Astronomy Pt 2

Front

What are sunspots?

Back

Sunspots are temporary phenomena on the photosphere of the Sun that appear as spots darker than the surrounding areas. They are caused by magnetic activity and can affect solar radiation.

Front

What absorbs heat emitted from Earth’s surface?

Back

Clouds and Greenhouse Gases (CO2) absorb heat emitted from Earth’s surface, contributing to the greenhouse effect.

Front

What is the radiative zone of the Sun?

Back

The radiative zone is a layer of the Sun where energy is transferred outward by radiation. It lies between the core and the convective zone.

Front

What are the inner planets of the solar system called?

Back

The inner planets are known as the Terrestrial Planets, which include Mercury, Venus, Earth, and Mars.

Front

What is the corona?

Back

The corona is the outer atmosphere of the Sun, extending millions of kilometers into space and visible during a total solar eclipse.

Front

What is the photosphere?

Back

The photosphere is the visible surface of the Sun, from which light is emitted, and is the layer we typically see.

Front

What is a solar flare?

Back

A solar flare is a sudden eruption of intense high-energy radiation from the Sun's surface, often associated with sunspots.

Front

What are prominences?

Back

Prominences are large, bright features extending outward from the Sun's surface, often in loop shapes, and are anchored to the Sun's surface.

Front

What are the gas giants?

Back

The gas giants are the four largest planets in the solar system: Jupiter, Saturn, Uranus, and Neptune, characterized by their thick atmospheres.

Front

What is the difference between terrestrial planets and gas giants?

Back

Terrestrial planets are rocky and solid (like Earth), while gas giants are composed mostly of gases and have no solid surface.
