My next topic I’m sure will interest all of you- I want to talk to you now about Black Holes. Simply speaking, a black hole is what’s left after a large star dies. Click here to read full transcript

You’re already aware that a star is an energy producer, a nuclear fusion reactor- its core is a gigantic nuclear fusion bomb that’s trying to explode- but its mass of surrounding gases is so large that its gravity contains the explosion, and the balance that exists between the gravity and the fusion is what determines the star’s size.

However, as a star gets older, as it ages, its fuels gets used up and its nuclear reactor slows down. And then, its gravity gets the upper hand. The star implodes. Gravity pulls inward and compresses the stellar material into the star’s center. As it’s compressed, the core heats up tremendously- and then, at some point, a supernova, a great explosion, occurs, and the stellar material and a lot of radiation are blasted out into space. Only the extremely dense, extremely massive core is left. Its gravitational field is so strong that nothing can escape it, not even light. So it disappears from view: it’s black. It’s now a black hole.

TRANSCRIPT (Only for reference, it will not be given in actual PTE Academic Test)

Good morning, class. It’s a beautiful spring day outside, isn’t it? We’ll soon be seeing the first robin of spring- and so, it’s a perfect day to begin talking about migration.Click here to read full transcript

Migration is the main strategy that animals have for avoiding adverse environments and taking advantage of rich environments. Of course, there are other strategies, too- hibernation, for example- but far and away the most common way for animals to escape poor conditions and get to better ones is by migration- a mass journey from one place to the other.

Now there are all kinds of migrations, but the most familiar one is the sort that our robins will be experiencing- a seasonal, latitudinal migration. In the fall, the birds fly south, and in the spring they fly north again. In the southern hemisphere, of course, this works in the opposite direction. In both hemispheres, migrants move toward the equator when the earth chills and toward the poles when it warms. This is the way that species have been able to colonize, to use those subpolar resources that are seasonally difficult to access, that are unavailable to many living things for half the year.

Birds are certainly the most conspicuous latitudinal migrants, and they’re also the most awesome. Most famously, the Arctic Tern, which is a small seabird, migrates from one pole to the other, all the way from the Arctic subpolar region to the Antarctic subpolar region- and back again- annually. These birds travel roughly 70,000 kilometers a year!

  • Lecture was discussed in spring day, about Animal migration throughout the year
    he discussed that this occurred due to environmental changes and
    and mass journey.
    He also explained two types of migration, which is seasonal
    and latitude migration are the most famous.
    Furthermore, he also tells us about see birds, which travel 70 thousand kilometers
    annually for the purpose of food and water in worm season.

  • The speaker speaks about Black hole and its formation in the universe. According the speaker black holes are formed when star dies due to exhaust of hydrogen and helium gases, due to this gravitational forces increases and star explodes by creating black hole . Because of huge gravitational force the near by stars which is having less gravitation will be pulled towards this black hole.

  • The speaker was speaking about animal migration. Migration is the strategy used by animals to escape from adverse environment and taking advantages of rich environment.
    Environmental changes can be a due to many factors but the factors such as seasonal change and latitudinal change are the major ones. Birds usually travel from south to north in spring and vise versa in fall. for an example arctic tern travels almost 70,000 Km per year as per its migration strategy.

  • In this topic the lecturer talks about animal migration, the causes why the animal migrate from one place to another and the reasons that animals experiencing seasonal changes. As he mention that animals also has strategies on how they live like escaping in poor environment, that they tend to flew on the south hemisphere during fall , and flew back to north during spring.because like human they are also sensitive to warm and cold season too. This is why birds migrates from one pole to the other and famously travel annually by 70,000 kilometers per year.

  • The lecture is about migration.
    He defined migration as strategy that animal used for avoiding adverse environment and taking advantages of rich environment. And other reason mentioned as hibernation means to escape form poor condition to better condition.
    There are many kinds of migration but most familiar one is seasonal latitude migration. According to seasons animals are moving to poles.
    Also birds are mentioned as most conspicuous latitude migrants given as a example of Arctic Tern which travels around 70000 km per year roughly.
    In conclusion we can say that migration is the phenomenon seen by animals.

  • The lecture is about animal migration which animals escape from one place to another. For example in Sourthern Hemisphere birds would move from cold areas to warmer weather. Also seabirds are beautiful and awesome they usually move from sub polar region.

    • The lecture is about migration in which animals are going from one place to another. They are going because, they are going to rich environment and escape adverse environment. Furthermore,
      there are mainly two types of migration. One is seasonal and second is latitudinal. In the fall, birds are going in south direction and in spring, they are going to north direction. The bird namily arctic tern is famous seabird migrate from one pole to another. Even this birds travels a distance of 70,000 km per year for migration.
