Back

Convergent movement occurs when two tectonic plates move towards each other, often leading to one plate being forced below another, creating subduction zones.

Front

What is NOT evidence of the Big Bang?

Back

Steady state is NOT considered evidence of the Big Bang; evidence includes Red Shift and Cosmic Microwave Background Radiation.

Front

What is the correct order for the life cycle of the sun?

Back

The life cycle of the sun is: nebula, fusion stage, red giant, white dwarf, black dwarf.

Front

Where does molten material rise in seafloor spreading?

Back

Molten material rises along mid-ocean ridges during seafloor spreading.

Front

How does the distance from the sun affect a planet's orbit?

Back

The farther away a planet is from the sun, the longer it takes to orbit the sun once.

Front

What is the definition of a nebula?

Back

A nebula is a giant cloud of dust and gas in space, often the birthplace of stars.

Front

What is the significance of Red Shift in astronomy?

Back

Red Shift indicates that an object in space is moving away from us, providing evidence for the expansion of the universe.

Front

What is Cosmic Microwave Background Radiation?

Back

Cosmic Microwave Background Radiation is the afterglow radiation from the Big Bang, filling the universe and providing evidence for its early hot state.

Front

What happens during the fusion stage of a star's life cycle?

Back

During the fusion stage, a star fuses hydrogen into helium, producing energy that makes the star shine.

Front

What is a black dwarf?

Back

A black dwarf is a theoretical stellar remnant that occurs when a white dwarf has cooled and no longer emits significant heat or light.
