Answer:
In the aftermath of the nuclear crisis in Japan, the country engaged in a massive cleanup. It cleared tons of debris, rebuilt roadways and bridges, and demolished and cleared out damaged buildings. In the future, plans should be in place for organizing citizens in cleanup efforts, making the streets safe during cleanup, and safely disposing of debris.
In addition, public transportation and airports need to function as soon as possible after such an event. Therefore, government staff should develop disaster-recovery plans for the most vital transportation systems. Local governments also need to provide short-term and longer-term housing for those who lose their homes. Designated shelters, such as schools or other community buildings, should be made ready for this purpose. Governments also need to help people get insurance payments, loans for rebuilding, and sound advice for where to locate new homes and how to strengthen them.
At the center of the Earth is the core, which has two parts. The solid, inner core of iron has a radius of about 760 miles (about 1,220 km), according to NASA. It is surrounded by a liquid, outer core composed of a nickel-iron alloy. The outer core is about 1,355 miles (2,180 km) thick.
The correct answers are:
- Formation 2 is an intrusion;
- Formation 1 in an extrusion;
- Formations 1 and 2 are igneous rocks;
The formation one on this image is an extrusion, and the reason why it is an extrusion is that it has come out on the surface. The formation two on this image is an intrusion, and the reason why it is an intrusion is that it has formed deep into the ground.
Both of the formations will produce igneous rocks. The formation one will produce extrusive igneous rocks that will have very small crystals because of the quick cooling off of the magma. The formation two will produce intrusive igneous rocks that will have larger crystals because of the slower cooling off of the magma.
Answer:
Ferrous (Fe²⁺) and magnesium cation (Mg²⁺).
Explanation:
The olivine mineral is a type of orthosilicate, which is generally yellow to yellow-green in color. It is the main component of the upper mantle of the Earth, which can be found in igneous and metamorphic rocks.
The olivine mineral exists in the form of Mg₂SiO₄, Fe₂SiO₄, or (Mg,Fe)₂SiO₄.
<u>This silicate consists of two divalent cations, ferrous (Fe²⁺) and magnesium cation (Mg²⁺).</u>
