common metric units
This metric unit is commonly used to measure the mass of an object in a chemistry lab.
gram
Convert 5 meters to centimeters.
What is 500 centimeters (500 cm
This is the thin, solid outermost layer of Earth where we live.
crust
This organelle is known as the "control center" of the cell because it contains DNA and directs all cell activities.
nucleus
This geological process breaks rocks into smaller pieces without moving them.
weathering
This metric unit is used to measure the volume of a liquid.
liter
Convert 2.5 liters to milliliters.
2,500 milliliters (2,500 mL)
This is the thickest layer of Earth and is made of hot, slowly moving rock
mantle
This organelle is often called the "powerhouse of the cell" because it produces ATP (energy) through cellular respiration.
mitochondrion (mitochondria)
This process moves rock and sediment from one place to another by water, wind, ice, or gravity
erosion
This metric unit measures the length of an object.
meter
Convert 4,500 milligrams to grams.
4.5 grams (4.5 g)
This layer is made mostly of liquid iron and nickel and is responsible for generating Earth's magnetic field.
outer core
This organelle is found in plant cells and uses sunlight, water, and carbon dioxide to make glucose through photosynthesis.
chloroplast
his theory explains that Earth's crust is divided into large moving plates that cause earthquakes, volcanoes, and mountain formation.
plate tectonics
This metric unit is used to measure temperature in most science laboratories around the world.
degrees Celsius (°C)
A student measures 750 centimeters. How many meters is this?
7.5 meters (7.5 m)?
This is the hottest and most dense layer of Earth, made primarily of solid iron and nickel.
inner core
A scientist discovers a cell that contains a cell wall, chloroplasts, a large central vacuole, mitochondria, and a nucleus. Is this a plant cell or an animal cell?
Plant cell
Name Earth's four main layers from the outside to the center
crust, mantle, outer core, and inner core?
Name the four most commonly used metric units in chemistry and what each measures.
What are grams (mass), liters (volume), meters (length), and degrees Celsius (temperature)?
A chemistry lab needs 3 kilograms of a substance. How many grams is this?
3,000 grams (3,000 g)
Starting from Earth's surface, name the four main layers of Earth in the correct order.
What are the crust, mantle, outer core, and inner core
Which organelle produces ATP?
Mitochondrion (mitochondria)
This is Earth's thin, rocky outer layer where humans and most living organisms live.
