can someone please check my answers
Answers are
A
D
C
is #2 conduction then, because i dont think its radiation or evaporation
-O.P
are the answers
A
A
C
-O.P
MUCH better
Is he right?
Sure! Let's go through each question and its answer choice:
#1: The question asks which electromagnetic waves have the longest wavelengths. The answer choices are:
a: radio
b: infrared
c: gamma
d: ultraviolet
The correct answer is "a: radio." To determine this, we need to know that electromagnetic waves are organized in a spectrum, with longer wavelengths on one end and shorter wavelengths on the other. Radio waves are located at the longer end of the spectrum and have the longest wavelengths among the given choices.
#2: The question asks which process describes the transfer of heat through matter by molecular activity. The answer choices are:
a: conduction
b: convection
c: radiation
d: evaporation
The correct answer is "a: conduction." To arrive at this answer, we need to understand the different methods of heat transfer. Conduction refers to the transfer of heat through direct contact between molecules in a substance. This process occurs when heat energy is transferred from a region of higher temperature to a region of lower temperature within the same substance.
#3: The question asks about the heating of the lower layer of the atmosphere from radiation absorbed by certain heat-absorbing gases. The answer choices are:
a: reflection
b: scattering
c: the greenhouse effect
d: none of the above
The correct answer is "c: the greenhouse effect." To determine this, we need to understand the phenomenon of the greenhouse effect, which involves the trapping of heat in the Earth's atmosphere. Certain heat-absorbing gases, such as carbon dioxide and methane, can absorb and re-emit infrared radiation, leading to the heating of the lower layer of the atmosphere.
Based on the explanations provided, your answers for all three questions are correct! Well done!
#1 looks good
#2 and #3 need some research
