1) The document is an activity worksheet about relief and water on Earth. It contains questions about diagrams of Earth's interior, tectonic plates, volcanoes and earthquakes. 2) It also asks students to identify features of rivers and coastlines like deltas, tributaries, and meanders on a diagram. 3) Students are tasked with describing a picture using coastal and river terminology. 4) The document provides a reading on issues around access to clean water and asks related questions to assess comprehension. Key points are the health impacts of contaminated water, efforts to expand access, and proposed solutions like more efficient agriculture.

5- Read the following text of the National Geographic review and contest the questions:
Clean water is essential for life, but most people in the developed world don't think much about the water they
use for drinking, food preparation, and sanitation. In developing nations, however, the search for safe drinking
water can be a daily crisis. Millions of people die each year, most of them children, from largely preventable
diseases caused by a lack of access to clean water and proper sanitation. The intersection of water scarcity,
food security, and a changing climate on top of it all raises a suite of water concerns that urgently need to be
addressed.
Much progress is possible. In fact, due to the dedicated efforts of governments and NGOs since the 1992
Earth Summit, safe drinking water has been made available to some 1.7 billion people around the world, with
projects ranging from modern piped plumbing to rainwater collection and storage. But an estimated 880 million
people still don't have regular access to clean water.
About 5,000 children die each day due to preventable diarrheal diseases such as cholera and dysentery, which
spread when people use contaminated water for drinking or cooking. A lack of water for personal hygiene leads
to the spread of totally preventable ailments like trachoma, which has blinded some six million people.
Water misery also traps many low-income families in a cycle of poverty and poor education—and the poorest
suffer most from lack of access to water. People who spend much of their time in ill health, caring for sick
children, or laboriously collecting water at distances averaging 3.75 miles (6 kilometers) a day are denied
educational and economic opportunities to better their lives.
"Seventy percent of all the water we use globally is for agriculture, so that's where we first have to become a
lot more efficient through methods like drip irrigation and growing crops that are more suitable to the local
climate," Postel said. "We still have too few incentives for farmers to use water more efficiently. Farmers are
good businesspeople; they respond to incentives that affect their bottom line."
The United National General Assembly has recognized "the right to safe and clean drinking water and sanitation
as a human right that is essential for the full enjoyment of life and all human rights." Making that right become
a universal reality, and providing each person on the planet with affordable access to the 20 to 50 liters of
daily water required to sustain life, is a clear goal for the decades ahead.
a) What is the main idea of the text in your opinion?
b) Are there any other problems that make the water scarcity a worse problem?
c) Explain some diseases or any other problems that cause the lack of water in the developing
countries.
d) Consider some of the possible solutions to these problems and explain how you can make
something to help in your daily life.
