What are the main causes of habitat destruction? Habitat destruction is the leading cause of biodiversity loss. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Why do animals die when […]
Why is my house so full of static electricity?
Why is my house so full of static electricity? Static increases when the air gets cold and humidity drops. To stay warm in your home, you turn up the heat, further adding to a decrease in humidity and increasing static. While static can be annoying and sometimes painful, there are some simple things you can […]
How do you know if a property is intensive or extensive?
How do you know if a property is intensive or extensive? Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance’s chemical identity. Which […]
What are types of damped oscillation?
What are types of damped oscillation? The diagram shown on the right indicates three types of damped harmonic motion. Critically damped: The system returns to equilibrium as quickly as possible without oscillating. Underdamped: The system oscillates (at reduced frequency compared to the undamped case) with the amplitude gradually decreasing to zero. What is positive damping? […]
Why does black make me look thinner?
Why does black make me look thinner? This illusion could explain why we think black is more flattering than white; black shapes appear thinner than white shapes, possibly because the contours of black objects have more definition. A lighter color object will have lines, shapes, and perhaps partitions on it that are very visible to […]
What is the process of nitrification?
What is the process of nitrification? Nitrification is a microbial process by which reduced nitrogen compounds (primarily ammonia) are sequentially oxidized to nitrite and nitrate. Ammonia is present in drinking water through either naturally-occurring processes or through ammonia addition during secondary disinfection to form chloramines. What are the steps of nitrification? In general, the nitrogen […]
When galaxies are moving away from us what light color do we see?
Which one is the best example of law of conservation of mass?
Which one is the best example of law of conservation of mass? The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it […]
What are the 3 factors that sustain life on Earth?
What are the 3 factors that sustain life on Earth? What are the 3 interconnected factors that sustain life on earth? Solar energy, nutrient cycles, and gravity. What are the features that make life possible on Earth? What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful […]
