Two tectonic plates colliding
Mountain chains such as the Himalayans are formed due to what process?
$1000trench
What feature is formed in the deep parts of the ocean where dense oceanic plate subducts
beneath lighter continental plate
$800
Rift valleys, trenches, mountains, volcanic chains, faults,mid-ocean ridges
What are three surface features due to plate tectonics?
$600
The moon lacks an atmosphere, wind and water
The rate of erosion on the moon is less than Earth
because?
$1000
Explain where is the newest material in the Earth’s crust found?
In the mid-ocean ridges where plate tectonics constantly extrudes new lava
$400
No, the denser planets lie closer to the sun
Is this statement true-planetary density increases with increasing distances to the sun? Why or why not?

Venus and the Gas Giants
Which planets’ rotations are difficult to determine due to their atmospheres
$1000
Terrestrial, Jovian
_____________________ are planets that are of denser materials such as iron and silicates. ________________ are less dense and made of gases like the sun.
$800
The terrestrial planets are of heavier elements and smaller, the Jovians are
lighter, larger and have more moons and faster rotational periods
What are three reasons the planets are split into two
groups?
$1000
A nebula collapses, spins faster and flattens into a disk. The center of the disk heats up forming protosun and proto
planets. Protoplanets collect material (accrete), their gravity takes over and they become planetesimals. These
collide and become planets. Leftover debris became asteroids and comets.
Describe the theory of the origin of the solar system.

Describe the orbits of asteroids and Kuiper belt
objects
Both orbit near the ecliptic plane,Asteroids are closer in between mars and Jupiter while KPO are
past Neptune

Terrestrial Planets
The asteroids are most like________________ ________________ in composition and density.
$800
Most interplanetary debris was swept up during the formation of the solar system
The fact that the rate of cratering has died down over time shows that
