Second 9 Weeks Review

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust as magma rises to the surface.

Front

Describe the weather conditions at location X on Day 1 and Day 2 if Day 1 is cold and rainy and Day 2 is clear and sunny.

Back

On Day 1, the weather is cold and rainy, while on Day 2, it is clear and sunny.

Front

How does star E compare to star B in terms of temperature and brightness?

Back

Star E is cooler and dimmer than star B.

Front

What is luminosity in the context of stars?

Back

Luminosity is the total amount of energy emitted by a star per unit of time, often measured in watts.

Front

Which star has the highest luminosity among the following: Star Y, Star X, Star Z?

Back

Star Z has the highest luminosity.

Front

Which star is brighter than the sun?

Back

Aldebaran is brighter than the sun.

Front

What is the significance of a star's temperature in determining its color?

Back

A star's temperature affects its color; hotter stars appear blue or white, while cooler stars appear red or orange.

Front

What is the relationship between a star's brightness and its distance from Earth?

Back

A star's brightness decreases with distance; a star that is farther away will appear dimmer than a closer star of the same luminosity.

Front

Define the term 'star classification'.

Back

Star classification is the categorization of stars based on their spectral characteristics, temperature, and luminosity.

Front

What are the main types of plate boundaries?

Back

The main types of plate boundaries are divergent, convergent, and transform boundaries.
