100

This is the property that determines whether an object will sink or float in water

Relative Density

100

These types of forces act on an object to cause a change in its motion or position

Unequal Forces

100

Earth performs this action on its axis once every 24 hours, resulting in the day/night cycle

Rotation

100

These three events represent rapid changes to the Earth's surface that happen in a very short time

Volcanoes, Earthquakes, Landslides

100

A healthy ecosystem requires organisms to interact with both

Biotic and Abiotic Factors

200

These types of materials, such as metals, allow thermal or electrical energy to flow through them easily

Conductors

200

 In a functioning circuit, electrical energy can be transformed into these four other forms of energy

Mechanical, Light, Sound, Thermal

200

The appearance of the Sun moving across the sky causes these to change position and shape throughout the day

Shadows

200

These are formed over millions of years through the processes of weathering, erosion, and deposition

Sedimentary Rock

200

These diagrams show how energy flows from the Sun to producers and then through various consumers

Food Web
300

This law states that matter is neither created nor destroyed when substances are combined into a solution

Conservation of Matter

300

Light is known to travel in this path until it strikes an object or moves through a different medium

A Straight Line

300

This massive body provides the energy that drives the water cycle and affects weather

The Sun

300

Coal, oil, and natural gas are energy resources formed from the remains of ancient organisms

Fossil Fuels

300

A turtle hatchling returning to the sea is an example of

Instinctual Trait

400

A combination of substances, like iron filings and sand, where each part maintains its original physical properties

Mixture

400

This phenomenon occurs when light bounces off a shiny surface like a mirror

Reflection

400

This term describes the long-term average of weather patterns in a specific region

Climate

400

This triangle-shaped landform is created by the slowing down of water as it meets another larger body of water.

Delta

400

These organisms, such as fungi and bacteria, play a critical role by breaking down dead matter and recycling nutrients

Decomposers

500

This term describes a specific kind of mixture where one substance dissolves uniformly into another

Solution

500

This occurs when light bends as it passes from one medium (like air) into another (like water)

Refraction

500

In the water cycle, this process occurs when liquid water is heated and turns into water vapor

Evaporation

500

Humans use these two methods to conserve natural resources and minimize environmental impact

Reducing, Reusing, or Recycling

500

What can you conclude about Texas since there are oil deposits here?

There was a shallow sea over Texas
