Explain why size is the only factor that determines the stars absolute magnitude?
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.

They all do have laws for making a building earthquake proof.

What are some facts about earthquakes?
1. Most earthquakes take place in well defined zones at transform, divergent and convergent plate boundaries. 2. An earthquake epicenter is found by analysing earthquake waves at no fewer than 3 seismic stations. 3. The Richter Magnitude Scale and Moment Magnitude Scale are used to express the amount of energy released during an earthquake. 4. The elastic rebound theory is used to explain how energy is released during an earthquake. 5. Seismology is the study of earthquakes. 6. 80% of earthquakes occur within the Circum-Pacific belt, or the Pacific Ring of Fire. 7. The Indian Ocean earthquake which occurred on Dec 26, 2004 was the result of a 9.0 magnitude earthquake which occurred in the Indian Ocean, killing over 160,000 people. 8. A seismograph is an instrument that detects, records and measures the vibrations produced by an earthquake. 9. The epicenter is not where the earthquake actually began but the point on the earth's surface directly above it. The location at which the earthquake started is actually called the focus. 10. More than 150 000 earthquakes are felt every year. 11. 900 000 earthquakes are recorded every year but many are too small to be felt. 12. An earthquake generates two types of waves, Body waves and Surface waves. 13. The arrival times of the different types of Body waves allow seismologists to find the epicenter. 14. An aftershock is an earthquake that occurs after the main earthquake. 15. Sometimes the aftershock can be larger then the initial quake.

Explain the difference between magnitude and intensity of an earthquakes?
The magnitude of an earthquake is the amount of energy released at the source of the earthquake and is measured by a seismograph. Intensity is shaking strength of an earthquake at a particular location.
Can you explain how the transfer of energy as seismic waves is related to the frequency and magnitude of earthquake in a region?
They both based on the amount of energy that is released during earthquake
How high on the Richter scale does the quake have to be felt by people?
Typically, earthquakes need to be at least a magnitude of 2.5 on the Richter scale for people to feel it. The magnitude required for human detection can vary based on factors like distance to the epicenter, local geology, and the sensitivity of the person.
How would you explain an earthquake in easy English?
An earthquake tends to be described by the visible damagecriteria according to the Mercalli scale or by the amount of energy released according to the Richter or Moment Magnitude scales.
Explain why size is the only factor that determines the stars absolute magnitude?
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
Explain the main cause of earthquakes and their effects?
The primary cause of an earthquake is faults on the crust of the earth. The cracks or sudden slips of the land are known as faults or fault planes. The point of origin of the earthquake is inside the earth and is known as the hypocenter. Maximum destruction is caused at the epicenter, the surface above the hypocenter. When there are sudden movements in the various layers of the earth, crust or mantle, concentric waves are produced. These waves are known as seismic waves and are of three types; Primary Waves (P-Waves), Secondary Waves (S-Waves) and Surface Waves (L-Waves). These waves have different patterns of movement. Earthquakes usually have foreshocks and aftershocks. The main earthquake or the one with the maximum magnitude is known as the main shock. Its intensity is calculated by the magnitude of seismic waves, measured with the help of a seismograph. The measurement is taken on the Richter scale.
Explain how velocity differs from speed?
Speed is the magnitude of velocity (which has a direction as well).
Can you explain why lions are classified as animals?
There's not really an explanation.... they are classified as animals because, well, they are animals.
