TESTE DEIN WISSEN
How do you calculate Earth's mass?
Lösung anzeigen
TESTE DEIN WISSEN
F = GM/r^2 = a

F = gravtional force
G = gravtional constantly
M = mass of the earth
r = radius of the earth

TESTE DEIN WISSEN
How was the Earth formed?  (8 bullet points) 
Lösung anzeigen
TESTE DEIN WISSEN
1. 4.6 billion years ago, earth formed from a cloud of dust and gas (a solar nebula) 

2. The force of gravity caused the nebula to collapse and then spin causing formation of the sun.  

3. Smaller particles came together.  Solar winds blew away hydrogen and helium leaving behind rocky planets including Earth. 

4. Gas planets formed further from the sun due to less solar winds where gas collected.  

5. Heavy elements in the Earth bound together and sank to the centre (the solid inner core)

6. Light material created the crust and the magnetic field formed around Earth. 

7. Early years of Earth had large impact caused pieces of mantle into space creating the moon. 

8. The mantle flows under the earth, it caused mountains and volcanoes because flows cause friction and collisions.

TESTE DEIN WISSEN
A frozen ball of water and Rock. Part of the reason why Earth has water along with a group of meteorites (carbonaceous chondrites) which were 20% water inside clay minerals.

TESTE DEIN WISSEN
Why does the atmosphere not collapse under gravity? 
Lösung anzeigen
TESTE DEIN WISSEN
- it supports itself as a pressure of its own gases. 
- gas pressure exerts upward force so it pushes to keep the atmospheres boundaries and layers preserved.
- pressure decreased going up the atmosphere because heavier molecules are lower down 
- most atmosphere molecules are below 10km which is where most infrared radiation is enjoyed from the surface of the earth.

What four parts make up an animals circulatory system?
Lösung anzeigen
TESTE DEIN WISSEN
1 - blood.  It transports dissolved gases, nutrients and waste. 
2 - blood vessels - how blood flows around the body
3 - heart - pumps blood around the body
4 - valves - ensures blood pumps in one direction

TESTE DEIN WISSEN
Define gravity
Lösung anzeigen
TESTE DEIN WISSEN
The force that keeps objects, water and the atmosphere in place on Earth. Measured as meters per second squared or newton's per kg. Gravitational force is balanced by earth as an upward force to keep things from going under the Earth.

TESTE DEIN WISSEN
Define troposphere 
Lösung anzeigen
TESTE DEIN WISSEN
The lowest layer of the earth's atmosphere.  It's height alerts according to temperature. Often at 0 to 12km. It makes up 3/4 of the atmosphere.

TESTE DEIN WISSEN
What are electromagnetic waves? 
Lösung anzeigen
TESTE DEIN WISSEN
A mixture of electric and magnetic effects. They can spread out through a volume (gas, liquid or solid) or through a vaccum. Visible light wavelengths are 5 X 10^-7 m long.
