Midterm Review Part 1

Front

What is eccentricity in the context of orbits?

Back

Eccentricity is a measure of how much an orbit deviates from being circular. It ranges from 0 (perfectly circular) to 1 (parabolic). Higher eccentricity indicates a more elongated orbit.

Front

What effect does increasing the distance between a planet and the Sun have on the orbit's eccentricity?

Back

Increasing the distance between a planet and the Sun generally leads to a greater eccentricity, making the orbit more elongated.

Front

What is the stratosphere?

Back

The stratosphere is a layer of Earth's atmosphere located between the troposphere and mesosphere, approximately 10 to 50 kilometers above the Earth's surface, where the ozone layer is found.

Front

What is the significance of the Habitable Zone?

Back

The Habitable Zone is the region around a star where conditions may be suitable for life as we know it, typically defined by the distance from the star and its surface temperature.

Front

Which planet in our solar system is closest to the Sun?

Back

Mercury is the closest planet to the Sun.

Front

What are the relative diameters of Uranus and Neptune?

Back

Uranus and Neptune are often compared due to their similar sizes, both being classified as ice giants.

Front

What is the purpose of a map in geography?

Back

A map is a visual representation of an area that shows physical features, political boundaries, and other important information.

Front

What is the significance of the coordinates 46.5° S 72° W?

Back

These coordinates pinpoint the location of the Patagonia Marble Caves in South America.

Front

What is the difference between the troposphere and the stratosphere?

Back

The troposphere is the lowest layer of the atmosphere where weather occurs, while the stratosphere is above it and contains the ozone layer.

Front

What is the role of ozone in the stratosphere?

Back

Ozone in the stratosphere absorbs harmful ultraviolet (UV) radiation from the Sun, protecting living organisms on Earth.
