HS. Space Systems HS-ESS1-1 Vocabulary

What is the vocabulary word for the following definition? A simplified representation used to explain complex systems or processes, such as the Sun’s life span and energy production through nuclear fusion, based on observational evidence.

• Model

• Theory

• Hypothesis

• Law

What is the vocabulary word for the following definition? The entire duration of the Sun’s existence, from its formation about 4.6 billion years ago to its eventual transition into a red giant and then a white dwarf.

• Lifespan of the Sun

• Solar Flare

• Sunspot Cycle

• Solar Wind

What is the vocabulary word for the following definition? The process in the Sun’s core where hydrogen nuclei combine to form helium, releasing vast amounts of energy that powers the Sun and radiates outward.

• Nuclear Fusion

• Photosynthesis

• Nuclear Fission

• Combustion

What is the vocabulary word for the following definition? The central region of the Sun where temperatures and pressures are high enough to sustain nuclear fusion, producing the energy that fuels the Sun’s light and heat.

• Sun’s Core

• Photosphere

• Corona

• Chromosphere

What is the vocabulary word for the following definition? Processes that move energy from the Sun’s core to its surface and beyond, including radiation, convection, and conduction, eventually delivering energy to Earth as sunlight.

• Energy Transfer Mechanisms

• Photosynthesis

• Solar Flares

• Nuclear Fusion

What is the vocabulary word for the following definition? The emission of energy as electromagnetic waves, including visible light, which travels from the Sun’s surface through space to reach Earth, providing the energy needed for life.

• Radiation

• Conduction

• Convection

• Reflection

What is the vocabulary word for the following definition? The amount of matter in stars, which influences their life cycles and energy outputs, serving as comparative evidence for understanding the Sun’s life span.

• Masses of Stars

• Luminosity of Stars

• Temperature of Stars

• Composition of Stars

What is the vocabulary word for the following definition? The stages stars go through from birth to death, which vary based on mass and composition, offering insights into the life cycle of the Sun.

• Lifetime of Stars

• Solar Flare

• Black Hole Formation

• Planetary Nebula

What is the vocabulary word for the following definition? Sudden, intense bursts of radiation from the Sun’s surface, caused by magnetic activity, which can impact space weather and communications on Earth.

• Solar Flares

• Sunspots

• Auroras

• Coronal Mass Ejections

What is the vocabulary word for the following definition? The environmental conditions in space influenced by the Sun’s activity, including solar flares and radiation, which can affect satellites, power grids, and astronaut safety.

• Space Weather

• Greenhouse Effect

• Ozone Layer

• Tidal Forces
