Conduction and convection both require some material substance
to move heat from one place to another, and there's none of that
between the sun and Earth.
The only way for thermal energy to move from place to place with
nothing in between is by the process of radiation, and that's how
it gets here from the sun.

Explanation:
Answer:
A) 
B) 
Explanation:
A) Using the Archimedes' force we can find the weight of water displaced:
Where:
: is the weight of the block in the air = 20.1 N
: is the weight of the block in the water = 15.3 N
Now, the mass of the water displaced is:
The volume of the block can be found using the mass of water displaced and the density of the water:
B) The density of the block can be found as follows:

The rocks formed from the seafloor sediments deposited in the Amadeus basin were softer than the Arkose sandstone because the Amadeus basin were made up of marine and non-marine sedimentary rocks which are softer compared to quarts which make up mostly the Arkose sandstone.
