Here are the corrections for the questions you got wrong:

2. Fusion produces less radioactivity than fission.
False (This statement is correct. Fusion produces less radioactivity than fission.)

3. Wise travelers eat only cooked vegetables in underdeveloped areas.
False (This statement is incorrect. Wise travelers should eat only raw vegetables in underdeveloped areas to avoid the risk of contaminated water used for cooking.)

4. The kilogram is the basic unit of weight in the metric system.
False (This statement is correct. The kilogram is the basic unit of mass in the metric system, not weight.)

8. Antimalarial drugs provide immunity to the disease.
False (This statement is correct. Antimalarial drugs do not provide immunity to the disease but rather help in treating and preventing malaria.)

9. Hypothermia is similar to sunstroke.
False (This statement is incorrect. Hypothermia and sunstroke are two different conditions caused by opposite temperature extremes.)

13. 50 milliliters =
0.05 liters
False (This statement is incorrect. 50 milliliters is equivalent to 0.05 liters.)

14. 0.4 kilograms =
40 grams
False (This statement is incorrect. 0.4 kilograms is equivalent to 400 grams.)

16. One process which supplies material for the upbuilding of a continent is the___ of existing mountains and dry land.
faulting
folding
False (This statement is incorrect. The correct answer is weathering, which breaks down existing mountains and dry land to supply materials for the upbuilding of a continent.)

18. Mass is the amount of __ in a substance.
matter
space
False (This statement is incorrect. Mass is the amount of matter in a substance, not space.)

19. An orbiting satellite in a constant state of___toward the earth.
spinning
False (This statement is incorrect. An orbiting satellite is in a constant state of free-fall towards the Earth.)

21. The bulk of geologic evidence indicates that the Earth’s crust has been formed by unique, rapid __ processes.
catastrophic
uniformitarian
False (This statement is incorrect. The correct answer is uniformitarian, which suggests that the Earth's crust has been formed by slow and gradual processes over long periods of time.)

22. Geologists believe that _____.
the earth is a perfect sphere
the continents were once one large land mass
False (This statement is incorrect. Geologists believe that the continents were once one large land mass called Pangaea.)

23. The mass of an astronaut in space will be _____.
the same as on earth
greater than on earth
False (This statement is incorrect. The mass of an astronaut in space will be less than on Earth due to the absence of gravity.)

25. The two sources of new materials involved in geologic processes are:
magma
False (This statement is incorrect. The correct answer is erosion products and delta, not magma.)

26. Weight is:
a force
a mass
free fall
False (This statement is incorrect. Weight is a force, not a mass or free fall.)

27. The gravitational force on a space probe between Earth and Mars is:
zero
small
False (This statement is incorrect. The gravitational force on a space probe between Earth and Mars is large, not zero.)

29. What is true concerning the erosion of the continents?
The current measured erosion rates point to relatively young continents.
False (This statement is incorrect. The correct answer is "The current measured erosion rates correspond to very slow processes.")
