Earth & Space Science Regents Review

A comprehensive set of practice questions covering geology, meteorology, and astronomy for the 10th Grade NYC Earth & Space Science Regents exam.

What are the states of matter for the Earth's outer core and inner core?

The outer core is liquid iron and nickel, while the inner core is solid iron and nickel.

In plate tectonics, what is the difference between the lithosphere and the asthenosphere?

The lithosphere consists of rigid plates, while the asthenosphere is the soft layer that the plates move on.

What occurs at a divergent plate boundary?

Tectonic plates move apart from each other.

Which seismic waves are capable of traveling through both solids and liquids?

P-waves.

What type of weather is associated with high pressure and low pressure systems?

High pressure brings clear skies and sinking air, while low pressure brings storms and rising air.

How do cold fronts and warm fronts differ in the type of precipitation they produce?

Cold fronts cause short heavy storms, whereas warm fronts cause long steady rain.

What direction does wind move in relation to pressure?

Wind moves from high pressure to low pressure.

What is the function of an anemometer?

It measures wind speed.

What is the exact tilt of Earth's axis?

$$23.5^{\circ}$$

What are the two primary reasons for the seasons on Earth?

The axial tilt and the Earth's position in its orbit, not the distance from the Sun.

What is the difference between waxing and waning moon phases?

Waxing means the Moon is getting brighter, while waning means it is getting darker.

When do spring tides and neap tides occur?

Spring tides happen during full and new moons; neap tides happen during quarter moons.

What process powers stars and what elements are involved?

Nuclear fusion converts hydrogen into helium.

What does Kepler's 2nd Law state regarding planetary motion?

Planets move faster when they are closer to the Sun.

In the Electromagnetic Spectrum, which waves have the longest and shortest wavelengths?

Radio waves have the longest wavelengths, and Gamma rays have the shortest wavelengths.

What is the relationship between energy and wavelength in the electromagnetic spectrum?

Energy increases as wavelength decreases.

What is the difference between an asteroid and a comet?

Asteroids are rocky objects mostly between Mars and Jupiter, while comets contain ice and dust.

How do sedimentary rocks form?

They form from compaction and cementation.

Which layer of the atmosphere is known as the weather layer?

The troposphere.

What is the formula for Density?

$$Density = \frac{Mass}{Volume}$$

What are the six layers of the Sun starting from the center?

Core, Radiative Zone, Convective Zone, Photosphere, Chromosphere, and Corona.

What happens to the temperature and pressure as depth increases inside the Earth?

Both temperature and pressure increase deeper inside the Earth.
