<u>Answer:</u>

Space travellers or astronauts may have to face hazardous health conditions like hypothermia due to the absence of heat.

Meteor showers can also cause a serious threat to the spacecraft and the astronauts in it.

<u>Explanation:</u>

When space travellers or astronauts are on a long space mission, they are vulnerable to a number of health hazards.

Hypothermia (death due to freezing) and meteor showers are the ones that can cause the greatest damage to life and property in the space.

To protect the astronauts from hypothermia, the spacecraft needs to be equipped with proper insulation so that the spacecraft doesn't stand vulnerable to temperature drops.

To protect the astronauts from meteor showers, the spacecraft should be equipped with the most advanced sensors and engines with a powerful thrust capable enough to allow the spacecraft to change its path quickly.

Continental crust Choose one: A. is less dense than oceanic crust. B. makes up about 80% of the Earth's surface. C. is less buoy

kondaur [170]

Answer:

A. Continental crust is less dense than oceanic crust.

Explanation:

Earth's crust can be divided into two categories, oceanic and continental. More of the surface is covered by oceanic crust, but because ocean crust is thinner than continental crust, the volume of the latter is significantly greater.

Oceanic crust is also denser than continental crust as it is made up of basaltic rock, whereas it's continental counterpart contains a type of less dense rock called felsic.

Why is the inner core of the earth in solid state while there is high temperature

zaharov [31]

The pressure on the inner core is greater than on the outer core and the melting point of iron, and because the pressure effect is higher than the temperature effect, the inner core is solidified.

Answer:

at 4 p.m Baghdad located at 45°E

at 8p.m Indonesia is located at x°

we have

common difference in time =8p.m-4p.m=4hours =4×60min

again

we have

4min=1°

4×60min=4×60/4=60°

since time is in p.m on both so they lie in same direction

Therefore, longitude of Indonesia=60°E.

hope this helps you. thanks

Which of the following volcanoes would you expect to erupt explosively : A volcano located near a subduction zone, or a volcano

svp [43]

Answer:

The volcano over a mantle hotspot

Explanation:

I say this because lava comes from the grinding of those mantles, which melt rocks and make lava. If the mantles are super active, the lava will more than likely be explosive. Think of this (heat wise) as tea boiling in a kettle. The stove is the mantle, kettle as volcano and water as lava. When the mantles get hot enough they push that heat and pressure into the water, making it boil and when the steam starts to squeal out of the kettle, the volcano has erupted. Hope this helped!
