Astronomy
The eight planets of our solar system revolve around a celestial object. What is the name of this celestial object? (HINT: it's a star)!
The Sun
The process by which water evaporates from bodies of water and soil, then condenses in the atmosphere to form clouds, is called this
The water cycle
Earth is approximately this many billion years old based on radiometric dating of rocks and meteorites
4.6 billion years old
This is the layer of the atmosphere where life exists & is closest to the surface of Earth
Troposphere
This is the practice of using Earth's resources in a way that meets present needs without compromising the ability of future generations to meet their own needs
Sustainability
This is the name of the force that keeps planets in orbit & the Moon revolving around Earth
Gravity
These are the three main types of rocks that make up Earth's crust, formed through different processes like cooling magma, compaction of sediments, and heat & pressure
Igneous, sedimentary, & metamorphic rocks
This is the name of the supercontinent that existed about 200 million years ago and has since broken apart into the continents we see today
Pangaea
This is the process by which certain gases in the atmosphere trap heat from the Sun, keeping Earth warm enough to support life.
Greenhouse Effect
These are the types of resources that can be replenished or renewed naturally within a human lifetime, such as forests, water, and solar energy
Renewable resources
This event occurs when the Moon passes directly between the Earth & the Sun, blocking the Sun's light and casting a shadow on Earth
Solar Eclipse
This theory explains how Earth's crust is divided into plates that move and interact, causing earthquakes, volcanic activity, and mountain formation
Plate tectonics
These are the 4 major eons of Earth's history, in order from oldest to most recent
Hadean, Archean, Proterozoic, and Phanerozoic eons
This is what is created between two different air masses with different pressure & humidity
A front
This is the term for the resources that exist in limited quantities and cannot be replaced once they are used up, such as fossil fuels and minerals
Nonrenewable Resources
Name the two types of planets in our solar system... (HINT: composed of rocky material versus gases)
Terrestrial & Jovian Planets
This is the process by which weathered rock and soil particles are transported and moved from one location to another by water, wind, or ice
Erosion
This mass extinction event occurred about 66 million years ago and is believed to have been caused by an asteroid impact, wiping out the dinosaurs
Cretaceous-Paleogene extinction
This is a tropical cyclone that forms over warm ocean waters in the Atlantic and Eastern Pacific and is characterized by strong wings and heavy rainfall
Hurricane
This is the practice of collecting and processing waste materials to transform them into new products, reducing the need for raw materials and conserving resources
Recycling
This is the process at which hydrogen atoms combine to produce helium atoms & energy which is released in the form of light and heat
Nuclear Fusion
This type of feedback loop occurs when a change in Earth's system causes a response that reduces or slow down the original change, like when increased cloud cover reflects sunlight and cools the planet
Negative Feedback
During this era, which lasted from about 541 to 252 million years ago, most animal life was found in the oceans, and fish, amphibians, and reptiles first appeared
Paleozoic Era
List 1 human activity that contributes significantly to climate change by releasing greenhouse gases or reducing the planet's ability to absorb CO2
Deforestation, agriculture, industrial processes, and burning fossils fuels
This is the contamination of air, water, or soil by harmful substances that damage ecosystems and negatively affect human health and well-being
Pollution
