Climate is the common pattern of weather that happens in an area. It includes the temperature, humidity, and precipitation that occurs in an area over an extended period of time. When someone says, “Climate Change”, they mean that these three factors are changing over time. The sun is the biggest

Have you ever wondered how to identify rocks? In this article, we will talk about six different ways to recognize a rock. 1. What color is your rock or mineral? Different rocks and minerals are composed of different chemicals and elements. Because of them, the colors of the rocks/minerals

The earth's crust is made of tectonic plates, which are giant pieces of land that sometimes collide. A few events that happen on collision are: folding, faulting, a dip slip, and a strike slip. Folding happens when two parts of a tectonic plate push against each other, forming

Igneous rocks, form when melted rocks cools and solidifies. Some form under the Earth's surface, while others form above it. There are two types of igneous rocks: intrusive igneous rocks and extrusive igneous rocks. Intrusive igneous rocks form while underground. Slow cooling that occurs there allows large crystals

Sedimentary rocks are formed by the accumulation of sediment. There are three types: clastic sedimentary rocks, chemical sedimentary rocks, and organic sedimentary rocks. Clastic sedimentary rocks form when the sediment looses all its moisture, it dries up and turns to stone. The weight of all the sediment on top compacts

Metamorphic rocks are called this way because they are formed when other rocks "morph" into a different rock. Due to the movement of the crust, rocks are sometimes pushed underground. Between 100 and 200 kilometers under the earth, rocks start melting from the heat of the core. When
Earth Learning
Sedimentary rocks are formed when pieces of different rocks become joined together to form sediment. A few examples of this type of rock are chalk, sandstone, and limestone. When sediment is picked up by rivers and wind, it is usually deposited at the bottoms of rivers and lakes, where the

When you heat up a chocolate bar what happens? This is almost exactly what happens with rock that is heated up. Heating It takes a lot of heat to melt rock and that type of heat is only found in the depths of the earth. The rock is constantly being

Weathering is the process by which environmental forces break down rocks and soil to form sediment. There are two types of weathering, called mechanical and chemical. Mechanical weathering is when sediment is created through physical means. There are a few types of mechanical weathering. * Thermal expansion and contraction occur when

There are three types of rocks: sedimentary, metamorphic, and igneous. Sedimentary rocks are formed from sand, pebbles, shells, and other fragmented materials. Together, these particles are called sediment. Gradually, the sediment piles up into layers, hardening into rock. Some examples of these rocks are conglomerate and limestone. Metamorphic rocks are

It is believed that there once was a gigantic continent called Pangaea. The first person who had this theory was Alfred Wegener, who thought that 250 million years ago, all the continents were together in one big continent, which he called Pangaea, which was the Greek word for "all

A volcano is a large opening in the earth's crust from which erupt magma and ash. The coolest volcanos for me are: the tallest, the widest, and the most active. Ojos Del Saldo is currently the tallest active volcano on earth. It is exactly 22,615 ft tall.
