Science Knowledge Trivia Quiz For Kids

The cheetah is the fastest running land animal. It can reach speeds of up to 70 miles per hour in short bursts, allowing it to chase down its prey with incredible speed and agility. Its long, slender body and long legs contribute to its ability to run at such high speeds. The cheetah's acceleration and agility make it a formidable predator in the animal kingdom.

Onion is not a fruit because it is a vegetable. Unlike fruits, onions do not develop from the ovary of a flowering plant and contain seeds. Instead, onions are bulbs that grow underground and are used as a culinary ingredient for their savory flavor. While apples, oranges, and mangoes are all fruits that develop from the flowering plants' ovaries and contain seeds, onions are classified as vegetables due to their different botanical characteristics.

Fishes are capable of having oxygen underwater because they have gills. Gills are specialized respiratory organs that allow fishes to extract oxygen from water. As water passes over the gills, oxygen is absorbed into their bloodstream, while carbon dioxide is released. This adaptation enables fishes to efficiently extract oxygen from their aquatic environment, allowing them to survive and thrive underwater.

A gadget used to check temperature is called a thermometer. It is a device that measures temperature by using a temperature-dependent physical property, such as the expansion of a liquid or gas, or the resistance of a metal. Thermometers are commonly used in various fields such as medicine, weather forecasting, and scientific research to monitor and measure temperature accurately.

Black blood cells are not a type of blood cell. The correct answer is black blood cells.

The statement "There are 10 planets in our solar system" is wrong. In 2006, the International Astronomical Union redefined the definition of a planet, and as a result, Pluto was reclassified as a "dwarf planet." Therefore, there are currently only 8 planets recognized in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

There are four layers on Earth. These layers are the crust, mantle, outer core, and inner core. The crust is the outermost layer and is made up of solid rock. The mantle is beneath the crust and is composed of semi-solid rock. The outer core is a liquid layer made of molten iron and nickel. Finally, the inner core is the solid center of the Earth, consisting of iron and nickel.

Blue whale is not a fish because it is a mammal, not a fish. While sharks, goldfish, and catfish are all types of fish, blue whales are marine mammals that belong to the group of cetaceans. They are the largest animals on Earth and breathe air through lungs, unlike fish that have gills to extract oxygen from water.

Humans have demonstrated their superior intelligence through their ability to create complex societies, develop advanced technologies, and solve intricate problems. They possess higher cognitive abilities, such as reasoning, problem-solving, and critical thinking, which set them apart from other creatures on Earth. Their capacity for language, creativity, and innovation further supports the claim that humans are the most intelligent species.

Newton's first law, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and direction, unless acted upon by an external force. This means that objects tend to resist changes in their motion, either staying at rest or maintaining their current state of motion, unless a force is applied to them.
