Spheres of the Earth
This sphere is the mostly solid, rocky part of Earth that extends from the center of the Earth to the surface of Earth
What is the Geosphere?
In this layer of the atmosphere, temperatures can reach up to 1500 degrees Celsius, but feels much colder due to the low density of particles.
What is the Thermosphere?
This is the measure of how hot or cold something is and is measured by a thermometer.
What is Temperature?
This is a large volume of air in which temperature and moisture content are nearly the same throughout.
This type of severe weather is an intense local storm that forms strong winds, heavy rain, lightning, thunder, and sometimes hail.
What is a Thunderstorm?
This sphere is the part of Earth that is liquid water.
What is the Hydrosphere?
This is the lowest layer of the atmosphere that contains almost 80% of the atmosphere's total mass.
What is the Troposphere?
This is the amount of water vapor in the air and is measured by a psychrometer.
What is (relative) Humidity?
This forms between two air masses and can come in many varieties: cold, warm, and stationary.
This form of severe weather is a tropical low-pressure system with winds blowing at speeds of 119 km/hour or more; can also be called typhoons or cyclones.
What is a Hurricane?
This sphere is all of the frozen water on Earth.
What is the Cryosphere?
These are the two main gases that make up the atmosphere.
What are Nitrogen and Oxygen?
This is any form of water that falls to Earth's surface from the clouds; comes in four forms: rain, snow, hail, and sleet; this can be measured by rain gauges or metersticks.
What is Precipitation?
This type of system produces clear weather when air sinks and moves outwards.
What is a High-Pressure System?
This form of severe weather is a destructive, rotating column of air that has very high wind speeds and that is sometimes visible as a funnel-shaped cloud.
What is a Tornado?
This sphere is mostly made of invisible gases that surround the Earth up to 600 km from the surface of Earth.
What is the Atmosphere?
This is the area of the Stratosphere, 15 to 40 km above Earth's surface, which protects the Earth from solar radiation.
What is the Ozone Layer?
This is the force of air molecules pushing down on an area and is measured by a barometer.
What is Air Pressure?
This type of system produces rainy weather as air comes together and rises.
What is a Low-Pressure System?
This can happen when a hurricane moves into a coastal area, carrying with it large amounts of ocean water.
What is a Storm Surge?
This sphere is made up of living things and the areas of Earth where they are found.
What is the Biosphere?
This is the process by which gases in the atmosphere absorb and give off infrared radiation that warms the planet.
What is the Greenhouse Effect?
This is air that moves horizontally to the ground; can measure speed by anemometers and measure direction by vanes.
What is Wind?
These can influence coastal temperatures depending on whether they are warm or cool.
What are Ocean Currents?
These are the three major climate zones on Earth that are based upon latitudes.
What are the Polar, Temperate, and Tropical regions?
