Match the subatomic particle with the charge and location.

• No charge, located in the nucleus

• Neutrons

• Positive charge, located in the nucleus

• Electrons
• Negative charge and orbiting the nucleus

• Protons

If electrons are added to an atom, the atom becomes​ (a)   charged.

If electrons are removed, the atoms becomes​ (b)   charged. Atoms with additional or less electrons are called​ (c)   .

• positively
• negatively
• ions
• neutral

Like charges

(a)   . Opposite charges​ (b)  

• repel
• attract
• combine
• neutralize
• cancel

A generator is a machine that converts mechanical energy into electrical energy.

• True

• False

Electric field is...

• An area around a charged object where electric forces are exerted.

• A constant field that does not change with distance.
• A field that describes magnetic forces only.
• A scalar field representing temperature variations.

How tides are formed?

• Tides are formed by the gravitational pull of the moon and the sun on Earth's oceans.
• Tides are a result of wind patterns across the ocean.
• Tides are influenced by the Earth's rotation alone.
• Tides are caused by underwater volcanic activity.

Examples of mechanical weathering are...

• Chemical erosion, sediment deposition, volcanic activity.
• Soil formation, plant growth, nutrient cycling.
• Glacial movement, tectonic shifts, ocean currents.
• Freeze-thaw cycles, abrasion, root expansion.
