Thermo-dynamics
Define Matter
Any substance that has mass and takes up space
What element of weather does a thermometer measure?
What layer of the atmosphere do we live in?
Troposphere
how many meters are 4.5km?
4500m in 4.5km
Define Thermal Energy
Energy created by the movement of particles (atoms), their movement produces heat
What tool is used to measure the direction of the wind?
Wind Vane
What layer of the atmosphere is the furthest from Earth's Surface
Exosphere
On Earth, What is the acceleration due to gravity?
9.8 m/s2
What are the three main ways heat is transferred in our universe?
Conduction, Convection and Radiation
How does warmer air behave?
When air is warmed, its particles spread out and rise up creating lower pressure systems
What forces must be balanced in order for a planet to retain an atmosphere?
The planet needs to have sufficient gravity and its surface cannot be too hot.
Where is DNA stored in Eukaryotic cells
The Nucleus
At what temperature does water freeze? (bonus points : give the temperature in each of the three major scales)
32°F
0 °C
-273K
What type of weather is associated with high pressure systems?
fair or settled weather, clear skies, dry conditions
What layer of the atmosphere do meteorites tend to burn up in?
The Mesosphere
Loose sediments become hard rock through this process
Lithification
Convert 30°C to Kelvin
°C -> K, add (+) 273
30 + 273 = 303K
How does the Sun's radiation create weather on Earth?
*depends on quality of response
The Suns radiation heats Earth's surface unevenly (due to Earth's axis and rotation.) Some parts become hotter than others, which create convection currents and pressure systems. As these systems move and interact with one another, they bring material like air and water with them. This movement of material create the conditions for weather, like humidity wind and precipitation.
What is the most common gas in our atmosphere?
Nitrogen
Arrange from largest to smallest: Proton, Electron, Neutron
Neutron, Proton, Electron
