Sea: Explanation and Study Guide

Explanation

The sea is a large body of saltwater that covers most of Earth's surface. It is a crucial component of the Earth's hydrosphere and plays a vital role in regulating the planet's climate and weather patterns. The sea is home to a diverse range of marine life and provides essential resources for human activities such as fishing, transportation, and recreation.

Key Concepts

Hydrosphere: The sea is a major part of the Earth's hydrosphere, which includes all the water on the planet.
Marine Life: The sea supports a wide variety of plants and animals, including fish, mammals, and invertebrates.
Climate Regulation: The sea plays a crucial role in regulating the Earth's climate by absorbing and releasing heat, and influencing weather patterns.
Human Interaction: Humans rely on the sea for food, transportation, and recreational activities such as swimming and surfing.

Study Guide

Here are some key topics to focus on when studying the sea:

Formation and composition of the sea
Global ocean currents and their impact on climate
Biodiversity and ecosystems within the sea
Human impacts on the sea, including pollution and overfishing
Importance of the sea for human societies and economies

PHYSICAL SCIENCE (NGSS)

Matter and Its Interactions

Students who demonstrate understanding can:

Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.

Energy

Students who demonstrate understanding can:

Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.

Plan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system (second law of thermodynamics).
