Answers
Answer:
1.An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. ... Scientists can't tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock.
2.An orbit is a regular, repeating path that one object in space takes around another one. An object in an orbit is called a satellite. A satellite can be natural, like Earth or the moon. Many planets have moons that orbit them. ... Planets, comets, asteroids and other objects in the solar
system orbit the sun.
3.Natural gas is a non-renewable hydrocarbon used as a source of energy for heating, cooking, and electricity generation. It is also used as a fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals.
4.Physical properties like density, melting point etc. Mechanical properties like hardness, strength, brittleness or ductility etc. Electrical properties like conductivity. Magnetic properties like ferro, para, and dia magnetism.
5.Take a bowl/beaker half filled with water, place a lemon in the beaker of water. ... Now, observe the immersed lemon from the top of the bowl/beaker. It is noticed that it is visible clearly from the top. Hence, this proves that water is transparent.
