Answer:
c = 55° and d = 125°
Explanation:
Given that,
We need to find the measure of angle c and angle d.
We know that the sum of angles of a triangle is 180 degrees. So,
a+b+c = 180
85+40+c = 180
125+c=180
c = 180-125
= 55°
Using exterior angle theorem,
d = a+b
d = 85+40
d = 125°
Hence, c = 55° and d = 125°
Question: Which statement best explains why Earth’s outer core is in liquid form?
The iron-nickel alloy melts due to hot temperatures.
The outer core has a tarry consistency.
This region is less dense when compared to the mantle.
This region is under extreme pressure from the weight of other layers.
Answer:
The statement here that bet describes the Earth's outer core is in liquid form " The iron-nickel alloy melts due to hot temperatures."
Explanation:
The outer core of the Earth's is made up of fluid layer which is about 2400 km thick and basically made from iron as well as nickel alloy. This layer lies just above the solid inner core and below it mantle is present. The core of the Earth works like a furnace for the whole composition. It holds the intense heat as well as pressure that helps is maintaining the iron and nickel in the molten state.
High mountain and Desert are the climate zones can be found anywhere on earth no matter the latitude location
Answer: Option C
<u>Explanation:</u>
The tropical, temperate and the polar zones are only found on certain extent on the surface of the earth like tropic of cancer extends from 0 to 23.5 degrees, temperate extends from 23.5 to 66.5 degrees and polar from 66.5 to 90 degrees but mountains and desert are the ones which are found on almost the whole surface of the planet not considering the latitude of the planet.
Extreme or strong tornadoes can reach up to 300 miles per hour.
