The mantle is actually a liquid. The intense heat of the core of the Earth causes the mantle to move in convection currents.
Answer:
Census
Explanation:
A census is the process of data collection and is the systematic acquisition of data about the given population.
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°
They are proportionate. Explanation: See if they are equal. You can divide the numerator and the ..
