Meaning of Amplitude

Wat is the maximum displacement or distance moved by a point on a vibrating body or wave from its equilibrium (or mean) position?

100

Meaning of constructive interference

Constructive interference is a phenomenon where two or more waves combine to create a single wave with a greater amplitude.

100

The most likely moon formation theory

What is the Giant Impact Hypothesis?

100

Cosmic cloud of gas and dust

What is a nebula?

100

These massive sections of Earth’s lithosphere float on the semi-fluid asthenosphere and move slowly over time.

What are tectonic plates?

200

Meaning of Pitch

What is the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone?

200

Meaning of Destructive interference

Destructive interference is a phenomenon where two or more overlapping waves combine to produce a wave with a smaller amplitude, which can even be zero if the waves are perfectly out of phase

200

This theory proposes the Moon split off from a rapidly spinning early Earth.

What is the Fission Theory? 

200

Nebulae that are so dense that they block out the light from stars

What are dark nebulae?

200

The driving mechanism of plate tectonics is partly attributed to this process in the mantle, involving the slow circulation of hot, plastic rock

What is mantle convection?

300
Meaning of Frequency

What is the measure of how many times a repeating event, such as a wave or oscillation, occurs in one second 

300

The way Noise canceling headphones work!

What is destructive interference?

This Shakespeare play features the line, “To be, or not to be: that is the question.”

What is Hamlet?

300

These massive clouds of gas and dust are the primary sites of star formation in galaxies.

What are stellar nurseries or molecular clouds?

300

At divergent boundaries along the mid-ocean ridges, new oceanic lithosphere forms through this process, which also contributes to seafloor spreading.

What is magmatic upwelling or volcanic accretion?

400

Meaning of Peak and Trough

The peak (or crest) is the highest point of a wave, while the trough is the lowest point.

400

When a sound wave reinforce

When a sound wave reinforces another, their amplitudes add together, making the sound louder through constructive interference.

What one video did we watch(the simulation) and who made it

The one by Nasa

400

When a dying star expels its outer layers and leaves behind a hot core that illuminates the expelled gas, it creates this type of nebula.

What is a planetary nebula?

400

This type of plate boundary is characterized by two plates sliding past each other, often producing transform faults and earthquakes without significant volcanic activity.

What is a transform boundary?

500

Meaning of the "LINE OF EQUILIBRIUM"

The line of equilibrium for a sound wave represents the normal, undisturbed state of the medium—such as air—when no sound is present.

500

This phenomenon occurs when two coherent sound waves of slightly different frequencies reinforce and cancel each other periodically, producing alternating loud and soft sounds known as what?

What are beats?

500

The similarities in oxygen isotopes between Earth and its satellite provide strong evidence supporting this theory of the Moon’s origin.

What is the Giant Impact Hypothesis?

500

This nebula, visible after a supernova explosion, consists of expanding gas and dust, often forming complex filamentary structures, with the Crab Nebula as a prime example.

What is a supernova remnant?

500

When two plates move away from each other, they form this type of boundary, often creating mid-ocean ridges.

What is a divergent boundary?
