In which type of compound are electrons shared between atoms?

56% Answer Correctly

	covalent
	molecular
	ionic
	chemical

Solution

A compound is a substance containing two or more different chemical elements bound together by a chemical bond. In covalent compounds, electrons are shared between atoms. In ionic compounds, one atom borrows an electron from another atom resulting in two ions (electrically charged atoms) of opposite polarities that then become bonded electrostatically.

As part of the carbon cycle, plants release carbon into the atmosphere through which process?

45% Answer Correctly

	evaporation
	sedimentation
	decomposition
	photosynthesis

Solution

The carbon cycle represents the ciruit of carbon through Earth's ecosystem. Carbon dioxide (CO₂) in the atmosphere is absorbed by plants through photosynthesis. Plants then die and release carbon back into the atmosphere during decomposition or are eaten by animals who breathe (respiration) the carbon into the atmosphere they exhale and produce waste which also releases carbon as it decays.

As part of digestion, the liver produces bile which breaks down:

64% Answer Correctly

	starches
	sugars
	protein
	fat

Solution

The liver produces bile which emulsifies (separates) fat.

Which of these layers is found directly below the Earth's crust?

71% Answer Correctly

	mantle
	inner core
	continents
	outer core

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.
