Life Science
What process has lead animals like giraffes to have long necks?
Evolution
What do we call a star that explodes at the end of it's life cycle?
A nova, or a supernova
Can matter be created or destroyed?
No, matter can only change forms. For example, burning a log doesn't destroy the matter in the log, it transforms it into energy in the form of heat.
Why is the sea level rising?
Ice melting and water expanding as it warms.
What phobia does a person with Hippopotomonstrosesquippedaliophobia have?
The fear of long words!
By what process have humans created dog breeds?
Artificial selection
Why do people living in the northern hemisphere experience opposite seasons to those living in the southern hemisphere?
Because the earth has a tilted axis. Since the earth is tilted, as we move around the sun, the northern hemisphere will be closer to the sun for part of the year, and the southern hemisphere will be closer to the sun for the other part.
What is temperature?
It is the average kinetic energy of the particles in a substance.
Why are we getting more storms and hurricanes?
Warmer air means increased precipitation, and hurricanes are becoming worse because they are caused by warm ocean water.
around 10 million!
What is a gene?
a piece of hereditary material that is passed from parent to offspring
What are the four(maybe five)different layers of the atmosphere?
troposphere, stratosphere, mesosphere and thermosphere, exosphere
What is newton's first law of motion?
Objects at rest stay at rest unless acted upon by an external force
What are some of the things we can do to stop climate change?(name three)
Stop using fossil fuels, invest in renewable energy like wind, solar, and hydroelectric power, increase public transportation and ban gas powered vehicles, plants trees and protect our existing forests and greenery, and more!
On average, how many horse power does a horse actually have?
Up to 24 horse power!
In plant cells, what is the role of a chloroplast?
Chloroplasts are responsible for making sugars through photosynthesis
What are the three kinds of plate tectonic boundaries?
divergent(pushing against each other), convergent(one pushing under the other), and transform(rubbing against each other, moving perpendicular)
What is the difference between an elastic and inelastic collision?
In an elastic collision, both momentum and kinetic energy are conserved. In inelastic collision, only momentum is conserved.
What was agreed upon the Paris agreement of 2015?
To keep global temperature rise well below 2℃ pre-industrial levels and to pursue a path to limit warming to 1.5℃
What is the longest time a person has been constipated?
45 days!
In an animal cell, where are most of the cell's genes stored?
In the nucleus
What do we call the different phases of the water cycle?(name at least three)
evaporation, condensation, sublimation, precipitation, transpiration, runoff, infiltration
What is work?
Work is force * displacement, so the amount of energy that is spent moving an object a distance.
How do wildfires contribute to climate change?
Releases more greenhouse gases, reduces trees and greenery that trap and convert co2 into oxygen
Are ginger cats mostly male or female?(bonus points if you know other cat breeds)
Male! Calicos are also mostly female
