Which of these is a type of Earth's crust?

56% Answer Correctly

oceanic

metamorphic

terrestrial

sedimentary
Solution

The crust is the Earth's outermost layer and is divided into oceanic and continental types. Oceanic crust is 3 miles (5 km) to 6 miles (10 km) thick and is composed primarily of denser rock. Continental crust is 20 to 30 miles (30 to 50 km) thick and composed primarily of less dense rock. The crust makes up approximately one percent of the Earth's total volume.

2

Which of the following indicates the correct reproductive sequence?

64% Answer Correctly

zygote → ovum → fetus

ovum → fetus → zygote

none of these are correct

ovum → zygote → fetus
Solution

During intercourse, the penis ejaculates sperm, produced in the testes, into the vagina. Some of the sperm makes their way to the uterus where, if they encounter an egg to fertilize, unite with the ovum to form a fertilized egg or zygote. The zygote then may implant in the uterus and eventually develop into a fetus.

45% Answer Correctly

secondary consumers or scavengers

primary or secondary consumers
Solution

Secondary or tertiary consumers may be omnivores.

4

In the classification of life, which of the following is not a domain?

58% Answer Correctly

archaea

bacteria

animalia

eukaryota
Solution

The broadest classification of life splits all organisms into three groups called domains. The three domains of life are bacteria, archaea and eukaryota.

5

Materials like metals that transfer heat efficiently are called:

82% Answer Correctly

conductors

refractors

insulators

reflectors
Solution

Heat is always transferred from warmer to cooler environments and conduction is the simplest way this transfer can occur. It is accomplished through direct contact between materials and materials like metals that transfer heat efficiently are called conductors while those that conduct heat poorly, such as plastic, are called insulators.
