Alfred Kroeber did explain the theory of environmental determinism first so that means the statement is true.
Erosion is the process of removing rock particles by water, wind, ice or gravity.
Earth's air is made up of molecules of different gases that are not joined chemically, and a terminology which best describes air is mixture.
<h3>What is a mixture?</h3>
A mixture can be defined as a combination of two (2) or more substances which are present in varied proportion (unfixed ratios). Also, a mixture can be visibly seen with our na-ked eyes and separated by physical means.
<h3>The types of mixture.</h3>
In Chemistry, there are two (2) main types of mixture and these include the following;
From the above definition of a mixture, we can reasonably infer and logically deduce that the particles of a mixture do not have a set ratio on how to combine and they can be separated through the use of a physical separation technique.

Answer:
Power per unit area released by the Earth is 459.30 Watt per meter square.
Explanation:
Stefan-Boltzmann Law is given as:
Where:
Stefan-Boltzmann constant
T = Absolute temperature of the body
The Earth has an average surface temperature of approximately,T= 300 K
Power per unit area released by the Earth :
Answer:
They have been shaped by physical weathering.
Explanation:
Physical or mechanical weather is the type of erosion responsible for breaking down rocks without chemical processes. There are many types of physical weathering that affect the landscape in many ways.
- Thermal stress makes a rock expand and contract and eventually break.
- Frost causes cracks in rocks by fracturing them during the formation and melting of water molecules.
- The Oceans weather coast lines through wave action and salt crystal weathering.
- In a process known as unloading, rocks formed underground and exposed to the surface can fracture.
- The weight and power of glacial masses erodes glacial valleys through abrasion.
