Answer:
The Earth's magnetic field is somewhat caused by the composition of the earth's core which is rich in iron minerals. There is a solid inner core that is made of iron which makes up to 2/3 of the moon's size. The charged metal of the iron produces electric currents, consequently resulting to Earth's magnetic field.

Answer:
They use spears.
Explanation:
The hunting method that the Clovis people used for killing the large animals is the use of spears. These spears have a pointed head which easily penetrate in the body of these large animals and kill them in a very less time. They mostly hunt big animals in groups which make easier the hunting of animals. In this period when the Clovis people were present, extinction of mammoths, giant sloth and bison in North America occurs due to hunting and climate change.
Earth would basically look like the Moon; minus the craters, of course. This is because with no atmosphere to hold all of the Oxygen near the surface, all life would die off fairly quickly.
The correct answer is co-adaptation.
Co-adaptation in biology refers to the procedure by which two or more species, phenotypic traits or genes go through adaptation as a group or pair. This takes place when two or more associating features go through natural selection together in response to the similar selective pressure or when selective pressures change one feature and simultaneously changes the interactive feature. These associating features are only beneficial when together, in certain cases resulting in increased interdependence.
Eukarya is the domain containing all organisms with eukaryotic cells.
