Iceland and New Zealand are two places in the world where geothermal energy provides a cost-effective energy resource because these countries have an active volcanic area.
Geothermal- Geothermal energy is a kind of energy that human gets from the heat of the earth. This is a kind of renewable energy because the earth produces a large amount of heat.
The high temperature of the interior makes the rocks melt and the molten rock comes into the crust of the earth in the form of lava.
Iceland and New Zealand are the two places where so many active volcanic areas are available. This makes new Zealand and Iceland the most cost-effective places on earth for the generation of geothermal energy.

Answer:
air flows from land to water
Explanation:
a sea breeze occurs during the day
the water has a high pressure hence the air flows from water to sea
there is low pressure on the land hence it receives air from the sea
land heats faster than the sea during the day
<h2>The new
European imperialism of the late nineteenth and early twentieth centuries resulted in the carving up of most of the continents of Africa.</h2>
Explanation: This Imperialism gained its incentives from economic, military, political, generous, religious reasons and the growth of new technology.
To expand the markets of European mechanical business throughout the world by selling the products that lacked domestic market.
Businessmen and bankers wanted to invest their excess capital, and foreign investments offered the incentive of greater returns regardless of the risks. They experienced both positive and negative effects of imperialism.
The requirement of cheap labor and quick supply of raw materials was the reason to acquire these unexplored regions.
Answer:
Explanation:
Given that:
Area = 475 acres
The length of the channel (L) = 6870 feet
The average water shield slope (S) = 100 feet/mile
Since; 1 mile = 5280 feet
Burst duration D = 15 min
∴
100 feet/mile = 100/5280
The average water shield slope (S) = 5/264
Using hydrograph method:
The time of concentration 
where;
L = 6870
S = 5/264
min
Since 60 min = 1 hour
32.34 min will be (32.34*1)/60
= 0.539 hour
Lag time 
The time to peak i.e
Since D = 15 min is not equal to 
, then we hydrograph apart from duration lag time.
Then;
Now, we need to determine the peak discharge 
by using the formula:
where
484 = peak factor
Recall that A = 475 acres, to miles, we have:
A = 0.7422 mile²
∴
