Scientific Method & Measurement
This is the first step of the scientific method, where a scientist wants to learn more about something.
What is asking a research question?
This is what a moon phase is called when it is illuminated on the LEFT.
What is waning?
This Earth system includes all living things, such as plants, animals, and humans.
What is the biosphere?
This term describes the average weather conditions in an area over a long period of time.
What is climate?
These resources can be replaced naturally in a relatively short amount of time, such as sunlight and wind.
What are renewable resources?
This is an educated guess that can be tested through an experiment.
What is a hypothesis?
Earth is the third planet from this object.
What is the Sun?
This Earth system is made up of all the water on Earth, including oceans, rivers, lakes, and ice.
What is the hydrosphere?
When a warm air mass moves into an area, temperatures usually do this.
What is increase/get warmer?
This gas, released when fossil fuels are burned, is one of the main greenhouse gases in Earth's atmosphere.
What is carbon dioxide/CO2?
This metric unit is commonly used to measure the length of a pencil.
This movement of Earth around the Sun takes about 365 days and causes the seasons.
What is a revolution?
This was the theory proposed by Alfred Wegner to explain same fossils across the world.
What is continental drift?
This type of front forms when a cold air mass pushes under a warm air mass.
What is a cold front?
This effect occurs when greenhouse gases trap heat in Earth's atmosphere, causing Earth's average temperature to rise.
What is the greenhouse effect?
In an experiment testing how sunlight affects plant growth, the amount of sunlight is this type of variable.
What is an independent variable?
This occurs when there is are equal amounts of day/nighttime on a day.
What is an equinox?
This type of plate boundary occurs when one plate slides past another, often causing earthquakes.
What are transform boundaries?
This type of air mass forms over land and is usually dry and warm.
What is continental tropical (cT)?
As human populations grow, the demand for energy, water, food, and other natural resources generally does this, which can increase greenhouse gas emissions.
What is increase?
In an experiment, all factors that stay the same so the test is fair are called these.
What are controlled/constant variables?
During a solar eclipse, this object is between the sun and the earth.
What is the moon?
The molten layer beneath Earth's crust that helps move tectonic plates is called this.
What is the mantle?
This type of front occurs when a warm air mass overtakes a cold air mass, lifting the cold air off the ground.
What is an occluded front?
Answer: Burning coal, oil, and natural gas for energy releases greenhouse gases into the atmosphere. These fuels are known as this type of resource.
What are nonrenewable resources?
