10 Questions
What is weight and how is it related to flying machines?
Weight is a force that pulls the plane down towards the ground. It is related to flying machines as they need to generate enough lift to overcome the force of weight and become airborne.
Explain the impact of flying machines on the environment at a local level.
The impact of flying machines at a local level includes air pollution, noise pollution, and habitat disruption due to the space requirements of airports.
What is biodiversity and how is it related to agriculture?
Biodiversity means that there are many types of living things. It is related to agriculture as it involves growing diverse plants, fungi, and raising farm animals to maintain a healthy ecosystem.
Name two types of flying living things mentioned in the text and their flying characteristics.
Birds: powerful flyers with wings that give them lots of lift. Insects: fast flyers with small wings that beat very fast.
What is taxonomy and what are the levels of groups in taxonomy?
Taxonomy is the study of grouping living things together. The levels of groups in taxonomy are Kingdom, Phylum, Class, Order, Family, Genus, and Species.
What is density?
Density is a measure of how many molecules there are in the air, the more 'dense' the air is.
How does temperature affect air density?
When the air gets hot, the molecules in the air move fast and spread out, leading to a decrease in density.
What is humidity?
Humidity is a measure of how much water vapor there is in the air.
What is lift?
Lift is a rising force that allows planes to go upwards.
What is viscosity?
Viscosity is a measure of how thick a liquid or gas is.
