The one that is blue is a hotter star
When studying the temperature of a star, the scientists first look for color. If the color is more reddish, it’s cooler; if it’s yellow/orange, it is a warmer star; and if it’s a blue star, it’s a hot star
Answer:
Option D is correct.
Explanation:
Euphorbia esula is commonly known as leafy spurge, it's a creeping perennial native from central Europe, and most of north Asia.
The leafy spurge has deep roots, that store vital nutrients that allow the plant to recover from most control efforts.
Each plant can produce around 140 seeds per flowering shoot, these seeds are then expelled up to 15 ft. They can subsist up to 8 years in the soil.
This allows the plant to grow exponentially as it infests new regions.
“The vast majority of Egyptians live in Egypt where they constitute the primary ethnic group at 97-98% (about 76.4 million) of the total population. Approximately 90% of the population of Egypt is Muslim and 10% is Christian (9% Coptic, 1% other Christian).”
Whether an eruption will produce lava flows or pyroclastic debris depends on the viscosity of magma and the gas content
<h3>What is a Volcano?</h3>
This refers to the eruption of hot lava from the surface of the earth as a result of a tectonic shift.
Hence, we can see that the two main factors that determine the content that comes out when an eruption occurs are both the viscosity of the magma and also the gas content.
