Why don't the continents just sink into the Earth?
Because granite is the base rock of the continents. Granite is less dense then the rest of the Earth so the continents do not sink.
Because basalt is the base rock of the continents. Basalt is less dense then the rest of the Earth so the continents do not sink.
Because continents are frozen in place and can not move.
Because the continents are too heavy to sink.
Why is there a lot of SiO2 (quartz) in granite?
Si and O is less dense, so it is found at the surface of the Earth. Also, there is a lot of Si and O available.
Si and O is dense, so it is found in the Earth. It gets pushed up from below by convection currents.
It was brought here by meteorites.
Trick question, it is not found in Granite.
Which is more likely to sink into the Earth Basalt, or Granite?
Granite
Basalt
Where is most of Earth's gold found?
Towards the center of the Earth
On the surface of Earth
In Fort Knox
South Africa
Evidence suggests that most of the gold found on the surface of the Earth came from where?
Volcanoes
Mid-Ocean Rift
Asteroids hitting the Earth
Convection currents within the Earth
What is the mechanism that causes plates to move?
Convection currents in the Earth's mantle
Earthquakes
Tsunamis
The Earth spinning so fast
How would you best describe density?
How much stuff there is in a given space
How heavy something is
How much space an object takes up
The ability of an object to float
If something has a high density will it have a tendency to sink, or float?
Float
Sink
It depends on the temperature of the object.
What are two reasons why you find a lot of sand on the surface of the Earth?
Because iron is dense and plentiful forming a lot of sand
Silicon and Oxygen are low in density found in quantity on the Earth surface.
Sand is found in basalt and then erodes out onto the ocean floor
Quartz gets pushed up from the mantle and erupts out of volcanoes. It then erodes into sane.
What is the name of where plates are moving apart?
Divergent Boundary
Convergent Boundary
Transform Fault Boundary
Name a characteristic of a divergent boundary
Mid-Ocean Ridge with a Rift
Mountains
Trenches
Snow
