Answer:
lightning fatalities more frequent today than as they were in the 1950s .
Explanation:
The frequency of lightning has significantly increased after the 1950s . This is because of global warming or the global rise in the temperature . As the temperature is increasing the chances for the formation of a thunderstorm is also increasing . That's why the more the thunderstorm, the more will be the lightening and the more will be the death fatalities.
According to the date, there is a 50% increase in the lightening in the last 30 years.
Answer: Putting things in order from youngest to oldest.
Explanation:
Relative dating entails the placing of events in a sequence of their occurrence based on relationships between earth materials. In order to date a rock using the techniques of relative dating, some principles are usually followed. Some of the principles of relative dating are:
Principle of superposition
Principle of original horizontality
Principle of lateral continuity
Cross-cutting principle
Principle of fossil and fauna succession.
All of these principles helps establish succinct relationships between rock layers and what they contain. Fossils which are the preserved remains of organisms in rocks are very essential in relative dating of rocks.
Putting things in order from the youngest to the oldest is relative dating. Other options are categorized as absolute dating. In absolute dating, an exact date is affixed to a geologic event.
Answer:
1. disk
2.halo
3. globular cluster
4.spiral arm
5. spiral galaxy
6. bulge
Explanation:
1. In Spiral or Lenticular galaxies, the galactic disk is the flat portion that consists of 2 components; the stellar component and the gaseous component. The stellar component consists of the galaxy stars while the gaseous component consists of cool gas and dust.
2. The galactic halo is the first portion of the galaxy to be formed. Formation of halos is caused by increased gravitational effects and the presence of primordial black holes. When baryonic and dark matter merges, halos are formed.
3. A globular cluster is a large compact spherical star cluster, typically of old stars in the outer regions of a galaxy.
4. Spiral arms are region of a large concentration of stars in a spiral galaxy. This large concentration of stars are usually very bright and easily noticeable.
5. The Milky Way galaxy consists of flat, rotating disk containing stars, gas and dust, and a central concentration of stars known as the bulge. The spiral arm that I explained above extends from the center of spiral galaxies. This extension makes it resemble a spiral and thus give spiral galaxies their name.
6. The bulge is a large concentration of stars.
