1

Which of the following describes the Earth's outer core?

45% Answer Correctly

makes up most of the Earth's volume

liquid

primarily solid

solid
Solution

The Earth's core is divided into the liquid outer core (1,430 miles or 2,300 km radius) and the solid inner core (745 miles or 1,200 km radius).

2

Elements that belong to the same period in the Periodic Table of the Elements have the same number of:

50% Answer Correctly

protons

electrons

electron shells

atomic mass units
Solution

The rows of the Periodic Table are called periods and contain elements that have the same number of electron shells ordered from lower to higher atomic number. 

3

Reproductive haploids are also known as:

62% Answer Correctly

diploids

gametes

ovum

sperm
Solution

Reproductive (haploid) cells known as gametes have half as many (23) pairs of chromosomes as normal (diploid) cells. When the male gamete (sperm) combines with the female gamete (ovum) through meiosis to form a zygote, each gamete supplies half the chromosomes needed to form the normal diploid cells.

4

Elements in the Periodic Table of the Elements are ordered by which of the following?

74% Answer Correctly

atomic mass

number of electron shells

atomic number

atomic weight
Solution

The Periodic Table of the Elements categorizes elements primarily by the number of protons in their nucleus (atomic number) and secondarily by the characteristics they exhibit.

5

Which of the following is the correct order for types of radiation from longest to shortest wavelength?

60% Answer Correctly

radio waves → visible light → gamma rays

microwaves → radio waves → visible light

visible light → ultraviolet light → radio waves

infrared waves → microwaves → ultraviolet light
Solution

The electromagnetic spectrum covers all possible wavelengths and frequencies of radiation.  From lowest frequency (longest wavelength) to highest frequency (shortest wavelength) radiation: radio waves → microwaves → infrared waves → visible light → ultraviolet light → X-rays → gamma rays.
