Each half of the heart has an upper collecting chamber, the atrium, and a lower pumping chamber, the ventricle. You can remember their location because A comes before V. The atrium is above the ventricle. 1 How many ventricles are in the heart? 2 How do you remember the anatomy of the heart?
Read moreBy far the most active deep focus faulting zone in the world is that caused by the Pacific Plate subducting under the Australian Plate, Tonga Plate, and Kermadec Plate. Earthquakes have been recorded at depths of over 735 kilometres (457 mi), the deepest in the planet. 1 Is shallow or deep earthquake worse?
Read moreWell-preserved large craters like Tycho (about 53 miles [85 kilometers] across), Copernicus (58 miles [93km] wide), and Aristarchus (25 miles [41km] in diameter) have rim-to-floor depths of about 15,700 feet (4,800 meters), 12,500 feet (3,800m), and 9,800 (3,000m), respectively. 1 How many miles deep are the craters on the Moon? 2 How deep
Read moreHow do you know if you are driving on black ice? Because you can’t see black ice, you’ll first notice it when you feel your car start to slide or lose traction. If small shifts in your steering seem to generate an exaggerated response from your vehicle, it’s a sign that you may be driving
Read moreHow can we be confident that the models are on the right track? We can check the models by comparing their predictions for radius, surface temperature, and luminosity, as well as other observable parameters generated by studying helioseismology. 1 What is the difference between nuclear fission and nuclear fusion which one is used
Read moreDeep earthquakes under the Central Andes are concentrated in the depth range of 500-600 km. Shallow events at 63 °- 66 ° W beneath the Eastern-Cordillera and the Subandean belt document recent tectonic activity. 1 Does Andes have earthquakes? 2 What was the depth of the Valdivia earthquake? 3 What depth of earthquakes
Read moreBurrows can extend anywhere from 4 to 24 feet wide and 5 feet deep. As such, armadillo digging can potentially cause structural damage if near foundations and/or driveways. 1 How do you identify an armadillo burrow? 2 Can you fill in an armadillo burrow? 3 Can you flood an armadillo out of its
Read moreInstead of the usual 12.5% of DNA that first cousins share, the two of you share around 25% of your DNA. This is the same amount that you would share with a grandparent, a half sibling or an aunt or uncle. 1 Are first cousins closely blood related? 2 What percentage of DNA
