I think radiation and energy transfer!
Answer: Mechanical weathering breaks rocks into smaller pieces without changing their composition.
Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.
Answer:
3°F, 0°F, -11°F, -16°F, -20°F
Explanation:
The Fahrenheit scale is a temperature scale proposed in 1724 by the physicist Daniel Fahrenheit.
In this scale:
- The freezing point of water is set at 32 degrees
- The boiling point of water is set at 212 degrees
One degree in the Fahrenheit scale is indicated with the symbol 
.
The equivalence between temperature in Celsius degrees and Fahrenheit degrees is as follows:
to convert from Fahrenheit to Celsius
to convert from Celsius to Fahrenheit
The Fahrenheit scale is an increasing monotonic scale, it means that temperature goes from negative values towards positive values without interruption. Therefore, the temperatures listed from warmest to coldest are:
3°F, 0°F, -11°F, -16°F, -20°F
primarily ionic include = sodium iodide( NaI) , calcium chloride ( CaCl2)
primarily covalent include - Ammonia (NH3) , Methane ( CH4) and
Glucose (C6H12O6)
Explanation
ionic bond is formed when there is complete transfer of electron between atoms. It occur between metal which donate electrons and a non metal which accept electrons.
for example in formation of CaCl2, ca donate 2 electron to 2 Cl atom, while 2 Cl atom accept the 2 electrons to form ionic bond.
Covalent bond is formed when two or more non metal form bond by sharing electrons pairs.
For example in NH3 3 pairs of electron are shared. to form covalent bond.
Am not exactly sure but i think ots conduction
