What Causes a Volcano to Erupt? | Owlcation

Volcano eruptions happen when magma erupts from beneath the Earth’s crust. When a volcano erupts, the magma becomes lava and shoots into the air, eventually running down the side of the volcano.

To understand how and why volcanoes erupt, we must first understand the different layers of our planet.

The three layers of Earth are the core, mantle, and crust.

The Layers of Planet Earth

Earth is made of three layers: the core, the mantle, and the crust. The core is comprised of inner and outer sections. The mantle has lower and upper mantle areas, too. The crust, though, consists of one main layer.

The Earth’s core is solid iron, and pressure in this

The types of clouds: everything you need to know by Tibi Puiu

Clouds come in all sorts of shapes and sizes. Some look cute and fluffy, others appear menacing and apocalyptic.

Not all clouds are created equal. Some are puffy and sweet, others are gray and uniform while others still are so erratic and capricious that the human mind starts to see things; bunnies, cows or a nation’s borders.

The different types of clouds are named based on their shape and how high up they hover in the troposphere. For instance, the diagram below provides a quick overview of the most common types of clouds based on altitude.

The three main types of clouds

A cloud is a visible accumulation of minute droplets of wate, ice crystals, or both, suspended in the air. Though they vary in shape and size, all clouds are basically formed in the same way through the vertical of air above the condensation level. Clouds may also form in contact with the ground surface, too. Such a cloud would be known as fog

How to Identify the 10 Different Types of Clouds Posted by Christine Sarikas

Do you need to know the different types of clouds for school, or are you just interested in what’s up there in the sky? At first glance, all clouds can look pretty much the same, but with a bit of knowledge and practice you can soon learn how to tell exactly which kind of cloud you’re looking at.

In this guide, we show you all the steps to becoming a cloud-identifying expert. We’ll go over the ten main types of clouds and give you the info you need to identify each cloud type, including cloud names, their shape, height in the sky, color, and the weather you can expect them to bring.

We’ll end with some additional tips for identifying clouds, including easy tricks to differentiate similar-looking cloud types.

The 10 Main Types of Clouds

How many types of clouds are there? Generally speaking, there are ten main types of clouds you’ll see in the sky, and we discuss each of them below. For each of these different types of clouds, we’ve included a picture of the cloud, a short description, and the following additional information:

  • Height: Where in the sky the cloud typically occurs (low-level, mid-level, or high-level)
  • Color: The color of the cloud
  • Shape: The form the cloud typically takes
  • Weather: The weather the cloud is usually associated with or predicts

 

Altocumulus

  • Height: Mid
  • Color: White
  • Shape: Heap-like and often grouped together
  • Weather: Varies

Altocumulus clouds are fairly common clouds that look like round white or gray patches in the sky. They are sometimes grouped in parallel lines and have been described as looking similar to tufts of wool or fish scales.

 

Altostratus

  • Height: Mid
  • Color: White or light gray
  • Shape: Thick and flat
  • Weather: Usually indicate warmer weather is approaching; can cause light precipitation

These clouds form a white or gray layer that blankets the sky at mid-level. There are usually no patches of blue sky when these clouds appear, but the sun is often visible as a dimly lit disk behind the clouds (although no shadows appear on the ground).

 

Cirrocumulus

  • Height: High
  • Color: White or gray
  • Shape: Rows of small patchy clouds
  • Weather: Typically sunny and cold

Cirrocumulus clouds are much smaller than most other types of clouds, and they are sometimes called cloudlets. They are found at high altitudes and are made of ice crystals. They often are arranged in parallel rows. They are one of the rarer types of clouds and usually don’t last long.

 

Cirrostratus

  • Shape: Wispy, but thicker than cirrus clouds
  • Weather: Varies

These are transparent, wispy clouds that
