Science - Basically Trivia Quiz

Answer: atom

The atom is the smallest unit of matter that forms a chemical element. There are three parts to an atom - protons, neutrons, and electrons.

Answer: False

The speed of light is much faster than the speed of sound in air. By comparison, light travels 186,000 miles in 1 second, while sound travels 5 miles in 1 second. At the speed of light one could circle the Earth 7.5 times in 1 second.

Answer: higher altitudes

At sea level water needs to reach 212 degrees F (100 degrees C) to begin boiling. At only 2,000 meters or 6500 feet of altitude, water's boiling point is 199 degrees F (93 degrees C).

Answer: 118

In 2016, the periodic table included118 confirmed elements, although new elements may be added in the future.. It is organized into 7 periods and 18 groups. It continues to evolve with ongoing research in chemistry and atomic theory.

The periodic table serves as a basic tool in chemistry. Dmitri Mendeleev, a Russian chemist, is often credited with creating the first periodic table.

Answer: talc

Talc, used to make talcum powder, is the softest and is rated at one on the Mohs scale. Topaz (a gemstone) is the third hardest on the same scale, while quartz, which can be found in many types of stones, is fourth, and calcite is eighth.

Answer: Yes

Yes. There are four states of matter. The other three are liquids, solids, and gases.
Plasmas conduct electricity. They are found naturally in stars, including the sun.

Answer: earthquakes

The moment magnitude scale is a modern method for measuring the size of earthquakes. It was developed in the late 20th century as an improvement to the Richter scale. It has become the standard scale used by seismologists to quantify the magnitude of earthquakes.

The Richter scale was developed by Charles Richter in 1935.

Answer: True

The two upper chambers of the human heart are called the right atrium and the left atrium. They receive blood coming into the heart. The right atrium receives deoxygenated blood, while the left atrium receives oxygenated blood.

The two lower chambers are called the right ventricle and the left ventricle. The ventricles pump blood out of the heart. The right ventricle sends deoxygenated blood to the lungs and the left ventricle pumps oxygenated blood to the rest of the body.

Answer: Mitochondria

Mitochondria generate most of the cell's energy supply. They also play roles in other processes like regulating metabolism, controlling cell growth, and initiating cell death when necessary. They are crucial for maintaining cellular health and function.

Answer: the Earth and the sun

For a planet similar to Earth orbiting a star similar to the sun, the closest distance it could be and still be potentially habitable would be around 93,000,000 miles or 0.95 astronomical units.

The habitable zone, or the "Goldilocks zone," where conditions are just right for liquid water, extends from about 0.95 to 1.37 astronomical units (AU) from the Sun.

Answer: False

Less than 3% of the Earth's water is fresh, but under 1% is accessible. The remainder is trapped under glaciers, ice caps, or is groundwater.

Answer: Antarctica

The Antarctic Desert is a cold desert. It covers an area of about 14 million square kilometers (5.4 million square miles), making it the largest desert by area.

The Antarctic Desert is characterized by its extreme cold, with temperatures that can drop as low as -76 degrees F (-60 C). Despite its icy conditions, it meets the definition of a desert due to its very low precipitation levels, receiving less than 8 inches (200 millimeters) of precipitation annually, mostly in the form of snow.

Answer: True

Heliology is a term sometimes used to describe the scientific study of the sun. It is the study of the sun's structure, its behavior, physical properties and its place in the galaxy.

Answer: fat

Approximately 60% of the brain's dry weight is fat, which makes it one of the fattiest organs in the body. This high fat content is crucial for maintaining the structural integrity and function of brain cells.

Answer: False

The skin is the largest organ in the human body. The skin is an organ because it is made up of multiple layers and performs specific functions. The liver is the second largest organ and the largest internal organ.
