Water Source Heat Pumps
12/06/24
“How can a heat pump use water as a source?”
Heat pumps take heat from one medium and transfer it to another. Water Source Heat Pumps extract heat from a body of water to heat a desired space. Water source heat pumps typically have a higher heat transfer rate than ground source heat pumps.

Extrusive Rocks
12/05/24
“What happens when lava cools in rocks?”
Lava is a powerful, hot, liquid substance. When it comes to the Earth’s surface and cools, it can solidify into rock. This becomes a type of igneous rock called Extrusive Rocks. Extrusive rocks have large crystalline structure sizes that can be seen by normal human sight and a lack of flow texture. Extrusive rocks have small, even microscopic crystal sizes because of the quick cooling. Examples of extrusive rocks include basalt and obsidian.

Intrusive Rocks

“What happens when magma cools and solidifies inside the Earth’s crust?”
Magma is a powerful, hot, liquid substance. But deep in the Earth’s crust, it can cool and solidify into rock. This becomes a type of igneous rock called Intrusive Rocks. Intrusive rocks have large crystalline structure sizes that can be seen by normal human sight and a lack of flow texture.

Igneous Rocks
12/03/24
“What rocks are formed when molten rock cools and solidifies?”
Rocks are formed through all sorts of manners. Some rocks form when magma or lava cools and solidifies. These Igneous Rocks form one of the three main rock types along sedimentary and metamorphic rocks.
Boulders
12/02/24
“What are rock fragments greater or equal to 25.6 cm?”
Rock fragments come in all shapes and sizes. Rock fragments that are greater or equal to 25.6 cm are classified as Boulders.
Marine Sediment
12/01/24
“What happens with insoluble particles on the seafloor?”
Sediment is the solid, insoluble material that falls to the bottom of a liquid body. Most of the seafloor is made up of sediment labeled Marine Sediment.
Straits

“What connects two water basins together?”
Seas and water basins are large bodies of water. There usually needs to be a connection. This can come in the form of Straits, or thin strips of water.
Dynamic Programming
11/28/24
“How can we solve a complex programming problem by breaking it into sub-problems?”
Some programming problems can be incredibly complex to solve. But by breaking it into repeatable sub-problems, we can create solutions for these to work into a solution for the larger overall problem eventually. This technique is called Dynamic Programming and can be used in all sorts of applications, ranging from finding the smallest distance between two points to deciding the most optimal way to arrange items in a piece of luggage.
Forest Cover
11/26/24
“How can we measure land occupied by forest?”
Forests are a critical part of our ecosystems. Forest Cover, or the amount of land taken up by forests, is estimated to blanket 31% of the Earth’s land area. Sustaining forest cover is critical for keeping our planet alive and healthy.
