Antacids may be used: 1  To reduce the symptoms of acid reflux which may cause heartburn or inflammation of the gullet (oesophagitis) . 2  These conditions are sometimes called gastro-oesophageal reflux disease (GORD). 3  To relieve some of the symptoms caused by ulcers in the stomach and part of the gut called the duodenum.
Earthâs magnetic field is generated by an interaction between rotation in the planetâs core and electrical currents.The field then creates the magnetosphere, which acts sort of like a force field, protecting the planet from the brunt of the sun's solar wind.arthâs magnetic field is generated by an interaction between rotation in the planetâs core and electrical currents.
That's as hot as the surface of the sun. The difference in temperature matters, because this explains how the Earth generates its magnetic field. The Earth has a solid inner core surrounded by a liquid outer core, which, in turn, has the solid, but flowing, mantle above it. There needs to be a 2,700-degree F (1,500 C) difference between the inner core and the mantle to spur thermal movements that â along with Earth's spin â create the magnetic field.
