What percentage of our planet's surface is covered by water? (Roughly)
About 71%
(Though only 20 percent is visible to us)

Earth's land masses are presently divided into how many continents?
Can you name them all?
7
North America, South America, Africa, Europe, Asia, Antarctica, Australia
About 300 million years ago, Earth didn't have seven continents, but instead one massive supercontinent called Pangaea, which was surrounded by a single ocean called Panthalassa.

These types of forests are Earth’s oldest living ecosystems.
Rainforests are Earth’s oldest living ecosystems, with some surviving in their present form for at least 70 million years

Which element makes up most of the Earth's atmosphere?
Nitrogen.
While oxygen is necessary for most life on Earth, the majority of Earth’s atmosphere is not oxygen. Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases.
100
Most volcanoes are found along a belt, called the Ring of Fire that encircles which ocean?
The Pacific Ocean.
The Ring of Fire is the result of plate tectonics where the heavier plate in the Pacific is shoved under the other surrounding plates, creating this lengthy belt of volcanoes. Over sixty percent of all active volcanoes occur at the boundaries between tectonic plates.

True or False:
The ocean provides 30% of the oxygen we breathe.
False!
Scientists estimate that 50-80% of the oxygen production on Earth comes from marine photosynthesis.

Earth is the only planet in the Solar System with plate tectonics. How many major tectonic plates make up the Earth's outer shell?
The outer crust of the Earth is broken up into seven major tectonic plates and several minor ones. These are floating on top of the magma interior of the Earth and can move against one another.

This layer of the rainforest's structure is a dense network of leaves and branches, forming a roof over the two remaining layers.
The canopy layer.
Most rainforests are structured in four layers: emergent, canopy, understory, and forest floor. Each layer has unique characteristics based on differing levels of water, sunlight, and air circulation. While each layer is distinct, they exist in an interdependent system: processes and species in one layer influence those in another.
200
How many major layers is the Earth's atmosphere?
Earth's atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
200
Volcanic gases like sulfur dioxide can cause global _______, while volcanic carbon dioxide, a greenhouse gas, has the potential to promote global _______.
Cooling, Warming.

The mysterious Bermuda Triangle, also known as the Devil's Triangle, is said to have swallowed many ships, planes, and helicopters into its depths. In which ocean is this regional anomaly located?
The Atlantic Ocean is the youngest of the five oceans, having formed during the Jurassic Period approximately 150 million years ago following the breakup of the supercontinent Pangaea.

Name the 3 main types of rocks depending upon how they were formed in the different layers of the Earth.
Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure underground.

In Western modern medicine, what percentage of drugs come from rainforests?
A quarter of ingredients in modern medicines come from rainforest plants. A four-square-mile patch can contain as many as 1,500 flowering plants, 750 species of trees, 400 species of birds and 150 species of butterflies.
300
Which of the major five layers is the coldest:
-Troposphere
-Stratosphere
-Mesosphere
-Thermosphere
-Exosphere
The third layer, the mesosphere, has the coldest temperatures: the top of the mesosphere has temperatures as low as -148 F.

Volcano shapes can get identified by nature of eruption and kind of lava they release. How many main shape types are there?
There are four types of volcanoes based on the nature of their eruption and the kind of lava they release – cinder cone, composite, shield, and lava dome volcanoes.

Sometimes called "rainforests of the sea," what is the name for the type of underwater ecosystem that occupies less than 0.1% of the world's ocean area but provides a home for more than 25% of marine species?
Coral reefs.
A common misconception is that corals are plants or rocks but, in actual fact, they are animals. There are hard and soft varieties of coral which live together in large groups called colonies.

Fill in the blank:
Scientists think that Earth's _______ field is generated where heat creates convection motions of conducting materials to generate electric currents.
Earth’s molten iron core creates a magnetic field that extends thousands of kilometers out from the surface of the Earth forming a region called the “magnetosphere“.
400
Which rainforest Basin stores one-fifth of the world’s freshwater?
The Amazon Basin.
Rainforests get at least 98in of rain a year and sometimes almost double that at 196in. Rainforests also help maintain the world’s water cycle. More than 50% of precipitation striking a rainforest is returned to the atmosphere by evapotranspiration, helping regulate healthy rainfall around the planet.

Which of the major five layers can you find most of our clouds:
-Troposphere
-Stratosphere
-Mesosphere
-Thermosphere
-Exosphere
The Troposphere
Most of the water vapor in the atmosphere, along with dust and ash particles, are found in the troposphere—explaining why most of Earth’s clouds are located in this layer.

What is the role of seismic data on the prediction of volcanic eruptions?
A. Track magma’s movements in the volcanoes
B. Measure the forms of gas released by the volcanoes
C. Track the amount of gas emission
A. Track magma’s movements in the volcanoes
Seismic signals can trace how quickly magma is ascending, which can be used to forecast a last-minute magma population boom that could lead to a catastrophic blast.
That being said, there is no guaranteed way to predict when an eruption will occur.
500
The ocean is home to approximately what percentage of species on Earth?
Around 94%
Scientists estimate that about one million species of animals live in the ocean.

If you could separate the Earth out into piles of material, which metal ore would be the biggest pile of material at 32.1%?
Iron.
Of course, most of this iron is actually located at the core of the Earth.

Fill in the blank:
Tropical rainforests cover less than ___% of the planet, yet they are home to more than half our planet’s terrestrial animal species.
3%
Endangered species such as Bengal tigers, mountain gorillas, orangutans, jaguars, and blue poison dart frogs are just a few of the magnificent animals found in rainforests.
500
Earth’s atmosphere stretches from the surface of the planet up to as far as how many miles above? (Roughly)
6,214 miles.
The atmosphere protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn't exist on our planet's surface. And it warms our planet and keeps temperatures habitable for our living Earth.

Where does the term “volcano” come from?
It was after the epic and devastating eruption that hit Pompeii that “volcano” came into existence, naming the Earth-shattering event after an island near Sicily, named Vulcano.
The ancient Romans believed that Vulcan, god of fire and metalworking, had a blacksmith shop atop a mountain on this island.
