Match each step of the hydrologic cycle with its description Water moves down a surface eventually draining into a lake river etc Water passes through a plant and is released through its leaves Water returns to the Earth as snow ice or rain Water soaks into the soil Heat from the sun converts liquid water to water vapor Evaporation Precipitation Infiltration Transpiration Runoff

2 Water is all around us on land in oceans and throughout the atmosphere Water is constantly moving and changing in a process called the water cycle 3 The water cycle begins with the sun Most of Earth s surface water is in oceans and lakes The sun warms this water and turns it into a gas called water vapor which rises into the air This is called evaporation These drops stick together to form clouds Eventually the clouds become too full of water and the water falls back to Earth as rain snow or ice Back on Earth some water soaks into the ground Some piles up as snow and may become part of glaciers or Ice sheets Lots of water ends up in streams Those streams eventually become rivers which flow into lakes and oceans From there the water evaporates into the sky again and the water cycle starts all over How are paragraphs 2 and 3 organized 1 The paragraphs compare the water cycle with evaporation 2 The paragraphs explain how the water cycle affects the clouds 3 The paragraphs describe the order of events in the water cycle O 4 The paragraphs identify reasons why the water cycle is important

Adapting to Survive Cross Curricular Focus Life Science Living things adapt to their environment so they can survive An organism adapts when it develops a behavior that makes it more likely to survive It can also adapt by forming a physical characteristic or body part that helps it survive In a forest biome some trees grow taller than the other plants around them This lets them reach the sunlight Growing taller is an adaptation that helps trees survive Shorter plants have adapted with their behavior They have learned to live in the shade with less sunlight Animals in the forest have a wide variety of adaptations Monkeys have long tails They can use them almost like another hand This helps them swing quickly through the tops of trees They can even do this while holding their babies or gathering food of ball C Answer the Don t forget find or confi 1 What ar 2 What is the passag 3 Is the a behaviora

3 points Atmospheric changes in Earth s history have caused large temperature changes through time How does knowledge of these past connections between atmosphere and climate inform us about modern day climate change Understanding the increased levels of carbon dioxide led to the ice ages humans can avoid causing a new ice age Understanding that increased levels of carbon dioxide led to warmer climates humans can better understand their effect upon global climate and mitigate human caused changes The past atmospheric changes have no effect on modern life because Earth has changed too much
