altitude
[AL-tih-tood] noun
Altitude is how high something is above a particular point. Altitude is usually measured from the level of the sea.
An airplane flying at an altitude of 35,000 feet is 35,000 feet above the level of the sea.

frostbite
[FRAWST-bahyt] noun
Frostbite is an injury in which a section of skin (and sometimes the tissues below the skin) freezes. With mild frostbite, the skin turns pale or red and cold but is not permanently damaged. With severe frostbite, the area becomes numb and eventually turns black and hard as the tissue dies. Severe frostbite is a serious, permanent injury. A person is most likely to get it in very cold, windy weather.

hubris
[HYOO-bris] noun
Hubris is extreme or foolish pride or self-confidence. The word comes from ancient Greece, when it was used to describe pride so great that it made someone think they could disobey the gods. (That never worked out; in Greek mythology, hubris always leads to the person’s downfall.)

subzero
[suhb-ZEE-roh] adjective
The prefix sub- means “under, beneath, or below.” Subzero means “below zero.” So a subzero temperature is a temperature less than zero on some scale, such as the Fahrenheit or Celsius scale.
When the needle is in the blue area, the temperature is subzero (on the Celsius scale).

summit
[SUHM-it] noun or verb
As a noun, summit means “top or peak—the highest point.” The summit of a mountain is the very top.
As a verb, summit means “to reach the top of a mountain.” If Beth and Sam summit a mountain at 1 p.m., they reach the top of the mountain at 1 p.m.
The summit of this mountain has snow.
tectonic
[tek-TAHN-ik] adjective
Tectonic comes from the Greek word for “building.” It means “relating to changes in the structure of Earth’s surface.” Earth’s crust, or outermost layer, is made up of giant slabs of rock called tectonic plates. As they slowly move, mountains and volcanoes form. Their movement can also cause earthquakes.
This video shows the edges of the Earth’s tectonic plates.

Brandon was invited to go skiing with his friends. He had never skied before, yet he refused to take a lesson and headed straight to a hill for advanced skiers. And guess what? He totally wiped out. Luckily, the worst thing he did was sprain his wrist. Later, his friend Matt told Brandon, “Dude, you’ve really got to work on your hubris.”
What did Matt mean? Why would he say this?

“Whose idea was this whole refreshing walk in the woods thing? I mean, look at my beard! Let’s go inside.”
The temperature is exactly 0º Fahrenheit. When could you describe the temperature as subzero?
