Ceres
Inge Lehmann discovered that this region was actually split into two distinct parts. The presence of this region causes the P-wave shadow zone observed after an earthquake. This region’s upper boundary is named for Gutenberg. The liquid part of this region is responsible for Earth’s magnetic field. For the point, name this region of the Earth made up of iron and nickel, beneath the mantle, that has “______” and _______ parts.
Inner core, outer core
___ _______ are thick masses of ice and snow that covers a vast area of land.
Ice caps
Although the five-cent coin is called the ______, the coin is only made out of 25% _______, with the rest consisting of copper

“Inge Lehmann suggested that this region has a solid component. Convection occurring in one portion of this region is the proposed mechanism for dynamo theory. This region can be divided into its ______ molten component and ______ solid component. For the point, name this region that sits directly below the mantle in the center of the Earth.
Earth’s core, Inner core, Outer core
“________ is a technique used to fuse metals together using high heat. It has many applications in industrial construction, such as bridge-building, military technology, and steel-working.”
Welding
“Gypsum can form “flowers” and “beards” in these places. “Soda straw” is a very common speleothem in these places. These places can form from the dissolution of limestone in karst topography. Mammoth and Carlsbad are two U.S. examples of these places. For the point, name these underground locations that contain Stalgmites and Stalacites which are explored by spelunkers.”

This largely spherical body’s highest point is the cryo-volcano Ahuna Mons. Along with Uranus, this body’s orbit was predicted by the discredited Titius-Bode Law. Vesta and this body were the destinations of the Dawn probe, and this body is the only dwarf planet within Neptune’s orbit. For the point, name this largest object in the asteroid belt.

Even so, pure native _________ is found in Earth’s crust only in tiny amounts, usually in ultramafic rocks,[5][6] and in the interiors of larger _______–iron meteorites that were not exposed to oxygen when outside Earth’s atmosphere. _______ was first isolated and classified as an element in 1751 by Axel Fredrik Cronstedt, who initially mistook the ore for a copper mineral, in the cobalt mines of Los, Hälsingland, Sweden. Ni is ferromagnetic at about room temperature. Alnico permanent magnets based partly on ________ are of intermediate strength between iron-based permanent magnets and rare-earth magnets.
