Earth’s solid-metal inner core is a key component of the planet, helping to give rise to the magnetic field that protects us from harmful space radiation, but its remoteness from the planet’s surface means that there is much we don’t know about what goes on down there.
Q. What is the inner core of the Earth made of?
Unlike the mineral-rich crust and mantle, the core is made almost entirely of metal—specifically, iron and nickel. The shorthand used for the core’s iron-nickel alloys is simply the elements’ chemical symbols—NiFe. Elements that dissolve in iron, called siderophiles, are also found in the core.

Q. What is the inner core made of quizlet?

Q. What matter is the inner core?

Q. Who named the months?
Birthdays, wedding anniversaries, and public holidays are regulated by Pope Gregory XIII’s Gregorian Calendar, which is itself a modification of Julius Caesar’s calendar introduced in 45 B.C. The names of our months are therefore derived from the Roman gods, leaders, festivals, and numbers.
Q. Who went to Mars first?
While those first several missions didn’t reach their target, NASA’s Mariner 4 finally did. The spacecraft launched on Nov. 28, 1964, and was the first to fly by Mars on July 14, 1965. It sent 21 photos of the Red Planet back to Earth.
Q. What color is Mars?
Red
Q. Is Mars Hot or cold?
Mars may look hot, but don’t let its color fool you — Mars is actually pretty cold! In orbit, Mars is about 50 million miles farther away from the Sun than Earth. That means it gets a lot less light and heat to keep it warm.
Q. Is Mars too hot for humans?
It isn’t too cold or too hot. There is enough sunlight to use solar panels. Gravity on Mars is 38% that of our Earth’s, which is believed by many to be sufficient for the human body to adapt to. It has an atmosphere (albeit a thin one) that offers protection from cosmic and the Sun’s radiation.
