Match the definition

• Evaporation

• So much water collects in the air that the clouds get heavy, and the water falls as rain, sleet, or snow.

• Accumulation

• The water from the rain, sleet, and snow falls back into rivers, lakes and oceans.

• Condensation

• Water Vapor in the air becomes liquid and comes together to form clouds.

• Precipitation

• The sun heats up the rivers, lakes, and even the ocean, turning water into a hot gas. The vapor rises into the air.

What are the ocean currents?

• Is the movement of streams of ocean water.

• Is the movement of the rivers.

• The ocean waves.

True or false:

There are deep underwater currents that circulate across the world. ​ (a)  

The density of the seawater is not important for the currents. ​ (b)  

• True
• False

The density of the water is determined by temperature and ________.

Cold water is more _____ than warmer water.

As cooler water _____, warmer water _____ to take its place.

What is the name given to the global system

of movement of ocean water via deep underwater currents, driven by thermohaline circulation?

​ (a)   is a natural area with a particular climate and primary type of plants and animals.

• Biome
• Ecosystem
• Nature
• Types

Match the biome with its description

• Grassland

• Home to a variety of trees and other plants. They can be separated into three different categories: temperate forests, taiga (or boreal) and rainforests.

• Aquatic

• These biomes are extremely dry areas. Depending on their location, they can be either hot or cold. Plants and animals have evolved over time to adapt to the
  harsh environment.

• Desert

• This is the coldest biome and therefore has little plant and animal variety.

• Forest

• The majority of this biome is made up of a variety of grasses with very few trees or large plants

• Tundra

• This is the largest biome on Earth and covers nearly 75% of our planet. The biome can be divided into two main categories: freshwater
  and saltwater.
