C165 Integrated Physical Science Practice Questions - Set 4 - Part 1

Correct Answer: b) Ionic bond

An ionic bond is formed when a metal donates electrons to a nonmetal, resulting in a bond between oppositely charged ions.

Correct Answer: a) Newton's First Law

Newton's First Law, also called the law of inertia, states that an object will remain at rest or in motion unless acted upon by an external force.

Correct Answer: Physical weathering

Physical weathering involves the breakdown of rocks through physical processes such as freezing, thawing, and abrasion.

Correct Answer: Melting

Melting is the process where a solid turns into a liquid when heat is applied.

Correct Answer: Stratosphere

The ozone layer is found in the stratosphere, where it absorbs harmful ultraviolet radiation from the sun.

Correct Answer: Stratosphere

The ozone layer is found in the stratosphere, where it absorbs harmful ultraviolet radiation from the sun.

Correct Answer: Convection currents

Convection currents in the Earth's mantle are responsible for the movement of tectonic plates, which leads to earthquakes, volcanoes, and mountain formation.

Correct Answer: Transpiration

Transpiration is the process by which plants release water vapor into the atmosphere through their leaves.

Correct Answer: The Sun

The Sun is the primary source of energy for Earth's weather systems, driving the water cycle and atmospheric circulation.

Correct Answer: Earth's rotation

The day and night cycle on Earth is caused by the planet's rotation on its axis, which takes approximately 24 hours.

Correct Answer: Nitrogen

Nitrogen makes up about 78% of Earth's atmosphere, making it the most abundant gas.

Correct Answer: Wind

Wind is the primary driver of surface ocean currents, moving water across the planet's surface.

Correct Answer: Photosynthesis

Photosynthesis is the process by which plants convert sunlight into chemical energy, allowing them to produce their own food.

Correct Answer: Roots

The roots of the plant absorb water and nutrients from the soil, allowing the plant to grow and thrive.

Correct Answer: The Sun

The sun is the primary source of energy for Earth's ecosystems, providing light and warmth for photosynthesis and weather patterns.

Correct Answer: Mars

Mars is known as the "Red Planet" due to its reddish appearance, which comes from iron oxide (rust) on its surface.

Correct Answer: H2O

Water has the chemical formula H2O, which represents two hydrogen atoms bonded to one oxygen atom.

Correct Answer: Wind

Wind is a renewable resource because it is naturally replenished and can be harnessed to produce energy.

Correct Answer: Newton

Force is measured in newtons (N) in the SI system, where one newton is the force required to accelerate a 1 kg mass by 1 m/s².

Correct Answer: Tectonic plate collision

Mountain ranges are formed at convergent boundaries where tectonic plates collide and the Earth's crust is pushed upward.
