ringed by four hydrogens, which form the "spokes" of the tetrahedral molecule.
Tetrahedral molecules are nonpolar if the four surrounding atoms are the same, in the cases of methane and ammonium, and have a bond angle of 109.5˚.
However, tetrahedral molecules can also be polar if they are like chloroform (CHCl3). The central atom has four electron domains, but they are differently sized.

The other guy on this question was incorrect, i failed that question so here is the anwser.
Hello!
Jet streams are large currents of air that travel around the planet. The ocean does not control the wind. The Sun does not control the wind. Hurricanes do not either. Mountain breezes can influence and are influenced by the jet stream.
I hope this helps!
