1. Earthquake tremors happen when two large pieces of the Earth's surface suddenly slip. This generates waves to shake the surface of the earth or crust in the form of an earthquake. 2. The place where the earthquake starts, below the surface of the earth, is called the hypocenter. 3. The place above Hypocenters is called the epicenter. The earthquake will be the strongest at this point on the surface. 4. A device called seismograph is used to measure the size of the waves. The size of the waves is called the magnitude. 5. The powerful earthquakes in the ocean called Tsunami. A tsunami causes a chain of fast-moving waves. The waves can destroy houses and even inundate whole towns. 6. The most massive quake at any point recorded on Earth was in Valdivia, Chile. It occurred in 1960. Its magnitude was 9.5 on the Richter scale. That is one amazingly enormous quake on the earth! 7. Most of the world's quakes occur in the Pacific Ocean close to Japan in a spot called

1. The vertebrates are living beings having a backbone within them.   2. Fishes, amphibians, reptiles, birds, and mammals, including humans, are vertebrates. 3. Vertebrates are just 3% of the whole animal kingdom. The rest of the animals are invertebrates.  4. All vertebrates have some essential attributes such as a backbone, skull, developed brain, and advanced nervous system. 5. Vertebrates can either be warm-blooded or cold-blooded. Cold-blooded vertebrates find it difficult to manage body temperature normal. While the body temperature of warm-blooded animals remains constant irrespective of weather.  6. Fish are the most ancient known vertebrates. Fish step by step developed, or changed, into other land creatures. 7. Warm-blooded creatures or mammals are the most evolved vertebrates. Females feed their infant breast milk.  8. A completely submerged frog respiration takes place through the skin. While fishes have gills for underwater breathing. 9. Mammals develop
