Answer: A. Earth and the Moon share many compositional characteristics
Explanation:
According to the giant impact theory, the Moon formed when an object of the size of Mars and geologically similar to Earth (which was called Theia by scientifics) crashed into the primitive Earth. With this collision, vaporized pieces of the crust of the young Earth were thrown into space. After this, the expelled particles were united by the action of gravity, creating the Moon.
This theory could explain in a certain way the reason why the Moon is predominantly composed of elements similar to those found on Earth, but lighter, making it less dense than Earth, since the material that formed it came from the crust, leaving the rocky core of the planet intact. This was verified by the samples of rocks brought from the Apollo missions, which indicate that it is composed mostly of the same components of the Earth.
Answer and Explanation:
In the face of a tropical cyclone, many precautionary measures can be taken in the future to prevent major and more destructive damage from happening and to allow people to be as safe as possible. Among these precautionary measures we can mention:
The evacuation of the inhabitants of a potentially flooded region, either by storm, or by rising tides.
Creation of safe and strong shelters, with availability of food and medicine.
Keep the shelter windowless, or keep the windows protected, preventing them from breaking and hurting people.
Disconnect electronic devices, but keep a communication source that informs you when the region is safe again.
Seismometers are tools which measure motion in the ground including seismic waves generated by earthquakes, volcanoes, and other activities which might create seismic waves. Seismometers measure any movement of seismic activity in the earth and today this is done by electronic means whereby the machine measures any changes in seismic activity in the surrounding areas of the seismometer. The first seismometer is believed to have been invented by Zhang Heng of China's Han Dynasty in 132 AD.
