What star has a temperature of 20000

Answered By: Jonathan Jenkins Date: created: May 12 2022

Blue stars are extremely hot, red stars are relatively cool.

Temperature here is a relative thing; cool means temperatures near 2,000 to 3,000K, about 15 times hotter than your oven.

Blue stars have temperatures near 20,000K.

The Sun is an intermediate yellow star with a surface temperature of 6,000K..

Question: What Are 4 Causes Of Erosion?

What are 4 things that cause erosion? Liquid water is the major agent of erosion on Earth.Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment.Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.. What are the human activities that cause soil erosion? Soil erosion occurs naturally by wind or harsh climatic conditions but human activities include overgrazing, overcropping and deforestation. Overgrazing occurs when farmers stock too many animals such as sheep, cattle or goats on their land. How can erosion be prevented? Crop Rotation: Rotating in high-residue crops — such as corn, hay, and small grain — can reduce erosion as the layer of residue protects topsoil from being carried away by wind and water. Conservation Tillage: Conventional tillage produces a smooth surface that leaves soil vulnerable to erosion. What is the…
